Ear Whistle

This spell is a part of the Tinnitus spell chain and can be found in the Tinnitus rune stone.

This spell emits a high pitch whistle that only enemies can hear. This whistle noise drives the target crazy, requiring them to make an impossible mental balance check. A failed check is followed by a roll of a 1d6 with even numbers meaning the target goes berserk for the duration of this spell and odd numbers meaning that the target will attack itself for the duration of the spell.
