I did notice a few time lately some item with 100% chance aren’t happening all the time. I only saw this behavior in PvP.
The item I had notice aren’t working like it should are
Jarlaxle rare boots sometimes I get no extra move
Jarlaxle common ring I had him not being restore on the beginning on his turn and I never had that issue with tommus.
Raika boots I was disarm choose to move for some heal and it did not trigger any heal.
