A vault is a space for players to store items in. Personal vaults can initially be bought from Gomald for 500 gold, and guild vaults can be bought for 10,000 gold. All vault prices can be reduced if wearing and showing a Medal of Gratitude.
There are different stages of vault size, each new stage purchasable by increasing amounts of gold or $10 from the Aberoth Store . There are a total of 16 stages in vault size, with prices ranging from 500 to 600,000 gold. Each stage increases the size of the vault as well as the brightness. The price for the next vault size is approximately the price of the last two added together. Buying a vault and upgrading it to the final stage costs a total of 1,671,000 gold.
Beginning at the 14th stage upgrade, the player has access to a room in their vault through a door that will have the first letter of their champion name on it. The vault owner is the only person able to open and close the door. At the 16th stage vault, the interior brightness is 85% of that of the town / outside in daytime.
Other players can be invited into another's vault with the command "invite [Name]". Invited players are unable to take items from somebody else's vault, unless they are trusted. To trust someone else (allow them to take items from your vault), the command "vaulttrust [Name]" is used.
Guild vaults are purchasable by any member of a guild. They are upgradable like personal vaults. The starting price for a guild vault is 10,000 gold, while the 2nd stage upgrade is 20,000 gold, the 3rd 35,000 gold, the 4th 50,000 gold, the 5th 75,000 gold, and so on.
Access to guild vault doors (starting with the 5th stage guild vault upgrade) can be restricted to guild members of a specified rank by using the doorrank <rank level> command.
