Wall of Perilous Flame

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. The curtain of flame lasts for 3 rounds before dissipating.
