This is outlandish, but are there any powers, feats, items, etc. that allow you to convert untyped damage taken from a hit and turn it into typed damage, be it necrotic, fire, cold, etc?
If I have to ask the GM for it, then I don't want it.
That's the idea! If this is possible, I have just discovered a very broken build. I'll ask the guys over at Char Op for sure, thanks!
