Template:AddingHit
It is possible to add Hit % to enemy weapons (and only enemy weapons) despite the attribute not being eligible for increase through Paganini's Exchange in 
Gallon's Shop.
To add hit % to enemy weapons, a character must speak with Dr. Montague in the episode 4 quest Claire's Deal 5 after unlocking the feature through a sidequest present in the government quest 9-5:The Chosen (1/2).
Once the sidequest is completed, speaking to Dr. Montague in Claire's Deal 5 with an enemy weapon in the inventory will have him offer to further enhance the weapon through a process requiring 
Photon Crystals. This process involves giving Dr. Montague an increasing number of Photon Crystals (starting with one) for a decreasing percentage chance (starting at 100%) of adding 10% more Hit to the weapon in question each time, to a maximum of 50% Hit.
| Cost | Success Rate | Total Hit |
|---|---|---|
| 1 | 100% | 10 |
| 2 | 80% | 20 |
| 3 | 60% | 30 |
| 4 | 40% | 40 |
| 5 | 20% | 50 |
The minimum amount of Photon Crystals a player must spend, therefore, is as follows:
- 1 Photon Crystal for 10% Hit (1);
- +2 for 20% Hit (3);
- +3 for 30% Hit (6);
- +4 for 40% Hit (10);
- +5 for 50% Hit (15)
For a combined total of 15 Photon Crystals when all attempts are successes. The probability of succeeding on each increment in only one try is 3.84%. The average number of Photon Crystals required to reach 50 Hit is 42.5.
To unlock this option, the player must follow these steps:
- Start the quest 9-5:The Chosen (1/2);
- Proceed through the quest as normal until the large, circular crater room in Desert 1;
- In this room, all enemies must be defeated within five minutes of entering the room;
- If done successfully, a cutscene will play showing Dr. Montague appearing, who must be spoken to;
- Proceed to the end of the quest as normal, and speak to Dr. Montague a second time in the last room before heading back to Pioneer 2
