Hidden Cavern

General
On each side is a locked door that requires a key to open it. The Bone Key for the east side drops randomly on the banderlings. The Glittering Key for the west side drops randomly on the drudges. If you get to close to the rock piles it triggers additional spawns. This dungeon used to contain Harraag, Banderling Champion until he was kidnapped by the Virindi and turned into the Prodigal Banderling Harraag.


 * 1) The cavern is split into two main sections; heading left at the split leads to the western Banderling inhabited section and heading right takes you into the area populated with Drudges.
 * 2) * Warning: There are dispel traps found just after you turn left or right at the first split. They can be jumped over safely (see map).
 * 3) Each section is full of that area's creature, and also piles of rocks and stones, which summon even more creatures if you get too close.
 * 4) To unlock the door in each section you will need the Bone Key (retired), dropped by Banderling Champions, and the Glittering Key, which is dropped by Drudge Seraph Mystics.
 * 5) Once you reach Scrum's lair, you can talk to him and he will force you to kneel, he doesn't appear to have any other purpose and doesn't give rewards or quests.
 * 6) The Obsidian Shard found behind Scrum's throne can be translated for lore.
