When you are invisible, this will not attack enemies (and thus will not trigger alarms) so having [Thumper] is more than justified

[Fired Up] is only good if you have heat on a companion weapon, I tend to use Cold + Corrosive as additional status effects for things like [Condition Overload] in addition to other elements in my builds, so that is omitted here

[Sacrifice] is amazing when paired with [Primed Regen], as your companion is going to get downed anyway while trying to revive you (ESPECIALLY on Steel Path) so having the immunity from that giving it time to revive is incredible. Not only that, [Sacrifice] ALSO gives you the ability to reposition and use your secondary while downed, even in Solo play when normally that would not be the case.
