Blizzard responded to player questions regarding Brann’s experience being seemingly stuck. After that level 15 threshold Brann will no longer gain XP from regular Delves. Only Bountiful Delves will grant him increased experience, all the way to level 60.
You can find out more about Delves, companion XP and more in our guide here.
Hello.
At level 15 and higher, Brann only gets XP for seasonal progression from bountiful delves.
We have a hotfix coming that will make this more clear in the tooltip. From level 1 to 14, Brann gains XP from all delves, and then from level 15 to 60, the tooltip will read:
Complete bountiful delves to increase Brann's power in combat during the season.
