I am guessing Amascut spent a lot of time in the shape of a lioness before she went nuts, so she's learned to lean on the senses that a predator does. Senses that let her keep tabs on her prey, such as binocular vision and binaural hearing. Smell is good for finding very generic directions but for pining down a location nothing beats vision and hearing.

She also probably has senses connected with being a Grim Reaper type-thing still available. A connection with death and time, maybe.

Evil Chicken probably has extra senses related to teleportation (sensing weaknesses in the fabric of reality or something like that) and most definitely has a really long range sense that is attuned to distraction and inattention. It also has a weird way of just knowing names.

Probably like all chickens and other birds Evil Chicken has a very good sense of space and position.
