Effect

Authorize a cast matching an authored spell predicate and independently state which ordinary casting costs or form restrictions are exempt.

Offer parameterized cast changes. Option ids carry provenance only; filters, costs, compatibility, and transformation values drive play.

Offer mutually exclusive, explicitly delivered effect compositions.

Admit spells from authored class lists to preparation without changing the bearer's ordinary prepared-spell capacity.

Atomically exchange one authored resource ledger for another through a finite conversion table. Resource identity, rates, caps, and use economy are all parameters; a feature id never selects the rule.

Raise a named resource ledger to at least an authored amount, without exceeding that ledger's ordinary capacity.

Permit an authored Hide context while its action and equipment gates hold. This describes the context, not the granting feature's identity.

Permit one movement mode to traverse the listed otherwise-forbidden surfaces while an optional unarmored gate holds.

Spend the creature's Reaction when it falls to reduce the fall's damage by an authored amount per granting-class level.

End a source-owned condition when one of the authored lifecycle events occurs. Source ownership is retained by the ordinary persistent effect.

Grant resistance for a bounded duration after atomically charging an authored resource pool. Exactly one included or excluded set is used.

Deal one die per derived ability modifier, subject to an authored positive minimum, using the ordinary damage ladder.

Give attacks selected by authored source filters a damage property.

Amend an eligible damage roll at authored outcomes, with optional once-per-turn accounting.

Atomically exchange parent damage dice or attack Advantage for one or more distinct, level-gated effect compositions.

Derive an increase for the listed ability scores, bounded by cap. This is read from the reached grant and is never repeatedly stamped.

Derive apparent age as elapsed years divided by this positive rate. Elapsed world time itself is unchanged.

Override the bearer's derived magic-item attunement capacity.

Arm one typed one-shot d20 edge on the bearer.

Offer a willing, conscious ally and exchange the two Initiative values.

Roll only the weapon's base damage dice twice and keep the greater sum.

Restore one already-spent turn resource to the acting creature.

Restore hit points from authored dice plus a value derived from the invoking grant and its bearer.

Grant temporary hit points from authored dice plus a value derived from the invoking grant and its bearer.

Apply an authored condition to the bearer for a number of rounds. Lifecycle clauses belong to the application, while the condition's combat reads remain composed in data/conditions.

On the target's next turn, it can only move, take an action, or take a Bonus Action. Its first choice closes the other two for that turn.

Apply a timed condition whose melee attacks receive a level-scaled flat damage bonus and whose bearer resists authored damage kinds.

Apply a timed enhancement to spell attack rolls and spell save DCs.

Grant an authored movement mode at walking speed for a duration. A dismissible grant may be ended by invoking the same action again.

Charge a fixed amount from an authored fallback resource when the action's primary use store is unavailable.

Establish a mobile damaging aura around the bearer for the authored duration. Damage and radius are ordinary parameters, not content ids.

Divide a level-derived healing budget among nearby allies without raising any recipient beyond the authored fraction of maximum HP.

Install or transfer a source-owned mark onto one target in range.

Restore an authored resource pool to its capacity.

Offer an authored number of bonus strikes against one legal target.

Make selected ordinary actions available through the bonus-action economy for the current turn.

Arm the bearer's next eligible hit with typed damage and/or a saving throw that applies an authored condition.

Grant Advantage on the next eligible attack and optionally consume the bearer's remaining movement for this turn.

Spend points from an authored pool to heal a touched ally or remove one of its conditions at the authored cleanse price.

Grant a die selected from an authored level table to one ally in range.

Add one ability modifier to weapon attack rolls for the authored duration.

Offer a save against creatures of an authored type in an area or a level-scaled heal to one target. The choice is made by the action. Each creature that fails the save gains every one of conditions for rounds, against the action's save DC.

Add one ability modifier to allied saving throws made within an aura.

Prevent allies within an aura from gaining one authored condition.

Add authored dice to the roll currently crossing a trigger boundary.

Replace the d20 currently crossing a trigger boundary with an authored face value.

Reroll the failed save currently crossing a trigger boundary and add a value derived from the invoking grant and bearer.

Offer a willing target in range a reroll of a failed save against one of the authored conditions.

After an incoming attack's damage is reduced to zero, permit an ordinary return attack against an eligible target in range.

Suppress Advantage on incoming attacks while the authored awareness gate holds.

Insert another initiative turn in the first round at the authored penalty from the bearer's initiative.

Grant half cover to the bearer and nearby allies until the bearer's next turn begins.

Move the bearer by a fraction of its current speed as part of the boundary transition.

Use Dexterity for jump distance and/or grant a Climb Speed equal to walking speed while the row is active.

Add one ability modifier to a damage roll for a spell of the authored school.

Maximize damage for a spell in the authored school through the stated level; repeated use may apply the ordinary escalating backlash.

Spend authored pool points for each condition removed by a healing boundary.

Make foes in range save or gain an authored condition for a number of rounds.

Add a flat amount plus an amount per spell level to healing crossing the current boundary.

Select the persistent spell behavior.

Select the maximum hit points change behavior.

Reduce the target's maximum HP by the damage the immediately preceding damage step actually dealt, after saves and damage modifiers. The life state kernel floors effective maximum HP at 1.

After a weapon-delivered spell hits its primary target, deal typed damage to one explicitly chosen different creature within this many feet of the primary. The casting ability modifier is optional and the dice follow the owning spell's ordinary cantrip ladder.

Arm the delivered target until the source's next turn starts. The first voluntary move of at least minimum_ft consumes the handle and deals the scaled typed damage; forced movement never enters this door.

Typed damage whose die count follows the cantrip tier multiplier plus an authored signed offset. An offset of -1 expresses riders that begin at level 5 without content-specific branching.

Select the death prevention behavior.

Require one explicit closed authored option before applying this effect.

Compel one typed action; content identity never participates in dispatch.

Require the caster to choose one of several typed commands, then arm that exact forced action on the delivered target's next turn.

Arm a separately typed delayed predicate and consequence.

Replace a target's authored combat form while preserving soul identity.

Change only the target's occupied size category; all other statistics remain.

Temporarily add an authored number of feet to one closed movement mode.

Add one separately typed damage roll to every Unarmed Strike hit for the effect's duration. The rider is its own damage instance (so its resistance and critical-hit dice are resolved independently).

Add one separately typed damage roll whenever the bearer hits with an attack, provided the hit target is no farther away than the authored range. This applies uniformly to weapon, Unarmed Strike, natural, and spell attacks; the rider is a distinct damage instance and its dice double on a critical hit.

While this source-owned effect lasts, the source is offered a no-cost accept/decline choice whenever a creature it can see starts its turn in the authored radius. Choices are queued independently in source order.

Raise the target's Strength score to at least this value for the effect's duration. The stored score is never lowered or mutated.

Grant immunity to one authored condition for this effect's duration. The grant is source-owned, so concentration loss removes only the granting source's immunity.

Temporarily grant one or both breathing media. This changes only the suffocation predicate; it grants no Swim Speed or movement permission.

At the start of each target turn, grant temporary HP equal to the casting ability modifier (minimum zero). Multiple grants obey the ordinary non-stacking temporary-HP rule.

Deal typed damage at the start of each affected creature's turn for this effect's duration. An authored action-removal flag exposes the shared self-or-adjacent cleanse action rather than a spell-specific verb.

Temporarily grant Truesight to at least this range. Existing longer special senses remain authoritative; expiration reveals them again.

Install or resolve a typed pre-resolution defense/cancellation payload.

Modify the next pending fall impact on the target. This is an event primitive rather than a spell-id branch: reaction content supplies the exact reduction and optional controlled-descent rate.

dice (+ plus) damage of kind — halved by a resistance, spared per the delivery's save. A crit doubles the dice (attack deliveries).

Use alternate_dice when the delivered target is below maximum HP.

Damage whose kind is chosen at cast time from this closed authored set. The live and forked policies choose the first kind with the greatest post-mitigation result; content names never enter combat dispatch.

Restore dice (+ the casting mod if add_mod) hit points.

Restore an exact authored number of hit points (no die or modifier).

Restore HP to the effect's source from the immediately preceding damage step's actual post-mitigation applied amount.

Deal irreducible typed damage to the effect's source, then restore the delivered target by an authored multiple of that applied damage.

Remove one currently borne condition from a closed authored set. When several qualify, authored order is the deterministic choice order.

Remove up to this many levels from the target's world-authoritative Exhaustion track. A value of six expresses complete 2024 recovery without coupling the primitive to one item.

For the enclosing duration, every Hit Die the target spends restores the die's maximum result rather than its ordinary roll/average.

Advantage on a closed set of skills only when the check explicitly influences a creature within the authored range.

End a dying ally's death saves (spare the dying).

Kindle the target with an independently timed illumination handle, cast instead of struck, throwing bright_ft of bright light and dim_ft MORE of dim — the SRD's own phrasing ("bright light in a 20-foot radius and dim light for an additional 20 feet"). Light is the torch's 20/20; daylight throws 60/60.

The glimmer (guiding bolt): the next attack roll against the target has advantage.

Bless/bane: die rides the bearer's own attack rolls and saving throws for the duration — added, or subtracted when penalty. A CONCENTRATION effect (the validator pins it), so it lifts when the caster's focus breaks.

Inflict a condition on the target: the id resolves against data/conditions/ at load — a condition is a DATA bundle of engine [ConditionComponent] reads, so hold person's paralysis and a mod's own affliction are the same one-file shape. Behind a Save delivery the bearer repeats that save at each of its turns to shake it (SRD save-ends); a CONCENTRATION effect.

The target's next weapon attack is made with Disadvantage; if unused, this expires at the end of that target's next turn.

Subtract die from the target's next saving throw before the end of the source's next turn. The rider is consumed by the first save attempt, whether that save succeeds or fails.

Forced movement: shove the target distance_ft directly AWAY from the effect's origin (the caster, for the self-centered burst/cone/ line spells that carry it), stopping at the first wall, impassable creature's space, or board edge. It can end in an occupied space it may pass through. A harmful, instantaneous rider behind a Save — forgone on a success. Thunderwave's ten-foot push is the first. LEDGERED: pushing away from a SPHERE's center rather than the caster (no shipped sphere-push spell needs it) and prone-on-collision.

A pull: forced movement TOWARD the caster — thorn whip's vine yank, the mirror of Push. Drags the struck target distance_ft toward the caster (halting adjacent, never onto it). HARMFUL (it rides a to-hit or a save, like Push). LEDGERED: a pull toward a POINT other than the caster.

A sustained beam: a CONCENTRATION drain that deals dice kind to the delivered target AUTOMATICALLY at the start of each of the caster's turns — vampiric touch's per-turn drain (the one-time hit is a separate Damage step; this is the sustain). HARMFUL (rides a to-hit or a save), an ongoing effect (concentration). LEDGERED: the SRD range-break (the beam ends if the target leaves range/cover — ours holds while concentration does), the life-drain self-HEAL (no heal-from-damage primitive yet), and the upcast.

Teleport: the delivered target vanishes and reappears up to max_ft away — misty step's blink. A BENEFICIAL self-move behind a Target delivery. The destination is AI-chosen (the unoccupied on-board square FARTHEST from the nearest enemy — the escape the world uses), following the world-first precedent; a PLAYER-picked destination, the "space you can see" line of sight, and bringing a willing creature (dimension door) are LEDGERED.

An aura: a CONCENTRATION area centered on the caster that bites foes who START their turn within radius_ft — an ability save for half of dice kind damage (spirit guardians). Established on the delivered target (the caster — a Target self-cast); BENEFICIAL for the delivery's side-legality (you cast it on yourself), the harm emergent per-turn. It moves WITH the caster and lifts when its concentration breaks. LEDGERED: the SRD "enters the area for the first time on a turn" movement trigger (start-turn-in only today), the speed-halving, and the upcast (+dice/slot).

A mobile heavily-obscured area centered on the delivered creature.

A transient summon that mints creature_id from the bestiary onto its source's side mid-fight. It may be concentration-bound or independently timed, fights through the ordinary combatant machinery, takes no plunder, and is swept from the world when the fight ends.

A zone: a CONCENTRATION area anchored to a FIXED point on the board (the aura's board-bound sibling — an aura moves WITH its caster, a zone stands where it was cast) that bites whoever starts their turn within radius_ft — an ability save for half of dice kind damage (moonbeam). Established via a Target self-cast; BENEFICIAL for the delivery's side-legality (the harm is emergent per-turn, like the aura), the placement AI-chosen (the foe cluster within range, never an ally — the world-first precedent). LEDGERED: the SRD "enters the area" movement trigger (start-turn-in only today), a MOVABLE zone (moonbeam's beam-step), the cylinder/cube shapes (a Chebyshev radius today), the PLAYER-picked anchor, and the upcast. The movement-blocking WALL (Wall of Force/Stone — blocked squares + line-of-sight) is a distinct primitive, ledgered as the sibling.

A board area whose consequence fires at turn start, on first entry, and/or at turn end. Unlike the older damage-only Zone, this carries the complete authored trigger, use ledger, mobility, exclusions, and removable riders needed by creature-selective healing and hazardous fields.

A sustained rectangular field anchored to its source's current square and an authored orientation. The caller establishes it once; creatures in its footprint are consequences of the field, not separate copies.

A wall: a CONCENTRATION barrier of length_ft that stands a line of BLOCKED squares on the board — Wall of Stone / Wall of Force. It deals no direct damage; it BLOCKS. Every mover, the king-step pathing, the cover / line-of-sight trace, teleport, and forced movement already read board.open, so the wall gates all of them for free (the board footprint + cover seam). Established via a Target self-cast; BENEFICIAL for the delivery's side-legality (it harms no creature directly), the placement AI-chosen (a line cutting the caster off from the foe cluster, never through a creature — the world-first precedent). LEDGERED: the PLAYER-drawn shape/anchor, the panel/ring/sphere forms (a straight line today), a DAMAGING wall (Wall of Fire — a Wall+Zone compose), and the "creatures in the wall's space are shoved clear" rule (gaps at occupants).

A damaging wall: Wall of Fire — a CONCENTRATION barrier of length_ft that BLOCKS (like Wall) AND sears any of the caster's enemies who start their turn on or adjacent to it (an ability save for half of dice kind). Established via a Target self-cast; BENEFICIAL for side-legality (emergent per-turn, like the Zone). LEDGERED: the SRD wall of fire is PASSABLE (ours blocks — a fiery barrier, the fun-first read), its ONE damaging side (ours sears both), the opaque line-of-sight, the player-drawn shape/anchor, and the upcast.

A condition zone: the Zone's SNARING sibling — a CONCENTRATION area fixed to a board point that AFFLICTS rather than damages. A creature starting its turn within radius_ft makes an ability save; on a FAILURE it gains condition (a conditions/ id) for that turn — web's restrained, sleet storm's prone, stinking cloud's incapacitated. Established via a Target self-cast; BENEFICIAL for side-legality (emergent per-turn, like the Zone), the placement AI-chosen. The condition RE-EVALUATES each turn the creature lingers (a made save frees it). LEDGERED: the escape/break-free check, the difficult-terrain rider, the enters-the-area trigger (start-turn-in only), and the upcast.

A temporary hit-point grant: the target gains dice + plus temporary hit points — false life's ward. BENEFICIAL, instantaneous (NOT concentration): temp HP sits on the combatant and is spent before real HP (the dark-one's-blessing pool), taking the HIGHER of any existing pool and the fresh grant (SRD "decide whether to keep"). The authored expiry applies only when expires_with_effect is true.

A resistance grant: the delivered target gains resistance to kind damage — protection from energy's ward, halving that one kind — for the authored duration. A concentration grant is source-owned and lifts when focus breaks; non-concentration item magic expires on its own clock. LEDGERED: the player's choice among the five energy kinds (ship one — fire) and the SRD 1-hour cap outside a combat bubble.

Source-owned advantage on the listed saving throw abilities for the spell's duration.
