Invocation Type: Greater
Spell Level Equivalent: 5
You conjure a curtain of fire that deals 2d6 points plus the warlock's Charisma modifier of fire and magic damage to any creature that attempts to pass through it. Half the wall's fire damage results from supernatural power and is therefore not subject to being reduced by resistance to fire.
Any creature that takes fire damage from the wall will catch fire, and burn for three rounds - doing 1d6 fire + 1d6 magic damage per round. Burning effects do not stack.
The wall's base damage increases to 3d6 at Caster Level 17, 4d6 at Caster Level 21, 5d6 at Caster Level 25, and 6d6 at Caster Level 28.
The curtain of flame lasts for 1 round per Caster Level before dissipating.
You may only cast this invocation once every 60 seconds.
