Naruto: Rise of the Hidden World

This spell allows the caster to break past their body's natural limits, unleashing a surge of chakra that enhances their physical prowess. For the duration, the caster gains advantage on all melee attack rolls, adds an additional 4d6 damage to unarmed attacks, and forces nearby enemies to make a Constitution saving throw or be knocked prone at the start of the caster's turn, all while suffering damage at the end of each turn due to the strain of the spell.
