Rycudas are first encountered hovering in place; when approached, they become mobile. Their main means of attack consist in stopping for a moment in midair, followed by unleashing a bolt of lightning from their beaks that deals considerable damage.
Because they are usually found high in the air, it may be difficult to hit them. A slashing weapon that traces a vertical arc, like a great sword or an axe, or a spell that covers a big area, like Last Scream, are recommended to fight them.
Their soul, Chain Lightning, is useful if one is looking to get their hands on the Mothman's soul. With it, the player can make their way to The Pinnacle and shoot a bolt of lightning at the searchlight's generator found there to summon the Mothman and kill it.
