Wondrous Item, artifact
At the smell of blood you can go into a frenzied rage. After you cause another creature to lose HP or are injured by another creature and lose HP yourself, you can use your reaction to activate this ability. When you do, you gain +1 AC, increase your walking speed by 5ft, and add +1 to your attack rolls for up to 1 minute. This ability cannot be used again until after a short rest.
Notes: Bonus: Armor Class, Bonus: Speed, Bonus: Dexterity Attacks
