With the change in Leech effects those properties aren't "must haves" like they used to be, but still very effective as long as your dealing big hits. The top properties to look for should be Slayer/SSI/HCI/Balanced(if your a pot chugger)/Leech Effects in that order.

Your suit needs high LMC and MR with near max resists, +HP is bonus.

My stats ran (this was before the +5 Stat bump and with a +15 Scroll only):

85 Str/ 90 HP(*Higher HP (and Str) is suggested as some things still hit hard with good resists)
125 Dex / 140+ Stam(140+ with items depending on what I wore)
30 Int / 60ish Mana(was Elf and items added mana)

But I'm sure there are better/more efficient set ups than I had.

Staying Human seems like it could have a better bonus than being Elf, dependant on if you need to wear elf armor (I did).
