How to Fish Boss HP & Shots-to-Kill Calculator
Exact boss health pools and how many shots each weapon takes to kill them — straight from the game.
Pick a boss and a weapon upgrade level: the tool matches the boss's confirmed HP pool against that weapon's per-shot damage and returns the exact number of shots needed for the kill, along with what the remaining upgrades cost. If you are deciding between guns, compare the same boss across two weapon ladders before spending — the shot gap is usually larger than the price gap.
Pufferfish has 18,000 HP. A Sniper Rifle at level 0 deals 200 damage per shot, so it takes 90 shots to kill.
Note: the Shotgun damage value is per pellet; the SMG and Assault Rifle are full-auto, so their practical time-to-kill is faster than shot count alone suggests.
All HP values are the exact pools the game uses. Full tables live on our creature stats page and weapon unlock guide. Boss strategy: all bosses.
