Joseph

During the Celyste–Ametona War, Joseph becomes one of the architects of Celyste's campaign against Devante. Rather than relying on overwhelming force, he carefully manipulates the conflict to his advantage, leveraging Ametona's position to weaken Devante while minimizing unnecessary losses. Despite his brilliance as a strategist, Joseph quietly doubts his own abilities as a warrior, often placing greater trust in meticulous planning than in his personal strength. That uncertainty begins to disappear during the attempted assassination at Municro, where he and Myles stand against overwhelming odds. Surviving the battle gives Joseph a newfound confidence in himself, fundamentally changing both his outlook and the way he approaches leadership. 

Although born a prince, Joseph has little interest in standing apart from those he fights beside. Upon reuniting with Boone, he immediately asks him to abandon the formalities of royalty, wishing instead to be treated as an honorary member of the White Lions. As the journey continues, Joseph gradually forms genuine friendships with his companions. Boone earns his admiration through his unwavering commitment to doing what is right, Myles becomes the first person Joseph truly considers a friend after their stand at Municro, and Wise develops into a trusted confidant as the two bond over the pressure of living in the shadow of accomplished older brothers. Even when the White Lions return to Ametona, Joseph's lingering distrust never fully disappears, yet he ultimately places the greater mission above his personal feelings and honors the alliance forged between the two nations. 

The hardships Joseph endures transform him from a cautious strategist into one of the White Lions' most decisive leaders. While he never abandons the careful planning that made him successful during the war, he increasingly believes that hesitation allows dangerous enemies to gain the upper hand. Convinced that swift, calculated action is often the surest path to victory, Joseph becomes one of the party's strongest advocates for taking the initiative against the Proclaimers. Though his methods occasionally clash with Boone's more compassionate approach, both men ultimately share the same goal.

Unit Data

Unit Analysis

Joseph is widely regarded as one of the strongest units in The Lonely Mirror, and for good reason. He boasts excellent growths in Speed and Luck, allowing him to double many enemies while maintaining impressive avoid throughout the game. His Power, Resistance, and even Defense are all respectable for a mage, making him more durable than many of his magical peers despite his lower HP. Even though his Dexterity growth is somewhat shaky, Wind tomes possess high accuracy, which allows Joseph to remain a remarkably consistent offensive threat against most enemies. 

Joseph's greatest advantage is his combination of availability and exclusivity. As the game's only natural Wind mage, he faces virtually no competition for Wind tomes, allowing him to fully capitalize on an entire weapon type. Wind magic grants him a valuable niche by dealing effective damage to Pegasus Knights and Thunder magic users, which allows him to eliminate many dangerous enemies. His great availability also means that investing experience into Joseph rarely feels wasted, as he is required for several chapters and remains a reliable deployment choice whenever he is available. 

Joseph also possesses two outstanding promotion options that cater to different playstyles. Flight dramatically expands his offensive reach, allowing him to ignore terrain, reach priority targets with ease, and fully capitalize on his excellent Speed and Wind magic; when combined with Forseti's 2-3 range, he can safely pressure bosses and priority targets from distances that few other units can match. Wind Sage remains an excellent alternative for players who prefer a more defensive or support-oriented approach with staff utility. 

Despite his many strengths, Joseph is not without weaknesses. His greatest drawback is his permanent weakness to Fire magic, which makes enemy Fire tomes, particularly Meteor, a constant threat that requires careful positioning. His below-average Dexterity also makes Dark magic a poor long-term investment due to its lower hit rates, leaving Wind as his preferred weapon type throughout the game. While Joseph remains one of the strongest magic users from beginning to end, Excalibur does not receive bonus damage against monsters. This causes his offensive edge to diminish slightly during the monster-heavy endgame compared to some other legendary weapon users; however, his excellent mobility, Speed, and utility ensure he remains an outstanding unit. 

Overall, Joseph is one of the strongest magic users in The Lonely Mirror. His outstanding availability, exceptional Speed, exclusive access to Wind magic, and excellent promotion options allow him to remain a valuable contributor as soon as he joins. Regardless of his promotion, Joseph combines strong offense, excellent mobility or utility, and consistent performance in a way that few units can match. It is no surprise that many players consider him among the very best units in the game.
