Bronze Dungeon

The Bronze Dungeon is the easiest and 'first' dungeon from the aether collaboration. It appears on the floating islands of the aether, as a tunnel with one or two rooms with 2x2 stables in the middle with chests on top and is mostly made of mossy holystone or normal holy stone.

Mobs
The bronze dungeon houses two hostile mobs. The first is called a sentry. It is a stone guardian the size of a slime, which explodes in the manner of a creeper, but does less damage. These spawn randomly in the dungeon's empty rooms, and do not damage the dungeon floor or walls. Killing sentries yield carved stone and sentry stone. The other mob is called a mimic. Mimics are fake chests that spawn in dungeons that will attack the player when right-clicked. Killing mimics yield chests.

Boss
The boss of the Bronze dungeon is a large guardian stone called a Slider, which instead of blowing up, damages you when hit. It can only move in straight directions, making it easily killed using the main table. The Slider is found in a room in the bronze dungeon atop a large 4x4 table, and is inactive until you hit it with a pickaxe, after which it will wake up and start trying to kill you. It can only be harmed by non-sword tools (pickaxe, shovel...). An easy way to kill it is to make it move to one side of the table, nearly going past it, and then moving back around the table, it will then get stuck, trying to get to you but not able to because of the table. You can then attack it without fear. This will only happen when the Slider is at ground level, which you can get by ascending a ladder to cause it to elevate, then going to the ground and remaining there until the end of the battle. When damaged enough, the Slider will begin to move faster, and its eyes will turn red. The slider drops 7-9 carved stone and a Bronze key when killed. You also earn the achievement "Like a Bossaru" for killing a Slider for the first time.

Although the exact health total of the Slider is not known, using approximately 3.5 full holystone pickaxes will destroy it. If you are killed, the boss will not regenerate any health and will be dormant again when you return (conveniently allowing you to recover your dropped items).

Chest
Once the boss has been killed, the table it was on should fade away to reveal a hidden room with a locked chest in it.
