Yeah, I just don’t see much sinergy between Priest and Bokor. From what I see, Priest’s damage comes from autoattacks, with all the boosts it can give to themselves, so I’m not sure it that fits a full INT build such as yours.
In the other hand, after researching a lot in the boards, I found a build used in kTOS that is Cleric > Priest c3 > Chaplain > Krivis > Plague Doctor that deals heavy “melee” damage using INT. It works by maxing out Aspersion and Aspergillum at Chaplain, so that each autoattack splashes your lvl 15 Aspersion in the face of enemies. Together with Blessing and Sacrament from Priest it deaks neat damage with each mace swing, while being very sturdy thanks to Safety Zone, Stone Skin and all the heals you have.
The build seems very neat, if you have interest on it I could share it with you. It works as an INT melee damage dealer that is also an amazing support, so that’s an interesting concept. But I think that the build is pretty hard to level before you get to Chaplain. Anyway, it fits what you were expecting out of Chaplain.
To sum it up: The way for Priest to deal damage with INT doesn’t have good synergy with Bokor, since Priest skills don’t work well with it as far as I can see. If you really want to go for Bokor though, you can substitute Krivis in the build I mentioned above and go for it, and focus on Effigy spam. But I’m having a hard time seeing your single Priest circle being more usefull than, say, Cleric c2 (10 tiles of Heal make a huge difference when compared to just 5 tiles).
I’d advise you to stick to the Chaplain plan and go for a more damage-oriented approach, or leave this character in the backburner while you level something else, waiting for balance changes. Who knows, maybe they’ll nerf Stone Skin.
