Dungeon Duels

So I made this map in 3 hours for a youtube video, so it's not well polished or anything. So the goal is to beat the boss in a dungeon, you must do this by killing a few different mobs which can drop gear and even dungeon/boss keys. You can play this as pvp, co-op, or solo rounds are usually pretty quick regardless of how you play. It should be pretty simple to modify the map if you want since it's so basic you can do things like add a spectator button, give regen, and set gamemode to all players when the dungeon starts, things like that.
