Not unique to priests. “Additional” healing is only needed when you “need it”. Props if you understand this.
Immunity is granted after death and does NOTHING before you die.
Requires the recipient not have pardoner buffs as priest buffs can’t overwrite them.
Again, does not require the priest to begin with. In addition the additional stats become irrelevant the more people start getting better gear. C.atk? W.atk contributes WAY more to damage. Atk speed? Only relevant to AA builds as “faster execution” still results in the same dps. B.pen? You have way more than enough pre-monstrance at the significant lvs of DEX.
In fact the build could do with priest1 and he would have free [monstrance] (and 1 rez).
All but 1 perk of being a support priest you mention are there without the priest present.
@yodish92
I think because cleric 1-3 can heal, that makes priest heals a more expensive opportunity cost. I’m also not actually suggestion to use [heal] offensively for a build that wants to focus on “support”
To address your concern directly, I’m trying to argue that there are better options to priest for support. Seeing the OP wants a chaplain though makes that point moot as a suggestion hence I followed with the conditions that maximize the use of what priests do offer “counter to death” (to put it simply). See all clerics counter damage, but only priests can counter death (and the effects of death - no buffs).
