If you aren't running enough res to resist most debuffs, one of the various blessings that activate on receiving a debuff is probably best. Otherwise, the aura blessing or phantom touch.
I plan to be running a ton of resist.
The aura blessing is what I'm leaning towards. Can you help me understand the healing blessing and restoring Max HP, which fights or bosses reduce Max HP?
And yet, they did nothing to the actual most broken PVP blessing => Polymorph. This blessing is so whack, it killed options for dozens and dozens of champions, making PVP idiotic. Everyone putting 60 buffs on their team and debuffing is a super risky strategy versus 4 polymorph teams.
If there was a nerf to be done to any 1-star blessing, it was to that one.
