Bat Cave Dungeon 2

It’s an Uncommon dungeon, so each of its Bats comes out Blue at 40%, Yellow at 30%, Red at 20% and Green at 10%. Some waves are set to Red, Green, Purple and Boss whatever the rarity. Wave 11 is Rare instead, which is where its Purple ones come from, as the Waves table below shows.

Its waves end with a single Boss Bat at the dungeon’s highest level.
