[GM Glyn]

Question about the area affected by wall of fire and Loathsome Veil spells.
(There may be more spells like these.)

Case 1: Does the spell only affect the rectangle area perpendicular to the wall segment.

or

Case 2: The spell affects the rectangle area perpendicular to the wall segment and extends beyond both the wall's end points to the range of the effect. Effectively adding a quarter pie shaped area to both side of the center rectangle.

Loathsome Veil {link}

[Fuzzy-Wuzzy]

They are both written to affect "all creatures within X feet," with no restriction to perpendicular displacement, so case 2.
