this, with a 4:1 Int/Spr build, with the extra points in Con.
PD isn’t absolutely -required- but it’s certainly not a bad choice either.
it is painfully slow to get to 125-ish so you can finally become chaplain. it isn’t -hard- to get there, just slow, because even with Blessing you deal only moderate damage. but you also have your own heals on-hand, so there should be very little that actually slows you down, either. and then once you do hit chaplain, suddenly you’re doing monstrous melee damage with aspergillum.
MUST haves: Sacrament (you need it for Last Rites), Aspersion (for Aspergillum), Blessing (so much damage when you stack for # of hits). Cafrisun armor (it gives you an extra hit-line with each attack).
always keep Blessing and Sacrament running (you can buy them in town too, but Sac will last an hour, and Bless only ~10 minutes because of the 150 hit limit).
one you hit chaplain, also keep aspergillum and Last Rites running as much as possible.
melee hit (+sac holy +blessing +LR holy) [and any other elemental damage bonuses]
+sacrament Additional Damage hit (+sac holy +blessing +LR holy) [and any other elemental damage bonuses]
+Last Rites Additional Damage hit (+sac holy +blessing +LR holy) [and any other elemental damage bonuses]
+Cafrisun Additional Damage hit (+sac holy +blessing +LR holy) [and any other elemental damage bonuses]
+Aspergillum hit (+sac holy +blessing +LR holy) [and any other elemental damage bonuses]
if you have a Pyro in the party, you’ll probably also have…
+Enchant Fire Additional Damage hit (+sac holy +blessing +LR holy) [and any other elemental damage bonuses]
and every hit-line also will add a bit of Fire damage from the Enchant Fire.
…if i knew of things to give even more hit-lines i’d add those too, but overall it rapidly stacks up into an -immense- burst of damage per hit. it’s hilarious, each new zone i smack a monster a couple of times unbuffed for comparison, and barely scratch it (like 20 hits to kill)… then i buff up and 2-hit or 3-hit the next mob.
additionally, on top of all that stacked damage, you get the other nice benefits like throwing your own heals whenever you need them (and as an Int build primarily, they’ll be quite strong)… Safety Zone… even Cure’s tiny damage rate will take all that stacked damage and become something noticeable. Mass Heal, Stoneskin, etc…
Once you have the “core” of the build done ( Cler > Pr3 > Chap)…
Rank 6 is pretty open, and would make a good spot to push in another rank of Cleric if you feel you need more Heal tiles. you could also add Divine Might, and boost your Safety Zone.
Plague Doctor makes a great addition at Rank 7, with a strong combination of Support and DPS.
if you don’t like either of those choices, you can add nearly anything else that you like to the build.
Krivis for the Lightning AoE, and Daino… Diev for statues… Paladin for heal aura and smite… Pardoner to earn money while you’re sleeping (since you have all the buffs anyway, right?)… Druid for a different style of DPS…
