Kurna Leaves

Like coca leaves, basically, but they improve one aspect that the user is using. So, if they're casting magic, it makes them more magically gifted. If they're running, they gain endurance. If they're lifting, they gain strength. Function: Grants the user great strength. The user tucks it into their mouth under their tongue. Used by a specific tribe of humans pre-Tek. Perhaps also used by Vol’Kar. Later used by more people, but not a common plant.
