Infernal Captain's Fury [Multiclass]
Prerequisite: 11th level, warlord, Infernal Captain’s Pact, Pact Initiate (infernal pact)
Benefit: When you hit a creature under your Infernal Captain’s Curse with an attack, you can grant an ally 2d6 extra fire damage if the ally hits with his or her next attack against the creature instead of making the target grant an ally combat advantage on the ally’s next attack.
Increase the extra damage to 3d6 at 21st level.
