How do I get Mothman, Yeti, and Flying Humanoid souls?
for easier reference refer to the map link at the top of the page (Answer taken from Dragon_Blast’s topic.) Mothman: In the hallway with two Final guards in the top floor. Use the Rycuda (blue thunder bird) soul on the battery by the spotlight to activate it. Mothman will fly in. Yeti: Go to the very first room of the castle (where you first came in) and use the skeleton waiter soul near the yeti in the background. Unleash attacks (Yeti is vulnerable to fire) to finish him before he jumps back. Flying Humanoid: In the room before Zephyr, use the Mandragora soul.
