Backstabber

Prerequisite: Rogue

You’re always on alert seeking an opening to backstab an enemy, striking at them when and where they least expect it. You gain the following benefits:

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

• When an enemy that is within your reach receives a critical hit from an ally, you can use your reaction to move up to half your speed and make an opportunity attack against that target with advantage.
