Lycanthropy skills benefit from Blessing as well but, as you said, line buffs don’t work because they’re skills as opposed to auto attacks.
Pretty much. Feral Priest isn’t the most DPS oriented route. Instead, it’s more of a support/DPS hybrid. Blessing, Revive, Ressurect, etc. form the core of the support side (Along with Safety Zone, Sterea Trofh, and Divine Might). Carnivory, Exorcise, Cure, and the Lycanthropy skills serve as DPS.
For a more damage oriented set up you can go Cleric2 -> Dievdirby -> Sadhu2 -> Druid3
Full SPR. You could throw 50 or so points into CON if you really feel the need but it’ll make Blessing less potent.
As for skills, the most important thing to do is max Blessing. Beyond that, the same general rules apply. I wouldn’t bother with Aspersion or Stone Skin. The changes made them rather useless compared to what they were before.
