Assassin/Ninja Help Improve build please

I'm looking for a tankier assassin build that is not full acrobat. I am currently using this https://wynnbuilder.github.io/build...11181-031g00001006CO0z0z0+0+0+0+0-1TldxalICw4 and was wondering if there is a better build I could be using or if there was a way to just improve this one. The build is intended for general use Any items are allowed except crafted armour.

 

I'm still trying to understand how you play these builds and don't know what the best tree is for this playstyle.

I came up with a hybrid build. Not sure if you wanted pure regen mana sustain and it has less jump height. Build has mixed mana but better life sustain: Inferno | Hybrid

Playstyle seems cool might have to try this myself.
