I can’t say for Sadhu circle 2 skill though because I don’t have one.
For PVE…
Safety zone + OOB > Spam spirit normal z attack have attribute for 10% chance to give Def down to target > use various skill from other job you have with your body because monster will talk toward your body anyway and they’ll be in you body skill range.
You can also use OOB as fast warp (Prakriti skill) to escape or reach target.
OOB move speed and atk speed is very fast. One attack hit will do damage 3 times. attack can also spread to nearby target. Only problem is you have to be careful to not let your body get hit or spirit will return to body. While use OOB your Def will be decrease too so it’s hurt.
