Double Slash

Fairy Dust
Priscilla pauses, then exhales a large cloud of blue particles in front of her.

Invisibility
Priscilla turns invisible, whilst still being able to attack the player. Leaves large footprints in the snow.

Drops
Upon defeating, players will obtain the Soul of Priscilla. Additionally, by cutting off her tail players can also obtain Priscilla's Dagger. An achievement/trophy is awarded upon her defeat.

Strategies
She will become invisible as soon as she is attacked. Once she is invisible the only way to determine where she is will be is to watch for the large footprints that she leaves behind her in the snow. She will turn visible again when her poise is broken. For the fight with it is wise to move into position prior to starting since as she is initially neutral. It is recommended to go for her tail first, as there will be an opportunity to get a few free hits in before she attacks. When she begins to be hostile players should get in close and deal as much damage as possible, wielding weapons two handed can help with that. With enough concentrated strikes the tail should come off awarding the player with Priscilla's Dagger.
