I usually pick up fifteen when I go.
You will need these before we set a time to go.

If we had a lock picker and a guide for each bell part, we could turn the parts out pretty quickly.
One part needs no guide, as the chest is in an easy to get to place. w00t!
The other two need guides (Fork Hives).
So, we need volunteers:
People that need bells (bring a lockpick)
Lockpickers to open chests
Guides for East Fork and North Fork Hives. Guide people thru the dungeon. East hive will be more work than North.
