How much item level we need for the new content?

[NanaWiloh]

You don't need to have that high an item level. I did it on drk at ilvl 382 with a 365 weapon. Just save your cooldowns for the swords. if you're still struggling you can get a few more genesis pieces they have raised the weekly cap to 900.

This is the best advice outside of better gear. No doubt save your Cd's for the swords
