I find the question quite annoying tbh because both have their merits. But if you must absolute get sadhu at r4 then go cleric2.
Just keep in mind that krivis2 is far better for leveling, but it will drastically limit how often you can use oob prior to rank 5 or 6.
Technically it’s better if you can party up 24/7, but the party mechanic can suddenly stop working entirely…
Cleric2 in contrast offers really good protection for sadhu’s so they can stick with oob. But since the divine might nerf it has been very annoying to level.
Also not all sadhu builds will need cleric2, but it’s still great to have.
.
PS, fade combines well with oob because it’s auto attacks do not end it. Meaning enemies will attack something else nearby like a companion while it is active. (or at least it did, i hope it wasn’t changed) Definitely not going to work in pvp though.
