Hmm, it does specify weapon skills, doesn't it... Oh well, Trick Attack and a Triple Attack on Aeolian Edge should have a similar effect.

Doubt it would extend duration, it'll just hit three times. Probably want to save it for Aeolian Edge, or the other new skill that still seems to have gone unexplained if that's of equal potency. Wonder how it would fare for Death Blossom actually... Dragoons force crit never seemed to force a crit on every hit of an AoE, would be disappointing if this is the same.
