Maybe a new boss like Ali so everyone have a fair chance? (no Armour/weapons/Buffs)
+1 for a world boss
-More Hp so everyone could join - with a unique drop table, maybe drops tokens for a new store that gives new mid tier equipment (gear and weapons)
-Make it deal damage randomly to everyone in the area (with food spawning around players so they can heal) (not AFKable like ali)
-Reward for players reaching a min damage output and then randomly dropping the tokens among the players
-Untradeable Tokens so it would need every player to grind for the items instead of buying/selling them
