Nonlethal Field (3.5e Spell)

''The warlock fires a vitriolic blast at you just as you finish muttering the incantations. You faint from the attack, but right before you close your eyes, you watch as your barbarian buddy rushes to strike the warlock.''

You create a sphere that has a minimum radius of 10 feet and a maximum radius of 5 feet per caster level, though you may decide its radius within that limit. In that sphere, all lethal damage becomes converted to nonlethal damage.

A creature may make a fortitude save upon attacking a creature inside the sphere. If the fortitude save is successful, any attacks done by this creature deal damage normally. Each creature may only attempt this save once. For the purposes of this spell, any environmental damage caused by the actions of another creature is considered an attack by the creature that caused it. Environmental damage caused by the actions of more than one creature is not considered an attack.

Creatures immune to nonlethal damage are not subject to this spell, and suffer lethal damage if hit by an attack that would normally deal lethal damage.
