PoE Xelmed builds

I made my cold dot occultist It is a pretty solid build. Which can easily farm most of the content. But I cannot complete ubers except uber shaper. I have 89 all resistance(thanks to +2 cold max resistance from a relic) 90% physical resistance. Damage is perfect for mapping. Even ok for 100% delirium. But it feels a bit slow on ubers. Now, I am trying to find a way to improve my DPS without sacrificing survivability. And sadly, I am out of ideas now. If someone has any suggestions for 50 divines budget I will be reall
