I apologize in advance if I’ve caused you any confusion. I put “ok” is because I have an aversion for chaplain xD, though It doesn’t necessarily mean its bad. The reason is most build Priest3 for party-support, yet gave up at the end by getting Chaplain class which is a personal-buff.
All clerics need SP regardless of their builds. You should be ok, and may even need to add spr later. Druid is more of a PvP as i’ve been seeing.
If it is your first char, I’d recommend getting a Support-Oriented but still be able to solo type of build. In that regard C2-Priest3 is good to have, and you’d need to pick up an aoe skill along the way (maybe Krivis for lightning?). As for other classes:
Krivis - Buffcount, DPS
Paladin1 - Restoration, increases heal
Dievderby - Utility
Oracle - Chance/Utility
Plague Doctor - Debuff/Utility
Pardoner - Debuff/Scrolls
Kabbalist - HP Buff
Monk/Sadhu/Druid - DPS Classes, sry can’t comment on these as i dont know them well enough.
Better choices would be Oracle/Kabbalist/PlagueDoctor, though that would be just my preferences. With whatever you picked, I would still recommend a rank2 of cleric for convenience. Although it is not necessary.
