Nimble Movement

You've become quicker and more nimble in your movements. You gain the following benefits:

• You increase your Dexterity or Intelligence score by 1, to a maximum of 20.
• Your speed increases by 10 feet.
• When you make a melee or unarmed attack against a creature, they suffer a -10 penalty to their attack roll for opportunity attacks towards you for the rest of the turn, whether you successfully hit or not.
