This gets you
[email protected] and you have to get the rest
[email protected] from torch, anni and ring (plus you can put a couple
[email protected] scs in inventory). slvl 47 skellies. Personally, I max GM and use Iron Golem from low damage Insight to take care of mana problems. This way you can squeeze in a 2nd SoJ. Alternatively, CG is good and you can use the GM points to get sth else, like Mages (hate them) or Bone Armor + Synergy.
Merc: Act2 Nightmare Offensive with Infinity, Bramble and Umed Andariel's
Overall you have fanaticism, might, conviction, thorns, insight. One of the best killing machines out there (competing with an elite light sorc in low player games).
Edit: Obviously max block and I forgot to mention that good glove choices are Trang's and Frostburn. Also, the moment you have IM cast on your swarm of skellies they are toast, so this build will not work well on WSK and CS (sadly, because summoner is my favorite char type). However, if you have the wealth (about 12 HR according to my rough estimate) go for it, it is infinitely more fun than anything else I've played ^^
