Mines was in Titan Extreme. My protect is on a seperate hotbar so i have all my must have during battle on my first hot bar (cross hotbar ps4, press r1 to change hotbar).

So, i cast stoneskins/protect at the start of the fight. Ran in, started healing. Or i THOUGHT i was. Realised nothing was happening.. only realised it too late when the group had wiped because i wasn't actually healing, being on a completley different hotbar at the time lol!

Needless to say the group I was with was questioning why we wiped, i /shrug and say i don't know, we continue to kick his ass xD
