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?

I actually have no problems with this change should it happen. Seems like the most elegant way to not destroy the practical use of the bot while keeping its charge up weakness intact. It should also immobilize itself probably should it happen to be changed to a skill.
