If the player brings Paganini the data from the terminal in Seabed during 
The West Tower quest, the "Enhance weapon's Photon" option will be available in Paganini's exchange in Gallon's Shop for the character that completes this sidequest (which can be completed on any difficulty).
- Note: Unlike The East Tower, there is no easy way to check through Hopkins if you have already completed The West Tower sidequest, as Hopkins in Gallon's Shop will say the same "My father is working on a huge project right now." line, both before completing the previous sidequest as well as after completing this one.
As a prerequisite to adding attributes to weapons, a character must first have collected The East Tower data for Paganini (refer to adding specials to ES weapons for directions).
- Start The West Tower after having completed The East Tower sidequest
- Talk to Hopkins in the lab (he is in the same place you would find him in Gallon's Shop for accessing Paganini)
- Traverse the Seabed Upper levels until you find and access the terminal containing the Research Data (you will receive a Quest Board item).
- Return to the lab and talk to Hopkins before ending the quest
Through the "Enhance weapon's Photon," the player may now increase attribute percentages on their weapons in exchange for set amounts of 
Photon Drops, at a rate of four Photon Drops per 1%, or 20 Photon Drops per 5% on an attribute. A Photon Sphere can also be used to add 30% to an attribute, but only if the attribute in question is 70% or less. The following restrictions apply to adding attributes:
- A weapon cannot have more than three attributes (The following weapons cannot have more than two (including Hit%):
Sealed J-Sword, Tsumikiri J-Sword, Lame d'Argent Excalibur) - ES Weapons cannot have attributes
- Hit cannot be added to a weapon
- Attributes cannot exceed 100%
