This build is great for beating bosses in high level worlds like corrupted shrine and corrupted cave (and for completing the one-on-one dojo). Speedshot paired with the warrior and precision ring (and vitamin shot) gives it a very high damage output, which makes it great for taking out bosses. Speedshot being ranged rather than melee also helps keep you alive.

Snow globe and pepper spray are for area control because there will always be some other small units that come along the way, so it helps to slow them down so they don't bombard you.

Chicken-o-matic is really important for this build. The fast attack speed means chickens spawns more likely, so that can distract the boss you are trying to fight, which means you take less hits from the boss you are fighting.

Of course, health is important. Vampire teeth pairs really well with speedshot to heal you, especially when combined with the warrior ring and vitamin shot. When you inevitably lose a chunk of health from getting hit by a boss, vitality ring is good for giving you the sudden quick healing to restore your health. Healthy snacks helps you tank the shots as well.

I've taken out bosses without dying with no help from other bots/players on even corrupted shrine using this build. You do need a bit of luck though so that you don't get bombarded by other smaller units, but the snow globe and pepper spray are there to help you out with that. You might have to shift your focus to take them out before going back to the boss.

Avoid summoning totems and invasion portals using this build if you don't have help from others.
