Hellbound Heart

Heroic Tier
Prerequisite: Warlock, Infernal Pact
Benefit: Whenever you spend a healing surge, you gain resist fire equal to 5 + one-half your level and a +2 bonus to your next saving throw before the end of your next turn. If you already have fire resistance, you can instead increase that resistance by 5 until the end of your next turn.
