does Face breaker + Hollow palm stack?

so since face breaker gives you flat phys and 1% per 5 main stat

hollow palm gives you damage based on your skill gem level

so these should work together yes? i cant see how these would conflict when the damage is being drawn from different area's unless im missing something

No, the damage from Hollow Palm is used for quarterstaff skills, the damage from Facebreakers is used for mace skills.

"

1% more Unarmed Damage per 5 Strength
+3 to Melee Strike Range while Unarmed
+1 to Armour per Strength

These Facebreaker mods work on quarterstaff skills as well.
