Remove monster Invulnerability
Yes this is a very big issue for me, all annoyance causing (and presumably unintended) bugs aside I don’t think it’s right or fair for monsters to be able to be invincible because they can’t attack you. If you are on a cliff attacking something and they can’t attack you that is smart positioning on your part and to be punished for that isn’t right.
Monsters should instead go oh I’m being attacked, can’t attack the attacker so lets move out of range.
Also in the same vein I’ve had some instances where I was in a fight, the monster was attacking me as well and then like it had decided it was bored or done with the fight it ran away and regenerated to full health even as I was still attacking it. I’m not sure if programmatically the two issues would be connected but from a player standpoint it seems they are.
