Mage/Dark Wizard Need some help fixing this Fatal build

I want to do more challenges in each lootrun, but my build isn't good enough for damage or survivability once too many curses are active. Could I have some suggestions on what I can fix?

I plan on switching to a Warp build once I get Conduit of Spirit

Here's the build

Preferably nothing Untradeable, I get too many random lag spikes to beat any boss altar/Legendary Island
