Bank
Description
The treasure trove of the guild and therefore also the centre of its growth. Donation are guarded very carefully here. With every expansion of the guild bank, a larger vault can be built that stores a further 2% of guild gold.
Two dark figures guard the entrance and eye up every visitor to the guild bank. You definitely do not want to start a fight with either of them. Inside the bank, lots of grids prevent unwanted intruders from entering. A bearded merchant with a funny look stands behind the counter. With Roman correctness he documents every donation in the donation book and fills the vault with [Amount of gold in vault]% of the guild gold.
The bank serves the purpose of storing and distributing the guild's gold. People can donate their gold in favor of the guild here by using the Donate button inside the bank. All the donations can be viewed in the Donation Book tab. Increasing the building level only provides better % of gold in the vault. Gold that sits in the vault is % of the total gold in the guild which is protected from guild attacks and cannot be looted. Most guilds don't tend to expand the Bank more than Level 10.
