Fuck charged shot, we're an owl with a gun. Goal is to get stacks with owl by upgrading it to T3 instead of buying items for it. If you're not getting stacks on it you stay gun and go glass cannon (which you can get stacks for with owl) If you do get stacks then you'll get Merc Mag which scales with spirit while synergizing with the gun items you've bought. Boundless will then give you extra spirit power based on how many stacks you've accumilated.
