Sir, I am going to make a cleric 2, bokor 2, Sadhu 3.
Max OOB right, but make sure your zombies are capped (this will maximize dps and keep you protected while OOB) Run 1-1 str int for zombie damage and OOB dmg.
You won’t need any con for this build. The reason for this is due to the zombie swarm taking the hits.
Basically, you zombie train in and hit about 5-10 mobs. Then go in the middle of the circle and hit OOB and start dishing out the big deeps. The numbers will seem low BUT the dps is actually quite high. 1 Zombie hitting for about 750 dmg and you have 15 zombies+ OOB, thats atleast 45k every 5 sec.
