Yamato

Transmutation Casting Time: 1 Action Range: Self Components: V, S Duration: Concentration, up to 1 minute Description: You envelop yourself in swirling shadows that obscure your form and dampen incoming attacks. For the duration, you gain resistance to necrotic damage and any non-magical weapon damage (piercing, slashing and bludgeoning). Additionally, attackers have disadvantage on attack rolls against you. Each time an attacker misses due to this effect, they take 1d8 necrotic damage as the shadows retaliate. The damage increases by 1d8 when you reach 11th level (2d8) and 17th level (3d8).
