Build for max efficiency for blessing so you can spam it. You'll need 150 power strength at minimum to [Reach] the cap for blessing. You don't need range since Blessing scales off of affinity range.You can change the aura polarity to slot in what you want. Arcanes use what you want. Nullifer is always a solid option if you don't have [Harrow] in your squad. Your job as [Trinity] is to get lures, charge them, and heal them when necessary. Use madurai school for void strike and unlock [Blaze] and metoric dash to charge lures without wasting void strike.
