I would suggest you look at the Multipower for your freeze rays. Buy it with the OIF Limitation (which is an Obvious, Inaccessible Focus for a -1/2) and that will make it cheaper. Each power you want will be one of the slots in the Multipower. One for an Entangle, one for your Change Environment, one for a Blast to do some damage, perhaps a slot with a Barrier to make a ice wall. Just a thought for that last one. That can apply to a pair of freeze pistols or a rifle and pistol as the special effect of the power.
I dont thinking quite follow how multipower works.
I think I pick powers as slots, and assign my pool of points between them.
Can I redistribute points at any time?
