Which Defensive Infusion?
If you got the money, use omni infusions, either of the following:
- Versatile Mighty Infusion (power+5, agony+5)
- Versatile Precise Infusion (precision+5, agony+5)
:3 Failing that, use the vitality ones, I guess, since the more toughness you have the more likely mobs will go after you instead of teammates. :o
