Yeah, it was just as I feared, lol. Attempt #1 failed. All out of juvs so I S/E'd. They still hurt a damn lot even though my lightning resist was maxed.
In a new game, I ran into a crazy area full of several packs all together in one spot. Result:
Guess what I ran into? A pack of souls with conviction aura
But instead of S/E'ing, I decided to shop for a scepter with Light Resist aura. Only took me two attempts @ Ormus
