Charles had abandoned many of his early weapons and equipment.
For example, the second-hand Magnum Hand Shuttle that had followed him from the start, the Vampiric Hand Axe, and the magic alchemy staff he had later crafted for a considerable sum of money.
There were also some fine pieces of equipment that Charles had never really used, such as the assassin's Dagger, the two fingerless glove-shaped magic gun pouches, as well as the Crystal Vase and Bag of Insects obtained in Cappadocia City, and the Transcendent Knight's Spear he acquired from killing Zolman.
Originally, the assassin's Dagger had Antispace attributes and was a good infiltration weapon, but Charles had long since mastered the Colorless Blade, an inherent special ability that was more convenient than using equipment.
The magic gun pouches were spatial equipment, which had a significant disadvantage—their inability to be concealed. Once searched, they could never be hidden again, so they couldn't be carried around.
