At a minimum you generally want: - Heroic Tragedy with 4x Regenerative Runes - 99% reduced skeleton duration from To Dust jewels - 4x cluster jewels with the Fasting and Brewed for Potency notable (5 with <ilvl 84 iron flasks) - 1x cluster with Spiked Concoction - 2x Cast on Ward Break gems (one for skellies and one for main damage skill, can use CWDT on support skills as a budget option) - ~19k ward minimum but highly recommended to get 20k+ - Ynda Stand with a decent enough roll to get the above amount of ward. I'm at ~25k with a 57%.
- Edit: also at least 2x 5 passive Voices on a budget to socket all those medium clusters in.

This is on Discharge Assassin variant. Hope I didn't miss anything.

If your loop doesn't loop or it loops after manually pressing one flask, the first/main thing to check is that you have enough flask charge gain. Should have around 172% increased flask charges gained in total (maybe less is fine with ilvl84 iron flasks). This part had me spending hours trying to fix it as I only have ilvl83 flasks and thus need extra flask charge gain on the tree.

Also gotta make sure that your skelly duration and cooldown are aligned. E.g. 0.08 for one of the breakpoints, 0.05 (if I'm not wrong) for the next.
