Chimera's Might

You have developed traits similar to that of a chimera, granting you the following benefits:

• Increase your Strength or Constitution by 1, to a maximum of 20.
• Once per turn, when you deal damage with an unarmed strike, you can increase the damage you deal by an amount equal to your proficiency bonus.
• If you make an unarmed strike as part of the Attack action on your turn, you can take the Disengage action as a bonus action. When you do so, you gain a flying speed equal to your walking speed until the start of your next turn.
• When you take the Attack action, you can replace one of your attacks with an exhalation of fire in a 15-foot cone. Each creature in that area must make a Dexterity saving throw (DC 8 + your proficiency bonus + your Constitution modifier). A creature takes 1d8 fire damage on a failed save, or half as much on a successful one. This damage increase by 1d8 when you reach 5th level (2d8), 11th level (3d8), and 17th level (4d8). You can use this feature a number of times equal to your proficiency bonus, and you regain all expended uses when you finish a long rest.
