Copyright Strike

You move like a good fart. For the duration, your movement doesn’t provoke opportunity attacks as you smell like shit.

Your fart is imbued with magical energy, enough to rival the spell plague. It is enough to make people wince. Once before the spell ends, you can give yourself advantage on one weapon attack roll on your turn. That attack deals an extra 1d8 force damage on a hit. Whether you hit or miss, your walking speed increases by 30 feet until the end of that turn.
