The Bank is where you stash everything you do not want to carry, and it matters a lot for gathering because most items do not stack.
There are two banks, so use whichever is closer. One sits in the town cluster, the other out west by the mines.
| Bank | Location (x, y) |
|---|---|
| Bank 1 | 6960, 5296 |
| Bank 2 | 10672, 5360 |
The big rule for gatherers: ore, logs, bars, gear and gems do not stack, so each one takes its own slot. The only items that stack are the totems and the Jade Talisman: Experience Totem, Jade Talisman, Damage Totem, Evasion Totem, Critical Totem, Earth Totem. That is exactly why a mining or woodcutting run fills your 36 slots fast and sends you to the bank, which the XP Rates calculator already builds into its rates.
