So for a while now when I've been questing, whenever I use AOE's (mainly tempest) sometimes it'll only do half the amount of damage to one mob that it will do to the others in the battle. This also happens in boss battles. Is this a bug or a mechanic in the game, like I said it's been happening for a while now. To give an example I was in Mirror Lake earlier and during the Starburst Spider fight I used temp and it did well over 5K to 3 out of the 4 but the other one it only did around 2.8K, even though it wasn't shielded.
I've had that issue but with Snack Attack. However, on that spell, it usually only crits correctly on the enemy you click to move the negative charm to.
This is due to each mob now rolling for crit block independently of each other, and the reason it's not obvious is due to the bug with enemies not showing block when they actually block a critical
