Lower on the priority list than the rest, but still good to keep an eye on, are the TMP Stock and the Red9 Stock. With the Broken Butterfly, it increases the damage by x1.5, which is nothing to scoff at, but if the damage upgrades are purchased as well, the damage stands at a whopping 40.5. With the SG-09R, it increases the critical hit rate by 5, making it so most Ganados are put down with one clean shot. Though it may seem counter-intuitive to buy an Exclusive Upgrade ticket to get the exclusive upgrade on non-fully upgraded weapons, some weapons like the SG-09R and the Broken Butterfly's exclusive upgrades are so powerful that they make up for the lack of other upgrades. Weapon upgrades are extremely expensive, ranging from 80K to 100K Pesetas, so an Exclusive Upgrade Ticket can save a lot of Pesetas. Each weapon has its own exclusive upgrade and can only be used when all other upgrades for that weapon are complete unless an Exclusive Upgrade Ticket is purchased. A late-game item and the most expensive one on this list by far at 30 Spinels for the first and 40 for the second, exclusive upgrades for weapons are unlocked during Chapter 9 and are the final stage of upgrades.
