Through foul lineage or some magical artifice, you have attained an inkling of the natural strength possessed by a yeti. You gain a +1 to Strength or Constitution. In addition, as a bonus action, you can call on the power of this elemental magic to imbue your attacks with additional power. The next time you hit a target with a melee or thrown weapon attack within the next minute, the attack deals an extra 1d6 damage of the weapon's type, and If the target is a creature, it must succeed on a Strength saving throw or be knocked prone.
