I got this ring of force +2 on level 4 in a crystal chest. The imp down in the Dwarven city gives you another ring of force +3. Dumped 12 scrolls of upgrade on the rings, (and 1 on a wand of disintegration found at +1 and 2 on a plate armor). They deal 25-156 damage! Awesome.
Seed was ZVW-WWG-QMX.
Love finding them early. It’s like finding a tier 5 weapon you can use instantly.
