Mage/Dark Wizard Mage Lootrun Build need help

I want better builds if theres other options. But no LI accessories pls.
These are what I have.

[Mythic]
- Fatal
- Warp
- Slayer
- Crusade Sabatons

 

This is the build I'm currently using. It's incredibly not-meta and probably objectively bad, but it can do decently well on lootruns (though I think the farthest I've gone with it was only ~60-70 challenges so YMMV). It does use a gold hydro necklace for mana and spell damage, but you could swap it out for something else; the skill points it gives aren't necessary and the mana isn't really. Someone better at building could certainly optimize it quite a bit, but it works well enough for me.
