Please take a look at skill named “Hit Once” in Miqobot rotation designer. It is created exactly for this purpose.
Also, please note that Brunt Force and Deep Vigor can only be activated after chain #4, which means after 5 successful hits.
In order for this to happen, you need a node with at least 6 gathering attempts. In addition, clearing out-of-reach is not counted towards hit chain by the game, so you have to either use Toil or acquire Endless Toil trait.
The working rotation would look like this:
Toil
Hit Once
Hit Once
Hit Once
Hit Once
Hit Once
