You Stop Him Before He Harpoons Againn
Good work Marivhon. Huh, you're really kicking ass here in the arena. Nice recovery from your previous work as a 2nd level monk. Anyway, you kill the last Kuo-Toan. He disappears, and you guys get your pick of one item from the altar: trident, mancatcher, or harpoon gun.
Pick the mancatcher.Had enough of the Arena for now? Let's say it takes two days and you're all at full with spells. Cross off those rations.
You can fight again if you want, the Fightmaster ain't going anywhere. Or venture out into the big world and see what it has in store.
