Street-Runner (Asteria)

You are fast, hard to pin down, and used to moving through crowded streets, alleys, ruins, and battlefields without losing momentum.

Increase your Dexterity score by 1, to a maximum of 20.

Your walking speed increases by 10 feet.

You ignore nonmagical difficult terrain.

Once per round, when a creature misses you with a melee attack, you may move up to 10 feet without provoking opportunity attacks.

If you move at least 20 feet before making an attack on your turn, opportunity attacks against you have disadvantage until the end of that turn.
