Season X introduced MU's first new character in five years — the Grow Lancer — alongside the Evomon summoning event, expanded elemental play and skill engraving. It marks the start of 'modern MU', where the elemental system becomes central to power.
A graceful lance-wielder who starts at a higher level with her own gear line and a master tree expanded in Part 2. Her mobile, critical-focused playstyle was unlike anything in the classic roster.
Summon! Evomon added an evolving monster event: hatch it, feed it, and fight the result for scaling rewards — a compact, repeatable event that servers love to tune.
Part 3 widened the pentagram system with the Errtel of Radiance and introduced skill engraving, letting players etch bonus effects onto skills — two systems that define late-game builds from here on.
Item drop logic and experience flow were rebalanced, with mastery-level items appearing in Part 2 as a bridge to the mastery-gear seasons ahead.
