Spell

A sphere of radius_ft, centered on the target point (fireball).

A cone of length_ft, thrown from the caster toward the target (burning hands).

A line of length_ft, thrown from the caster toward the target (lightning bolt).

A burst of radius_ft centered on the caster (thunderwave's "Self" cube, radius-approximated on the grid).

A spell attack roll (d20 + PB + casting mod vs AC), once per ray — each hit delivers the effect list (scorching ray rolls three).

Unerring bolts (magic missile): every dart lands, no roll.

A saving throw against the caster's DC for everyone caught — the named target, or every combatant an [Area] takes in. A SUCCESS spares per [OnSave]; non-damage effects land only on a failure.

The named ally plus the worst-hurt others in range, up to targets (mass healing word's six) — the derived-policy pick.

The named target alone, no roll — the touch utilities.

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

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

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

Kindle the target as a carried flame for the hour (the LIT_UNTIL machinery, 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.

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, occupied square, or board edge. 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 summon: a CONCENTRATION conjuring that mints creature_id from the bestiary onto the caster's side mid-fight — the conjured wolf of Conjure Animals. Established on the delivered target (the caster — a Target self-cast); BENEFICIAL (it adds an ally). The beast fights via the existing NPC AI and VANISHES when the caster's concentration breaks. LEDGERED: the variable creature COUNT (ship one; the CR-by-slot table is a fan-out) and the PLAYER's choice of what to conjure. Transient: commanded by its caster, it 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 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"). LEDGERED: the SRD 1-hour duration (temp HP has no clock in the bubble) and false life's flat +5-per-slot upcast (a flat-per-slot axis unmodelled — DicePerSlot is dice).

A resistance grant: the delivered target gains resistance to kind damage — protection from energy's ward, halving that one kind — for the CONCENTRATION duration. BENEFICIAL (a Target/Allies self-or-ally cast); an ongoing effect sourced by the caster, lifting when its concentration breaks (the source-keyed spell_resist pool). LEDGERED: the player's choice among the five energy kinds (ship one — fire) and the SRD 1-hour cap.

SRD 5.1 — the System Reference Document, the shipped baseline.

Original content authored for this game (not from the SRD).

A player's own transcription or third-party content in a mod tree — provenance stays honest without borrowing the base tree's markers. Never used by shipped files.

Touch — the caster must reach the target (SRD "Touch").

A ranged spell out to this many feet.

Self — the spell affects only the caster (SRD "Self").

No higher-level text.

+String dice per slot level above the spell's own: onto the FIRST cast-time dice step (its damage or its heal), and onto EACH ongoing damaging effect (zone/aura/wall-burn/beam), baked into the effect's stored dice at cast.

+1 dart/ray per slot level above the spell's own.

+1 TARGET per slot level above the spell's own: bless's extra ally, hold person's extra foe. On an Allies delivery it bumps the target count; on a single-target Save (area None) it adds that many nearest enemies within range. The sibling of ExtraPerSlot — that fans out projectiles at one target, this fans out DISTINCT creatures.

+i64 FLAT per slot level above the spell's own: false life's +5 temporary hit points a slot. Added to the first cast-time dice step's flat total (its rolled amount), NOT its dice — the flat-number axis DicePerSlot (dice) cannot express.

A conjuring's creature COUNT doubles per TWO slots above the spell's own: conjure animals' "twice as many at 5th, three times at 7th, four times at 9th". Mints 1 + (slot − level) / 2 copies of the summon.
