Sadhu - PD - Krivis is pretty good on paper if you’re not using Sadhu vaivora and replaced Crusader for Sadhu. OOB’s arts allow you to summon multiple clones that can use your spells, so just pop all of those and then start spamming Krivis’ Piety + debuff stacking/burst combos.
Sadhu - PD - Druid is another option if you’re looking for 10-15 seconds burst window with 123.3% critical damage sterea trofh + Sauk set effect. (Also if you don’t need anymore accuracy/block penetration bonuses)
