Assassin/Ninja Thrunda Ripsaw Build

I wanted to do a spell damage build with mana steal with my Thrunda Ripsaw, so I created this build:

I'd like to know what you guys think about it, and if you have any ideas on how to improve it, please let me know.

I'd like to put priority on spell damage, mana steal and not having a negative health regen, but if theres a way to improve that and life steal as well, this would be very nice.

Also, I don't have enough money for buying a mythic.

I'm also listening to suggestions for builds of any sort that includes "The Exploited" (Lv. 100 Air Dagger from Eldritch Outlook dungeon)

Bigger Spin, Super slow manasteal with chain lightning for even more mana steal.
