f key is bound to fire

pausing time or being cloaked gives you 50% harm reduction from mob collisions

no-cloning theorem duplication => down to 42%, but no longer removes 1% on bosses
dazzler => drains 25%->10% energy, and it has a 15% bigger radius
boson composite => only drains energy when you touch shields

'F' key lets you fire, and it can be rebound to other keys
  might be some bugs here, I didn't do much testing
