I finally managed to do the Bank.
You can now deposit up to 40 items per character, and you can deposit your gold.
It’s good to deposit gold, because there are thieves in the dungeon and they steal a percentage of the carried gold, so the more gold you carry, the more gold they steal.
There is an option to party deposit gold, what this does is that it takes all the gold from all the other characters, even from their bank, and gives it to the current character. These is good if you want to identify a legendary item which is too expensive(identifying doesn’t work yet).
After Party Deposit:
Next on list is the dungeon, I will add, water(characters will drown slowly if they stay in water for to long), holes(falling damage), traps, secret doors, teleporters, etc..
