I was in Driftwood, just on the other side of the bridge fighting the flying poison void insects to save the mother from the voidwoken. I summoned an Incarnate Champion (who blocked the doorway to the house like a jerk) and to my dismay, I noticed that when I went to attack the bugs with him, he would slam the ground and not connect with the enemy. I tried giving him a ranged spell, and that ignored the enemy as well. I didn't get a message that said "attack is blocked", or anything to indicate why this would happen. He simply couldn't hit them. No damage numbers, no miss text. just ... didn't work.
