So I've only recently decided to start using one of my tanks in endgame (generally only used my healers and dps so far in the lv 60 endgame) and I've been wondering something about Divine Veil.

Mainly, if I were to do something like crossclass cure, would I be able to activate it myself by using a cure on myself so as to not have to rely on a healer activating it or is a healer activating it the only option?
