My guess would be INT and spri… also some dex?
I think it will be something like this Int>Spr>Con, I’m not sure why Dex would help.
Int will help with damage and heals.
Spr will make sure you have SP to cast those skills.
Con will help you survive a few hits. I think every class will need a little Con because even if you dodge 80% of the hits the 20% that will hit you will kill you easily, specially for boss and PvP.
what are the best stat points to make a doctor?
There are a few options stats build for Cleric.
If you’re planning to play full support role, INT + SPR are your primary stats overall; mainly for Deprotected Zone and Zalciai + provide a minimum damage along the way.
CON is useful as well, but this stat is not necessary as long as you know how to position yourself in the battle field. You are meant to be a back liner, not a front liner.
On the other hand, if you’re planning to play both PvE and PvP; mainly high tier damage and half support. You should be pooling all your stat points toward INT.and CON
Additionally, based on your skill build you should avoid maxing out Divine Stigma and Monstrance. The reason to that is Divine Stigma buff does not last long and it is way better to pool your skill points toward Daino to extended the buffs limited for maximum late game capacity.
Monstrance is only useful if you have a pure DEX’s user; Paladin/Monk, Swordman, Archer, and etc… (Physical Classes Based). It is best to leave it at level one and pool the rest of the skill points toward Mass Heal and Resurrection.
