Summoners are specialized MU Online spellcasters built around curses and control instead of traditional pet summoning. Sleep provides hard lockdown in PvP, Innovation lowers enemy defenses, and Chain Lightning offers efficient AoE damage and control while leveling. In organized events and Castle Siege, Summoners shine as tactical disruptors, softening targets and breaking enemy formations with stacked debuffs. According to the current bonus‑damage chart, Summoners gain extra damage against Rage Fighter and Grow Lancer but are vulnerable to Magic Gladiator and Dark Lord.
