[Autumn]

After a bit of discussion, you could end up changing Railgun itself to be a skill instead of a spell with a 1 round cooldown, this way Overclock doesn't need to be changed, then you make it so that the skill "Charges" it up instead of invoking, so silence and damage don't stop it easily and make it useless.

Could still even keep the text associated to it charging up too.

How's this sound?
