I've created a Storm Sorcerer using Character Builder and I've got a question about "Storm Soul". It is described in "Class/Other features" section and states the following: "Resist thunder and lightning and pierce thunder and pierce lightning with your spells. End your resistance to gain +4 to all defenses."
So, I've got several questions regarding to it:
- Where did "Storm Soul" come from? Is it just a benefit of storm sorcerer build?
- Do I understand correctly that I can get rid of resistances and get +4 to all defenses till the end of encounter? Isn't it a kind of imbalance?
- If yes, can I switch resistances/defenses whenever I want or there are some restrictions?
Could anyone please help me with this?
