Scholar of the First SinEdit
In Scholar of the First Sin, Felicia the Brave can be summoned as a shade in The Lost Bastille. Her summoning sign can be found near the switch that opens the gate to the hallway leading to the Ruin Sentinels.
Felicia will be very useful against the Archdrakes waiting outside the hut but be mindful that the Witchtree's and the Archdrakes themselves will eventually overrun her if she is not assisted. It is wise to kill the Witchtree's to ease the archdrake attacks from killing her quickly. She will attack any enemy on sight including Dark Spirits or Arbiter Spirits and do excellent damage against them. If her health reaches half, she will use her Estus Flask to heal herself, albeit very slightly.
