Need help with a Chronomancer build in a new league.

Hey guys first time playing as chronomancer. Need help with this build, not a lot of chrono players this league.

I like how it wipes out the mobs with AOE, but i kinda need something to melt bosses.
I know my items are shit, i did not invest yet in a build, bought the cheapest stuff available.

Anyway I need some guidance, or insights from veteran builders what will be the most optimal passive skills to pick, special items for this build (rings, amulet, jewel, wand, and so on. what gems to drop and which one to alter.

I had a hard time memorizing all the items/gem/passive/rares combinations that were before the update but now i just feel lost.

Also really like the synergy of repulsion in blasphemy, given the increased area from chrono ascend, entire map is exploding from a single skill.

I got cast on crit meteor cuz i don't know another way to kill bosses efficiently, if somebody proposes something better, i am ok to drop it for something else if it will give me enough dmg and survivability to kill any boss later.

I am still lvl 73 just started progressing the endgame.

Thanks in advance.
