Potion

Information
Secret Recipes of the Ancients. Because there is no active technology involved in a potion, the user's technological capability does not affect their usefulness. They are however bolstered by the Genius perk.

Healing Save
A Healing Save can restore a small amount of healing in a pinch. Even though health is restored by moving about the map, this can be useful when the player is taking more damage than it is gaining.

Stun Potion
A stun potion can temporarily immobilize an enemy, in a similar fashion to a Shield Bash attack.
