Swing once hit two enemies… how about swing twice and hit once?
Focused Barrage 2 actions Feat 4
Barbarian Fighter Flourish
You continuously swing at an enemy until you hit its unprotected areas. Make two melee Strikes at your current multiple attack penalty and compare the best attack roll result to the ACs of the target. Roll damage only once and apply it to the creature if you hit. Focused Barrage counts as two attacks for your multiple attack penalty.
