Gunbreaker is unable to continue Demon Slice combo vs multiple targets if missing

[Typhoria]

Sounds like the skill ought to work similarly to Monk's Arm of the Destroyer. If it's a no-target skill, hitting one thing is enough to proc the combo, even if you miss other enemies, presumably.

Monk skills are stance based. Paladin and Dark Knight AoE combos aren't targeted either and won't continue if the first hit doesn't connect with an enemy.
