Help with Trinity of Elements Build

Hello dear forum,

I’ve been working on a build based on Trinity of Elements and mobility for a long time.
Unfortunately, at level 72, I don’t know how to further optimize it.
Unfortunately, I didn’t find a build in the databases that is based on this spell. It doesn’t have to be an S-tier build but I’m surprised there isn’t one yet as the spell itself is beautiful. My current problem is that my Elemental Nova does just as much damage as my Trinity of Elements, which is kind of counterproductive. I would be happy if you could take a look at the build and maybe have ideas for me to improve it. Also which items or other skills could possibly help.

Or is the best to copy the Hydrahedron Runemaster and play it instead with trinity of elements?

PS1: Does the “copied scrolls” skill work with Trinity of Elements? Never seen two at the same time or are they on top of each other and I don’t see them?
PS2: I hope my English is understandable
