Guild Vault is an inventory storage space available to a guild that has researched Guild Stash upgrade. It can be increased to include as many as 250 slots. Guild members can access the vault by speaking to a Guild Banker in any of the major cities (see below) or activating a Vault Transport upgrade.
Access to each section of the vault can be limited by adjusting the permissions of the relevant member ranks. You can restrict which roles can deposit and/or withdraw items from each of the available Guild Vault sections.
