Vrondiss's Ancestral Enragement

You channel draconic ancestral magic through yourself, forcing each hostile creature within 25 ft of you to succeed on a Wisdom saving throw  (which they have disadvantage on if you are a dragonborn or half-dragon) or have disadvantage on attack rolls against summoned creatures for the next 20 minutes. After this, you summon 1d6+1 spiritual, Large sized berserkers with 72 hit points each that have resistance to bludgeoning, piercing, and slashing damage from nonmagical attacks that resemble giant dragonborn at a point you can see within range. They also have resistance to the type of damage you were dealt right before summoning them, and to one other damage type of your choice from fire, acid, cold, poison, force, psychic, necrotic, radiant, lightning, or thunder. They remain for the duration, as long as you maintain concentration.

At Higher Levels. If you cast this spell using a spell slot of 6th level or higher, you can summon 1d6 additional spectral berserkers for every spell slot above 5th.
