I don’t see much point in SPR pally anymore, not after the Zalciai changes… you don’t have anything to gain from very high SPR except for cc resist, which is pretty subpar in Cleric PvM. (iirc you weren’t interested in PvP)
Either way, the char won’t be completely useless - at lv115 you’ll only have so much SPR, meaning there’s time to switch around, and you can use the SPR points as max SP.
Pally1 won’t hurt you too much either, it’s a subpar pick unless you go Pally3 (who shouldn’t go SPR), but it’s not that bad: Resist Elements is there, Turn Undead is there, and Restoration’s good for buffing your heal tiles with some INT. Doesn’t have to be too much INT either, ~80ish would be enough.
If you want to keep going with the pally3 idea, Piyachai's PD suggestion is good. In that case I would switch to INT:CON, CON just however much you need and most points into INT. I guess you can also max Smite for Smite+Conviction combo for occasional burst, but if so I'd also go Inquisitor for God Smash.
imho though, I’d advise you to just drop the pally line - one circle is still fine, but leave it at that - and do something else. In this case, TU will be better for you than Smite, as TU is still decent endgame wherever it works, while Smite falls off pretty hard.
For example, you could use that k1 dip and go INT k3 > dunno > taoist. An INT build + Restoration makes you healbomb pretty hard, so you will have pretty decent support together with solid damage. To consolidate the support role, you can use that “dunno” rank to dip into Oracle, making the party very hard to kill while giving you more SP through Arcane Energy. Kabbalist has good synergy with healbombing too, or you can dip into a damage rank.
