Draconic Fortitude. Your hit point maximum increases by an amount equal to twice your level when you gain this feat. Whenever you gain a level thereafter, your hit point maximum increases by an additional 2 hit points.

Ancient Technique

• When you hit a creature with an opportunity attack, the creature's speed becomes 0 for the rest of the turn.
• Creatures provoke opportunity attacks from you even if they take the Disengage action before leaving your reach.
• When a creature within 5 feet of you makes an attack against a target other than you (and that target doesn't have this feat), you can use your reaction to make a melee weapon attack against the attacking creature.

Chromatic Infusion. As a bonus action, you can touch a simple or martial weapon and infuse it with one of the following damage types: acid, cold, fire, lightning, or poison. For the next minute, the weapon deals an extra 1d8 damage of the chosen type when it hits. You can use this bonus action a number of times equal to your proficiency bonus. All expended uses are returned at the next dawn.
