Adrenaline

After using the Adrenaline, you become invulnerable to all damage types for the next 2 rounds of combat. At the start of your turn on the round that the Adrenaline wears off, you take twice the amount of total damage that you would've otherwise taken, all at once.

The liquid in this potion appears completely clear, but acts as a strong stimulant to the body for several seconds after taking it. People who use it find that they become extremely aware of each individual sound and smell around them among their other senses. After being tested on small animals before they were decapitated, they appeared to have full control over their body seconds after the connection to their brain was severed.
