Lohen and Thoma?

I don't have Durin nor the angel lady because I came back playing only recently. I do plan to get Durin eventually, but I don't like the angel enough to pull for her, so the plan for now is to kinda wait the new patches to see if other units that fit better Lohen will come out.

That out of the way, I have a Thoma I would like to play with him, expecially until a better unit comes out. My plan so far is to stick as much ER as possible on him so he will always have his burst up as soon as Lohen ends his rotation. Question is: is there maybe an artifact set, expecially anything that came out after Inazuma, that works amazing if Thoma specifically is in a team with Lohen? By not knowing a lot of the newer artifacts maybe there's something fun that, despite not being super meta, still allows me to play two characters I like together.

PS: yes I know there might be better alternatives to him, but I either don't have them or don't have them properly built, and I don't wanna "waste" resources building characters I don't really like to play
