As far as I can see there is only 1 unique weapon in the game tailered towards Matador (Moringponia Rapier) with fixed stats in the game unlike Fencer who have a multitude of such weapons. Here are some ideas I hope the development team picks up in some form.
Vaivora Rapier Du
Aoe attack ratio +1
All Matador skills +2
If you wear a shield, Faena will always apply the maximum number of hits.
Vaivora Rapier Trys
Crit rate 699
Aoe attack ratio +2
Paso Doble and Corrida Finale will deal 1 additional hit on shocked enemies and 1 additional hit on bleeding enemies. If enemies are shocked and bleeding, they will receive double the number of original hits from Paso Doble (4>8) and Corrida Finale (3>6).
Vaivora Rapier Keturi
Block Penetration 500
While Guardian is active, all Matador attack skills will deal 50% more dmg
Negates the damage reduction effect of High Guard
Vaivora Rapier Penki
All Matador skill levels +3
If a barbarian skill is used during backslides 5 second 100% increase evasion buff, it will bypass 50% of the enemies def.
