Echo skull

Echo skull was a spell used by druids.

Effects
When cast, this spell allowed the caster to hear, see, and speak through a specific animal's skull. The skull had to be dried and it was also used as the focus when casting the spell. The spell was effective over any distance on the same plane. Additionally, the caster could cast certain spells, those that were ranged and had no material component or focus, through the skull. The spell expired if the skull was destroyed.

Components
In addition to verbal and somatic components, the spell required a focus: a dried skull of an animal.
