Nuka Chemist

Nuka Chemist is a perk in Fallout: New Vegas.

Effects
You have unraveled some of the greatest mysteries of pre-War masters: formula for developing special Nuka-Colas! This perk unlocks special Nuka-Cola recipes at the workbench.
 * Nuka-Cola Victory (requires 3 Nuka-Cola, produces 1 Nuka-Cola Victory)
 * Nuka-Cola Quartz (requires 3 Nuka-Cola, produces 1 Nuka-Cola Quartz)
 * Ice cold Nuka-Cola (requires 3 Nuka-Cola, produces 2 ice cold Nuka-Cola)

Notably, these are all items that are finite or even rare in the normal game (even ice cold Nuka-Cola, which was easily replenishable in Fallout 3).
