Nimble Thri kreen

You have become more agile and evasive. You gain the following benefits:

• Increase your Dexterity score by 1, to a maximum of 20.
• If you move up to your full movement, without taking the dash action your AC is increased by 1 until the beginning of your next turn.
• When you make a melee attack against a creature, you don't provoke opportunity attacks from that creature for the rest of the turn, whether you hit or not.
• You gain an additional reaction each round, that can be used for any ability.
