You gain one of the following augmentations to your body. You may take this feat again at later levels and choose another augmentation to your body.

1. Exhaust Pipes: As a reaction when you take fire damage, you may expel steam from your body. Each creature in a 15 foot cone originating from your body in any direction must succeed on a DC 14 Dexterity saving throw or take 4d6 fire damage and become blinded until the start of your next turn. On a failed save, they take half the damage and are not blinded. You may do this a number of times equal to twice your proficiency modifier per long rest.
2. Jet Propulsors: As a bonus action, you may gain a flying speed equal to your walking speed for 1 minute. If this ends while you are in the air, you fall. You may do this twice per long rest.
3. Overclock: You may cast haste on yourself, requiring no concentration and lasting for 3 rounds. Once the spell ends, you are stunned, and at the end of each of your turns make a DC 18 Constitution saving throw. On a success, you are no longer stunned. If you do not succeed, the stunned condition lasts for a maximum of 1 minute or 10 rounds. You may cast haste in this way once per long rest.
4. Extra Battery: You gain proficiency in Constitution saving throws, and you gain an extra 1 max HP on a level up. Adjust your max HP for the level you are currently.
