what i do:
-at the start of the battle, fire all 4 coins and electric railcoin him, then immediately fire a fully charged alternate piercer and sharpshooter
-then i just use nail gun until 2nd phase
-if my health is low ill pump my pump charge 2 times and go in for the meatiest shot ever
-sliding and then jumping is easier than dashing but i’ll still dash if i don’t wanna go off the map
-at 2nd phase i repeat the process from before but this time use marksman more often
