It says you can take an at-will power. While this might be taken to mean "Any power that can be used at-will," it means the four at-will powers that each class can choose from.Deverash said:Does the half-elf feature let you take any power that can be used at-will, or any At-Will Power(which is a category of powers, along with Encounter, Daily and Utility)?
For example: You can't take Mage hand, Lay on Hands, Divine Challenge, etc. etc.
I mean, you don't even get those when you multiclass! There's no way a half-elf can get them for free.
