When you roll initiative, you may opt to use your Adrenaline Rush feature. If you use this feature, you gain temporary hit points and a bonus to your initiative roll equal to your level and +1 bonus to your AC. Additionally, the surprised condition does not prevent you from moving and taking actions normally.

When you use this feature, you have advantage on all athletics and acrobatics checks as well as strength, dexterity, and constitution saving throws.

The effects last for one minute and you can use this feature a number of times equal to your Constitution modifier and regain all expended uses at the end of a long rest.
