How thorns (dual blader) works

Looks like the damage boost on final cut differs for each skill. So there needs to be experiments done. And the skill kills you if you're not careful when you charge and activate, 65% of max hp ouch.

Here's another uber damage with final cut, Aran or Dual blader? =/
And it looks like sharp eyes and thorns don't stack, in fact, they replace each others' buff so looks like DB won't be liking archers.
