Zombify should be level 4 for 100% uptime (unless you can be bothered enough to cast Divine Might every single time before casting the skill).
Also, since he has only planned for Cleric C1, there will be no Divine Might so Zombify 4 is actually a requirement.
Krivis should have level 15 Zalciai to make your zombies crit more often, Zaibas can be left at 5-10 for some extra damage or maxed (though it’s currently pretty unreliable) to kill monsters standing on Zombify more efficiently.
Melstis is not really required since you have ± no skill buff effect to prolong, but having it at level 5 might not be a bad choice for future Ranks.
Aukuras at level 3 is enough, get Divine Stigma at level 10 for additional atk/matk through the STR/INT boost. As Divine Stigma will hit more targets at the same time, chances are high that you will be covering the whole CD time with the duration that way (or just use Melstis if you have it).
Bokor should include some level of Effigy. Feel free to leave it at level 5 or 10, but the skill is really great for dealing damage because of the additional damage multipliers ( Hexing attribute = 30% more damage, every 3rd hit =1,5-3 times the normal damage, attribute is cheap until level 80/90).
As you might want to produce some zombies the traditional way (you can also use Zombie Capsules which are going to have their reuse CD time reduced to afair 5 seconds), it’s useful to have some reliable skill to kill monsters on the Zombify AoE, Effigy is your number 1 choice(low CD time and decent damage).
Don’t take Deprotected Zone, the skill sucks at low levels because you have to recast if often, otherwise the defence reduction stacks will be lost. The debuff will also be lost when the monster moves out of the AoE, so it’s pretty bad.
here is how I would build the character:
Daino and Zaibas could be reduced to up Melstis if needed (e.g. if you decide to stack Chapparition cards so you can have 8 seconds of 180% matk).
Hexing can be reduced to increase damageoutput of Effigy, but with a zombiefocus having more mobs affected by Hexing due to the higher level might be your priority.
Feel free to spend the points left on Inquisitor to your liking.
