Wall of [fire, force] questions

[Ironballs]

Fire: according to the spell, you can either create it as a straight line wall or a circle only? is it anywhere specify that the wall can't be curved slightly or zig-zagged or something ?

Force: according to the description, this wall can't be made as a circle at all - shouldn't the same shape rules apply to all walls ?

1. The problem is that there is nothing that specifies that you CAN. Spell descriptions are exclusive. They exclude any capabilities not present in the spell text. By your argument one could say I could cook breakfast with a fireball, because there's nothing in the spell description that says you can't. Also there is no provision for "slight curvature" when plotting spell effects on the grid.

2. Rules are by spell. There are very few general rules regarding walls because they differ in so many ways.

The same rules don’t apply to all Wall spells, some Wall spells are Shapeable others are not. You have to look in the Effect descriptor. For example:

Wall of stone is shapeable

Effect: stone wall whose area is up to one 5-ft. square/level (S)

Wall of Fire is not

Effect: opaque sheet of flame up to 20 ft. long/level or a ring of fire with a radius of up to 5 ft./two levels; either form 20 ft. high

From PRD: Magic: Area:

Quote:

S) Shapeable: If an area or effect entry ends with “(S),” you can shape the spell. A shaped effect or area can have no dimension smaller than 10 feet. Many effects or areas are given as cubes to make it easy to model irregular shapes. Three-dimensional volumes are most often needed to define aerial or underwater effects and areas
