Kelpie the drowing horse (Patreon)

"My third from the chest is this little beauty. Please don't mind the smell too much." most of your party immediately hold their noses as this living smell of death and decaying bodies escapes.

A creature that looks half horse, half pile of seaweed, swims slowly through the air. "Now normally this beauty is only found in water but bound to this crystal it can swim in the air... and still bind and drown targets as if they were also in water. A little morbid but hey it's an undead horse what do you expect"
