Upheaval and Onslaught use

[Schrute]

upheaval is a 350 potency hit when at full health in deliverance, so you want to use this every time it comes off CD because it IS a dmg increase compared to a single fellcleave. As for onslaught, I use this very often because if you notice if you do not use this in between your zerk windows you will constantly waste BG in one of two ways: you will lose 20 BG because you just used onslaught once and you just did eye or butchers block and now you back at 100 BG and have time for one more combo just before zerk; OR your fellcleave and now you behind on BG for the upcoming zerk window.

In short I found it necessary to use onslaught 2-3 times between zerk windows because it is oGCD, making it easier to regain the perfect amount of BG just in time for your zerk windows. Fellcleave is a GCD and 50 BG, which will set you back even further in BG for your upcoming zerk window.

This. Onslaught's cd of 15 seconds allows you to generate 50 to 60 gauge within that time. Meaning, if zerk comes up in 20ish seconds, and you're already at 50 to 60 gauge, you better onslaught right now to ensure you can use it again to dump that last little bit of gauge before your zerk phase. There's no worse feeling than being capped on gauge, having nothing but FC to spend it on, and having your zerk coming up within a few globals.
