Does what it says on the tin.
UPDATE : Insanity Value skill went from 50% to 100%, like Overkill Buffed it.
I always thought that Maniac Hysteria Stacks drained too quickly and updated too slowly.
So this mod simply changes the values so that it takes 12 seconds to drain, and 3 to update.
Please send me a PM if this seems a bit too powerful, I'll get around to adjusting values once again.
