Invocation Grade: Greater
Equivalent Spell Level: 5th
You can conjure a wall of fire as the spell with this invocation. Half the wall’s fire damage results from supernatural power and is therefore not subject to being reduced by resistance to fire. If a creature is reduced to 0 hit points or lower by a wall of perilous flame, its remains are completely consumed 1 round later (as if by a destruction spell).
