Very nice sheet.
One thing about Pierce tho: you need Shock debuff to apply +2 extra hits, and it gets +70% damage instead of +50% from Serpentineās debuff.
Iām personally making Highlander 2 -> Hop3 -> Dragoon 3 so I can cause Shock debuff with Crown at 100% chance and Bleed with Crosscut (with 3x Prison Cutter cards) for an extra +30% dmg.
About your explanation about Dragoon skills being multi-hit, Iāve always felt Serpentineās attrib had a quite high chance to cause bleeding (but certainly not 100%). If I were to guess, Iād say ~70% chance to bleed with the skill is a reasonable approximation (7 hits with 10% chance each). However this wouldnāt be possible if Serpentine consisted of only 3 true multi-hits (should be 3 * 10% = ~30% chance), unless the attribute also works for fake multi-hits.
It could be an entirely new type of fake multi-hit⦠But who knows.
