This is for PvE, i didn’t put in the skill points yet. I’m playing with a friend, so I wanna play a healer to help them out. 
You don’t really seem to have much healing thou… only cleric 1 and priest’s mass heal is okay but not that great at healing.
Also, I’m not sure I would place a sadhu 2 in that build, maybe i would rather go for druid 2 since you can pick chap at rank 5…
This way:
Well if you want to pick sadhu 2 with chaplain that’s okay, but I would personally pick chaplain before sadhu to make your leveling life easier.
Just like this. 
How would I do skill points for this? Plus the stats as well.
May I ask why you chose those classes ?
It’ll be better to help you with the skills.
You probably can drop Chaplain too ? Chaplain is mainly good for the extra damages, but if you play with a friend and will mainly heal, it’s a bit useless.
You could take Cleric 2 instead or something else.
Cleric’s Heal scales with INT (but not too much), Priest’s Stone Skin scales with SPR, Mass Heal with both INT and SPR, and Sadhu scales with INT.
So you’ll have to make choices there… You could still split it between INT, CON and SPR, but then it means you won’t be great at anything, just average at everything.
I may suggest picking Priest1 at R2, so you have Blessing to help you out with lvling. Afterwards you can pick Cleric2 at R3. Flying mobs tend to cause alot of trouble to Clerics that dont have STR. Blessing atleast makes dealing with them alot easier.
I wanna heal, I could go Cleric > Cleric 2 > Priest > Priest 2 > Priest 3 > Sadhu > Sadhu 2
I was trying to pick good classes for a support build, I don’t wanna remove Priest and Sadhu.
You won’t need Heal 10 until much later… So I agree on the Cleric > Priest > Cleric > Priest > Priest. Can even go Cleric > Priest > Priest > Cleric > Priest.
First dungeon is at level 50. By then you’ll be Rank 3 already. Second dungeon is at 90, you’ll be rank 4.
Leveling as a Cleric is tough, so Blessing makes it much better. Although you could pay for it in shop, but if you’re gonna go Priest, might as well level it asap too.
You like Sadhu for the DPS ? Since it’s not a support class at all.
Cleric skills are pretty simple to choose: Heal 10, Safety Zone 5 (can go to 10, but it lasts 20s no matter what, so it’s not necessary), Divine Might 5, Fade 1 (situational, but nice). Cure is a nice damage skill + cures negative status effect, so I’d say at least 1. Deprotected Zone scales on SPR and the boss needs to stay in its area of effect (tiny circle) so it’s not great, but you can take it to level 3 for the attribute.
Priest skills are more tricky, they will depend on what you want to do.
Resurrection at least level 3, Revive 10, Stone Skin 5.
Then you choose for the other skills what you like/use more.
Mass Heal I’d say either level 1 or 10. Maxed it’s amazing but it’s a heal that can be dodged by your targets, so you can’t count only on it. At level 1 it’s 10%, not incredible but can be enough when Heal is on cd.
Blessing if/when it’ll get its patch will scale on both INT and SPR. At least level 3 for the attribute (which matters the most with the scaling, so you probably don’t need to max it.)
Aspersion only increases your PDEF. It’s not bad, but I wouldn’t level it too much if you don’t have many skill points left.
Sacrament would be level 1 for the +Holy property damages, but the extra damages given isn’t good enough to level it more.
Monstrance is mainly good for the +DEX. But it eats a buff slot, so you can’t use it all the time. Situational.
The skills that matter for Sadhu are Possession, OOB and Prakriti. Explosion has a really low animation + it sometimes bug your toon, so it’s meh for now. Vashita is channeled and you can only use it when you’re out of your body so usually it’s not a skill you use that often.
I’m going Cleric > Priest > Priest > Cleric > Priest, the last two ranks are open for whatever is place there.
I re-did the build for a more Support way.
Would this work for Support?
