Rolling Rusher (5e Feat)
From D&D Wiki
Prerequisites: You must be a Quartz of the Gem race.
You have determined the most direct way to damage your opponents. During combat, you may duck into a ball and roll to strike an enemy. If there is at least 10 feet between you and this opponent that is both clear and unhindered, you may use this ability to close the distance and perform a single melee attack. You have +2 to this attack roll. On a hit, the opponent takes 2d6 bludgeoning damage, and you make opposed Strength checks. If you beat the opponent, they are pushed back 5 feet. Use of this special attack takes your entire turn. Once you use this trait, you cannot use it again until you finish a long rest.
