If you are wondering what materials the BLE Guild Hall needs for our upgrades, you can go to the Guild Hall Treasurer NPC. He is right inside the guild hall, near the WP in the center of Lost Precipice.

Just click on the Treasurer (the aptly named Esa the Frugal), and you will see the items in the Treasury.

There is a progress bar to show completion rate on the specific item, and you can mouse over the item for more info and mouse over the number under the item for details on what the maximum needed is, and what upgrades the item is used for.

If you want to add to the Treasury, you simply move the item from your inventory into the "Your Contribution" window and Confirm. Esa is frugal and fair - if you try to donate more than the maximum, he will only accept up to the maximum.

Other items such as gold, scribing materials, or other things that you want to share with your guild mates that are not part of the Treasury can be added to the guild bank as always. There is a guild banker in the Guild Hall, too.

We really appreciate everyone's contributions to our Guild Hall!

Lost Precipice continues to grow, thanks to your donations of materials!

A couple of notes:
Esa (the NPC treasurer) is not a good multitasker. He has trouble accepting more than one donation at a time, so I find it best to just give him one thing at a time.

And for Guild Bank - the Stash is used to put in materials for BLE scribes, Trove and Deep Cave for consumables to be shared by all Lions. Reminder: If you have Adventurer rank, you can withdraw from Trove and Deep Cave to combine stacks before depositing, to keep the Trove and Deep Cave nice and organized … (to gain Adventurer rank, just fill out a BLE Adventurer application).

This shows what we have already unlocked, what our priorities are for the next upgrades, and what lies ahead in the future.

So this helps you see what your donations are being used for!
