I don't think I realized before that there are three Matsuo skills enhanced by Evasion Power.
Demon Slayer: Evasion Power is also applied to your Etheric Defense.
Swordbreaker: Evasion Power is also applied to your Melee Defense.
Fire Dancer: Evasion Power is also applied to your Fire Defense.
Now a twitching bat wing gives +4 ED, MD, FD on top of evasion power, dancing blade +6, lonely travel sketch +4, etc. No special avatar for all three sword fighting or using another matsuo chip.
