the only attacks that can be reliably blocked are melee attacks so if you’re mostly taking damage from range that would be why. so many projectiles and projectile-based spells cannot be blocked it’s a bit ridiculous (previous observation).
the base fleshwarped enemies that throw fire/aether-balls that get spawned from the big aetherial guardian thingies - can’t be blocked. those ranged tentacles that pop up all over malmouth - can’t be blocked. the list probably goes on but that’s what was apparent when i picked up my block-based char again. might make a bit of a stink again in the next playtest about this.
edit: since i had the suspicion and just got to the end of forgotten gods: can’t block any of the koorvak servants projectile attacks, which on top have way too high physical damage still (seemingly didn’t get nerfed when we lost physical resistances) and they can’t hit you above a certain max range but won’t try to get closer.
