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
Yeah, actually the wand of corrosion excels if paired with any type of enemy-aggro that beckons the enemies towards the corrosive gas. The sad ghost is an example, paired with its immunity to gases and your ability to control it makes it one of the best pairs with the wand. The living earth is good too, it just doesn't have as much hp.
