Equipment Fusion is a crucial mechanic for optimizing your party. By combining two identical pieces of equipment, you can transfer a skill from one to the other, or enhance an existing skill's potency. This allows you to create custom gear with the exact skill combinations you desire. The 'Skill Stacking' system then takes these individual skills and, when arranged in specific patterns on your equipment grid, unlocks powerful 'Stacking Bonuses' (e.g., 5 of the same skill in a row) and 'Line Bonuses' (e.g., specific skills in a column). Mastering this system is key to unlocking your party's full potential and overcoming the toughest challenges. Experiment with different combinations and consult the in-game skill menu for potential bonuses.
