Hi! Im actually doing the same path as yours, with rank 8 coming out. PD will become an aoe-wide debuff spreader. Killing everything by spreading hex and poison before incinerating them to ashes! BURRRRNNNN!!
I highly suggest you max divine might rather than add points for safety wall since you’ll rely on the safety wall attribute anyway.
Im not going for the zombies path tho because imo they suck late game. They rely on STR stat and yet your first ranks rely on the INT stat. You could balance them out but the damage then would be meh. With bokor 2 you can max effigy, hex, mackangdal and samediveve if you’re going INT. If STR then either take another cleric class that could maximize it.
For pd remember that the name itself is PLAGUE DOCTOR. You should spread them legs… I mean… Debuffs. Anyway, I would put higher pandemic. (more monsters affected, more deaths, more money). Also get beak mask because bloodletting alone cant resist higher rank debuffs. Get at least 1.
Good luck and have fun leveling!
