Hi.
Since Discharge uses charges to deal flat damage, there is no big difference between triggering a spell every 500ms with 2 charges or every 250ms with 1 charge, this is why I choose CwC over CoC.

CwC triggers 2,86 times per second, so I'd have use it's multipliers as breakdowns

|Attack speed|Attacks between each cast| |:-|:-| |2,86|1| |5,72|2| |8,58|3| |11,44|4| |14,3|5|

Using The Red Trail combined with The Golden Rule, I'd have 1 frenzy charge per attack.
Combining Voll's Devotion w/ Romira's Banquet, I'd have 1 endurance or power charge per attack.
In other words, I have 2 charges per attack between casts.
3 attacks between each cast is easily achievable, 5 is a bit harder. So 4 sounds like a nice goal to go for.

For The Red Trail to give me it's bonuses, I have to be bleeding. That's why this build uses Golden Rule, to reflect inflicted bleedings, while Slayer Ascendancy do not take bleeding damage while leeching.

With 25% chance to bleed, granted by the skill tree, there are 96% of inflicting bleeding after 12 attacks, which are done normally in basically one second. But, I mean, at three attacks there is already 57% to inflict bleeding, which is enough.

All that said, here goes the PoB: https://pastebin.com/3RhD8LA1
I hope you enjoy it and tips are always appreciated. Probably going to play it next league. :3
