Battleship's New Formula

Try using the ckpq totem poles in the test of agility since there's no randomness to them, and you can control exactly how much you get hit for. First use big potions first like reindeer milks to see which 5k multiples the hp lies (like 100k-105k or something), then narrow it down from there with smaller and smaller potions after you damage your ship into that interval again (100k in the example).
