Since you are doing the tests could you try it with these parameters?
Fight the goblins at the top floor of Selune's temple ruins. No hiding or cheesing.
Party consists of Wizard, Rogue, Warlock and Cleric. Cleric: Autoattack and Cantrips Wizard: Only Cantrips Warlock: Eldritch Blast (OT 36% hit rate when in front of the target?) Rogue: Sneak attacks, off hand strikes and auto-attack
This was the setting where I saw the phenomenon. Like I said, before the 2 bug bears destroyed me I had cleared the entire courtyard of goblins with little to no difficulty. Something happened up there that inspired this thread.
It is an early access afterall. Things are not working properly all the time.
