My Bloodcurse-infused Axe & Dagger got its unique special ability moveset swapped.
with the Axatana Hexapod Core ability, I just found the weapon and tried the moveset, including the ability, and when i switched back to my maxed-out axe and dagger its unique "Magdalena's memento" is doing another completely different moveset now lol, i think it is the same as the Axatana. It is supposed to be a whirlwind, not a series of strikes advancing forward.
