It would probably be a level 4 skill like OC said, with the deathblow 4, fort def/res 3 icon.
Honestly I'm waiting for the day they introduce level 4 Duel skills which boost your bst to 175/180. Because I sure do love seeing Brave Veronica everywhere...
Well, it's all bound to happen. Though, if IS could help by boosting some units BST a bit (recent merge fix) I'm hoping they come up with something a bit better for older units (3-4 bst is still great, but it also affects newer units so ehh)
OC didn't say they'd be lvl 4 skills just that lvl 4 skills are a thing, and you would need that stance skill on the unit to get said breath skill so it wouldn't be a lvl 4 skill
