1: attack with your main hand weapon in attack action
triggers off hand with Nick mastery
triggers off hand Bonus action attack via Feat
2. 2nd attack with attack action(if 5th level ranger or higher.
now you have 3 options.
1. sacrifice 2nd main hand attack(if 5th level)
2. sacrifice off hand attack via Nick as a attack that is part of Attack action
3. sacrifice Bonus action and not use the Feat.
more or less, Dual wielder feat is a waste on beast master, as you need Bonus action for HM and for Beast command.
