Suppress affliction (level1), Pillar of faith is now level 2 --> aoe knockdown + good damage for level 2, dire blessing is a balanced version of devotions of the faithful (that just happens to stack with it), divine mark is great,
shining beacon is crazy good
Priests in general have great fire damage spells at higher levels, this is important because there are quite a number of items in the game that give bonus to fire type spells cleansing flame and pillar of holy fire in particular,
Xoti gets 2 of the best spells in the entire game, in kit level 1 and ESPECIALLY level 7 spells are CRAAAAAZYYYY
I honestly think Priest and especially xoti have some of the best offensive spells in the game rn IN ADDITION to how insane devotions of the "skillful" are.
All healing was done by other characters in my runs (1 reason being how good moonwell is but thats another story). I used priest exclusively for buffing and damage.
There are a ton of things besides devotions that make priest good.
*EDIT*: all that said, if you would give me the choice between a character that has NOTHING except weapons and devotions for the faithful 2 times per combat OR a character that has ALL OTHER SPELLS IN THE GAME! I still would pick the guy who has devotions.
It really is that insanely good.
