An area of effect, resolved on the encounter board's 5 ft grid: a sphere centers on the TARGET, a cone/line throws from the CASTER toward it, a burst centers on the caster (thunderwave's "Self (15-foot cube)", radius-approximated on the Chebyshev grid).
Sphere
A sphere of radius_ft, centered on the target point (fireball).
| Field | Type | Required | Description |
|---|---|---|---|
| radius_ft | uint32 | required |
Cone
A cone of length_ft, thrown from the caster toward the target (burning hands).
| Field | Type | Required | Description |
|---|---|---|---|
| length_ft | uint32 | required |
Line
A line of length_ft, thrown from the caster toward the target (lightning bolt).
| Field | Type | Required | Description |
|---|---|---|---|
| length_ft | uint32 | required |
Rectangle
A directional rectangle with independently authored long and wide dimensions. Placement supplies a near-left corner and a second point choosing its long axis; neither dimension is approximated as a line or sphere.
| Field | Type | Required | Description |
|---|---|---|---|
| length_ft | uint32 | required | |
| width_ft | uint32 | required |
Burst
A burst of radius_ft centered on the caster (thunderwave's "Self" cube, radius-approximated on the grid).
| Field | Type | Required | Description |
|---|---|---|---|
| radius_ft | uint32 | required |
Emanation
A radius centered on and including the origin creature. Unlike a burst, an emanation includes its origin and needs no aim point.
| Field | Type | Required | Description |
|---|---|---|---|
| radius_ft | uint32 | required |
