Bat Caves

[Ants]

Let's use this thread to compile everything we know about bat caves. Could people who have been inside tell us what it was like? What's the loot? What's the boss? What are some good tactics to get through? Do giant bats give the same materials normal bats do when butchered?

haven't been in one yet but purple rock and if you completely beat one, it helps with credos, i think they said it reduces total quests per credo by 10 but unsure. all from the patch thread
