There were 2-3 more off screen for, plus 2-3 evil eyes. Swarm challenge goes brrr.
I had level 7 plate armour with a stone enchantment, a level 8 vampiric great shield, and a runic blade.
While I could smash them if I caught them, I didn’t have much to charge up runic blade on so the process was slow. Couldn’t bait them to the doors because the room beyond was huge and they would run off.
I used a scroll of rage and that kind of worked. Thankfully my armour took everything they could throw at me, and I only ever really got in trouble if an evil eye shot me unexpectedly from across the room
