Acrid (Unlisted Miniboss)

Acrid can be found in the top-right area of the Sunken Tombs (or rarely the Ancient Valley) level in a cage. After activating the crate, it will open, releasing an NPC, hostile Acrid. He has a good amount of health, but is easy to kill with drones. Once defeated, the playable character Acrid will be unlocked.

Acrid will only spawn in one of the three layouts of the area.

Note: This fight does not despawn any on map enemies and they will continue to spawn during the fight. A way to avoid this is to beat the teleporter and then return to the crate.

Note: The cage has a chance to spawn, so it does not always spawn
