Assassin/Ninja Level 80 assassin build

I'm looking for a level 80 spell spam build with high mana regen (at least 4/5) I don't mind if it's glassy, I'm mainly focused on the damage with spells.

 

Mana Steal is actually better for assassin because mana regen does not tick while vanished

Here’s a solid build for both combat and xp at lvl 80: https://wynnbuilder.github.io/#4_0690cB0cA0c80cF0cF0TN0c90pa0O0e1f0i0d1I00000
