aegisskjoldur

The Ægisskjöldur is the Shield of Terror. Drawn on black paper or parchment in crow’s bile, it should be placed in a nest where a crow is brooding its eggs, and left there until the chicks have hatched and flown the nest. Only then will the symbol have reached the power required to defend its holder from a multitude of enemies. After its activation, for the duration of the spell, a fluctuating rune will protect you. The first time that a creature strikes the caster with a melee attack, the illusion of a black dragon will be released from the rune, invoking the attacker’s most terrible fears. The creature, struck by the illusion, must make a Wisdom saving throw or take 12d6 psychic damage and be frightened and incapacitated for one minute. On a successful save, the creature takes only half the damage and is not frightened and incapacitated.
