Assassin/Ninja Help Looking for a new nulli/archangel build

With the release of the new Fruma expansion, my old build is a bit broken compared to what ot used to be, so my plan is to replace it, but i'm not sure what with.

My primary daggers are nulli and archangel, and i don't desire to switch from them, so the change would be replacing the armor and accessories.

Ideally, i am looking for a decently survivable (doesn't have to have high ehp) spellspam build with decent walkspeed, mana regen and lifesteal.

If anyone has a build they would suggest, i would love to know.
