AR dissapearing inside FotM
I had this happen as well.
I have a couple different ascended trinkets for different builds with varying amounts of AR. When I went into FotM, I unknowingly had my condition build trinkets equipped which only had 10AR. Seeing this, I swapped them for the one’s with higher AR (which would total 25). It wasn’t until we got to the Jade Maw and he downed me with one agony burst that I knew for SURE something was wrong.
I had 25 AR equipped in a level 22 fractal; there is no way Maw should have dropped me from full health (I even got of a heal).
I think it has something to do with swapping trinkets with AR out while inside the dungeon.
Hopefully this helps.
You may find at lower levels the AR is descaled down from your max level so it is max for that lvl.
Try at a different level – FoTM lvl 2 and see if you still have AR.
Then try at FoTM lvl 10, 20 – post back what AR you have.
I’m not sure if that’s the issue TPMN, like soakman said this has happened to me on my main and alts swapping trinkets in the fractal before… main supposed to be at 45, alts ranging between 20-30 atm and at various reward levels. Usually un-equipping everything and reequipping fixed this for me, personally.
