Additional Updates

• Restored air movement.
• Corruption in Neon Underground, growths in Q'Bthulhu's Realm, and loot stacks in Flakbeard's Hideaway should never block monoliths nor entirely obscure path arrows.
• Delve adventure rewards have been adjusted:
  • "Defeat Delve Bosses" now gives 5, up from 1 (and now actually requires you to kill 3 bosses instead of just 1).
  • "Rescue Captured Geodians" now gives 3 caches, up from 1.
  • "Corrupted Memories" now gives 5 caches, up from 1.
  • "Shadowy Soul Vault (Depth: 25+)" now gives 3 caches, up from 1.
  • "Craft a Light Banner" will now complete if you craft one of the new Enchanted or Enshadowed Torch Mods.
• The "Complete 75 Private Delves" Badge has had 1 additional Ornate Pressure Locked Cache added to its reward [I THINK players will get the reward granted to them, but I'm not 100% sure]
• The "Complete 100 Challenge Delves" Badge has had 2 additional Orante Pressure Locked Caches added to its reward.
• The "broadcast message" banners have had their drop rate adjusted downward.
• The Geodian Boulder merchant has been split into two merchants: one which always sells caches and one which always sells recipes.
• Pell is always present when you defeat a boss. Occasionally, though, Pell will be joined with a Rescued Boulder Cache Trader. As your Depth increases, more rescued Geodians will become available:
