You understand how to utilize small and light weapons to great effectivity. You gain the following benefits:

• When an ally creature is adjacent to the target enemy you are attacking and is on opposite sides or corners of you, if you are using a light melee weapon for the attack, you can roll an additional damage die.
• When you hit a creature with an opportunity attack using a light melee weapon, you can move up to half your speed immediately after the attack and as part of the same reaction. This movement doesn't provoke opportunity attacks.
