Cleric C2 > Priest C3 > Chaplain > Miko > Inquisitor Full SPR, synergizes pretty well between Miko-Inqui combo but that’s it imo, clap is useless for you, hamaya is okay-ish though kinda hard to land and Kagura is only to buff your melee pals or together with Wheel, which you’re probably gonna use it only for bosses, unless you don’t mind wasting lots of Wheels which cost 1000 silver each for each cast.
Cleric C2 > Priest C3 > Chaplain > PD2 Full SPR, A more supportive variant which however has the ability to solo and even farm pretty efficiently, brings you Black Death Steam which together with Pandemic you can clear entire rooms of mobs in a dungeon or HG, Healing Factor which makes you stupidly tanky and it’s kinda impossible for you to die unless you take absurd amounts of dmg, also debuff cleansing can be helpful in some scenarios.
Cleric C2 > X > Sadhu C3 > PD2 Full INT, it’s not a support anymore, you turn into an aoe dps monster with Black Death Steam, Possession and Astral Body Explosion, you can fullfil the role of an aoe dps in a party pretty well, specially when you’ve a Cryo on your team, Possession into all the mobs in the Ice Tree it’s satisfying, however like I said, this is not a support anymore, you’re a DPS now kinda, the X can either be Bokor, Cleric C3 or Diev, up to you.
Cleric C2 > X > Sadhu C3 > Miko > Taoist full INT, ditches PD2 for more support-ish playstyle, Taoist compliments Sadhu pretty well because of Dark Sight allowing you to use OoB without getting interrumpted, we still get Hamaya for some AoE which is nice and we can boost our melee pals too, X same as before (personally for both I’d pick Diev, reducing Transmit Prana downtime from 20 secs to 5 secs it’s a huge deal imo).
Those are the build I could think of that might be interesting to you, I’m using the 2nd one and loving it so far.
The full INT/SPR is personal opinion, if you want you can pick some CON or even some SPR for the INT variants for SP, but it’s all up to you.
