The Lord Mundus Stone in ESO (Elder Scrolls Online) is one of thirteen Mundus Stones that can be found in Tamriel.
The Lord Mundus Stone gives the player a permanent buff. The buff is visible on the characters stat sheet under “Active Buffs”. You can change your Mundus Stone whenever you want, all you have to do is find a Mundus Stone and activate it. Therefore you don’t need to worry about picking the wrong Mundus Stone because it can be changed at any time.
Every new character starts without a Mundus Stone.
You can only have one Mundus Stone active at a time. There is one exception, if you wear the set Twice-Born Star you can have two Mundus Stones active.
The Mundus Stone buff stays active on your character until you swap to a new one.
You can obtain The Lord Mundus Stone as a furnishing item and place it in your home and use it. This will save you a lot of time searching for the Lord Mundus Stone.
