Multistrike Tec Slam Jugg

Okay, so returning player here, trying to make a uniqueish build I can call my own. Last I played was 2.6 or something so I want to try something new, and asking you to tell me if it's a stupid sink of currency.

Tectonic Slam looks fun. I want to use multistrike with it. To sustain that I came up with the following:

-I'll go Jugg (that's pretty much self explenatory).
-I'll go Staves (more endurance charge generation on the wheel)
-I'll use The Red Nightmare (gonna get to a decent block chance with it to help mitigate damage from Abyssus)
-I'll use Undeniable + Oskarm and scale a bunch of accuracy
-Gonna use Eye of Innocence + Mokou's embrace
-Thanks to the crazy crit chance of Oskarm I'll ignite a lot
-Eye of Innocence triggers Unflinching
-Eye of Innocence also triggers Vengeance, so if I get a +1 curse modded one I can use Vengenace + Inc AoE + Curse on hit for an easy automated curse setup (alternatively with windshriek/windscream AND +1 curse EoI it can apply both Flamability and Ele Weakness in boss fights)
-Mana sustain w/ Blood Magic

Here is my planned lvl 90 tree:

Is it even worth the trouble? Is it even better than a Tidebreaker/Tec Slam build? Maybe Kingsguard over Kaom's?
