Power Adept

Prerequisite: 4th level, the ability to cast force or tech powers When you gain this feat, choose one of the following damage types: acid, cold, fire, force, lightning, or necrotic. Powers you cast ignore resistance to damage of the chosen type. In addition, when you roll damage for a power you cast that deals damage of that type, you can treat any 1 on a damage die as a 2.

You can take this feat multiple times. Each time you do so, you must choose a different damage type.
