Berserker Spangenhelm (Patreon)

Wondrous item, very rare (requires attunement)

A conical masked helm, topped with pointed horns bursting with power granted from the world tree. Imbued with bestial aggression, these horned warriors were feared throughout the lands. While wearing this helmet, you gain a +1 bonus to your AC and have advantage on saving throws against being frightened.

Inspire Frenzy. While wearing this helmet, as an action you unleash a battle cry to call those around you to barbaric combat. Each other creature within 30 feet of you must make a Wisdom saving throw. The DC is equal to 10 + your Strength modifier + your proficiency bonus. On a failed save, the target becomes berserk. While berserk, the target ignores the effects of being frightened and at the start of its turns moves directly to the nearest creature and uses the attack action against that creature. Any attack made this way is made with advantage. If the target is concentrating on a spell, they automatically fail their saving throw. A creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success. Once you use this property it can't be used again until you finish a short or long rest.

Goring Rush. If you move at least 20 feet in a straight line towards a creature, you can make an unarmed strike with this helmet against the target as a bonus action. On a hit, this attack deals an amount of piercing damage equal to 1d6 + your Strength bonus. If the target is berserk, it takes an additional 1d6 piercing damage and makes its next saving throw against the berserk condition with disadvantage.

Some think of us as barbaric, savage, uncultured. Yet deep within every being lies a roaring animal, screaming for release. Those who follow the All-Seeing understand this to be true and in turn bestow the blessing of glorious battle to those who face our steel. We shall fill them with metal and expose their basest desires, turning the world into a symphony of wanton violence.
