Stamina implant

The stamina implant is an item from Strife that can be offered to Gerard, who will increase the player's stamina stat by 10 points. In the early stages of the game, stamina implants are received from Macil in exchange for completing his assignments; later on, as the player travels further afield they will receive stamina upgrades directly when important objectives are completed.

This item is more beneficial than the accuracy upgrade because stamina increases both the player's maximum health and the strength and damage of the punch dagger.
