Editing Dragonfire Adept

Dragonfire adepts are like warlocks in that they get invocations and a new form of attack, which is a breath weapon. Unlike warlocks, they don't have to blow any invocation slots to change their main form of attack, because they get breath effects which are basically like blast and shape invocations except they can't be traded away as you level. While DFAs share a few invocations with the warlock (Walk Unseen, Voidsense and a few others), their list is otherwise unique to them and they have some goodies that warlocks just wish they could have.
