Right now I don’t think it’s that good… doesn’t offer that much for just taking 3 ranks of it for Barrier which is like the best ability for Paladin.
Specially since you can simply buy scrolls of Barrier from a Pardoner so you don’t need to waste 3 ranks in Paladin, besides Paladin needs STR to deal dmg, and healing and skills from Krivis needs INT (SPR if you also want to get some Priest Ranks for buffs) so it doesn’t go that well, you can’t really have nice dmg with Paladin while having good Healing or vice versa imo.
I’d suggest if you want Dievdirby and don’t want to follow the typical healer build (Cleric C1 > Priest C3 > Chaplain > Cleric C2 > Plague Doctor) I think something like this would be good:
Cleric C1 > Krivis C1 > Dievdirby C3 > Cleric C2 > Plague Doctor
That’s like the other variant of a really nice support build imo, more buffs from Daino, really nice statues from Dievdirby, decent heal with Cleric C2 and status ailments cleanses with PD, pretty much all you will need if you don’t want to go with the classic one/don’t decide to go Paladin at all.
