Science! is a prerequisite for crafting some buildable objects for settlements and for making some mods, including most modifications to energy weapons.

 * Modify energy weapons with weapon mods, and you can also craft certain advanced armor mods. Each rank in this perk unlocks an additional rank of mods: rank 1 unlocks rank 1 mods, rank 2 unlocks rank 2 mods, etc.
 * Additionally, any ranks of Science! can be used to assist another player with crafting mods, i.e. player one has 2 ranks of Science! and player two has 1 rank, they can assist one another and effectively create rank 3 mods.
 * Each time this perk is taken, the level requirement increases by 4.
