 * Ethereal Stride: Ichabarr and up to three nearby willing creatures can magically enter the Ethereal Plane from the Material Plane, or vice versa.
 * Actions:
 * Multiattack: Ichabarr can make two attacks: either one with their pike and another with their hooves, or two with their longbow.
 * Pike: A melee weapon attack that deals piercing and necrotic damage.

 * Longbow: A ranged weapon attack that deals piercing and necrotic damage.
