The majority of the "damage types" achievements are glitched on the Game Pass version of the game.
- Tons of enemies were killed with long/greatsword and axes, but the achievement for slash damage never unlocked.
- Psychic damage unlocked the Piercing damage achievement,
- Necrotic damage achievement unlocked on a bludgeoning damage.
- Poison damage directly from spells aren't counting.
There were others that i don't remember quite well, but i think this report is enough for you guys take a look at this problem.
