[4E] Low level encounter powers as at-wills?

[Yakk]

Good point.

At level 13+ you start replacing encounter powers. Instead of level 13+ powers replacing level 1 powers, they are added, but they deal 1[W] less damage.

Powers that only deal 1[W] are increased in level by 5, and left at their current damage.

Non-weapon powers are dealt with on an ad-hoc basis.
