You can find him in-game, just search for EducatedFool-1193...
Anyway his build is 2 sets of magic talismans (+15% magic of max magic), 1 more magic talisman (doesn't matter arcane or power) and 1 green mystical.
I'm also maining SoL Eddie, my build is a bit tankier with 2 mystical talismans and -1 magic. But that's not the optimal build at 5* imo.
You could try something I've been thinking of, which should yield an optimal build for SoL Eddie (I'm not using it cause I can't afford to invest that much into new talismans):
Since you'll mostly be using Pilfer(future) since it does AoE and steals and generates a lot of Fury, but sadly doesn't apply effects such as Freeze or Shock, you'll want to use flat magic talismans and basically get as much magic stat as you can and not be that squishy.
(This one doesn't waste set bonuses)
4xHoly Talisman - 3 Power and 1 Arcane (or 4 Power) (you could also use Paladin Talismans, the difference is about 16 magic stat in favour of the Holy Talisman)
2xAscension Talisman - both Ward
That gives you a total bonus of 2306,57 magic stat and a good amount of tankiness.
