Unmatched Versatility: Ultimate Overlord’s Mega Magic Sword at a Glance

This weapon brings more than just its whimsical name to your arsenal. As a 4-star Claymore, the Ultimate Overlord’s Mega Magic Sword supplies an impressive boost to Energy Recharge while granting significant Attack percentage increases through a quest-based progression mechanic. Its playful design echoes the cheerful spirit of the Melusines and is said to be wielded by the one “who rules the seas”—further enhancing its lore-rich appeal.

Weapon Stats and Scaling

  • Weapon Type: Claymore
  • Rarity: 4-star
  • Base ATK (Lv. 1 – Lv. 90): 44 – 565
  • Secondary Stat: Energy Recharge (6.7% – 30.6%)

With one of the highest base Energy Recharge stats among 4-star claymores, this weapon is invaluable for characters needing frequent Elemental Bursts, while maintaining robust Attack scaling as you level up.

Weapon Passive: Melussistance! – Power That Grows With You

The claymore’s passive ability, Melussistance! (sometimes listed as “We Believe in You”), provides:

  • Refinement 1: Increases ATK by 12%. Grants an additional ATK bonus up to 12% based on the number of Melusines you help in Merusea Village (Fontaine).
  • Refinement 5: Increases ATK by 24%. Grants an additional ATK bonus up to 24% from helping Melusines.

The total ATK bonus caps at a staggering 48% at maximum refinement, dwarfed only by the player’s questing efforts in Fontaine. This makes the sword uniquely rewarding for thorough world exploration, promising greater strength as you engage with the world’s lore and side quests.

How to Obtain the Ultimate Overlord’s Mega Magic Sword

This claymore was exclusively available during the “Roses and Muskets” event in version 4.3. Players earned it and its refinement materials (Super-Duper Invincible Shining Sparkly Magic Crystal) through event activities and challenges. As with most event weapons, it cannot be obtained outside its original event period and is thus a collector’s gem for those who played during Fontaine’s debut arc.

Best Characters and Team Synergy

The Ultimate Overlord’s Mega Magic Sword shines brightest in the hands of characters who benefit from both high ATK and Energy Recharge. Optimal candidates include:

  • Beidou: Her Elemental Burst scales with ATK and is reliant on efficient energy generation, making her an ideal user.
  • Eula: Needs substantial Energy Recharge and attack; this weapon helps achieve frequent burst uptime.
  • Diluc: Appreciates the boost to both stats for smoother rotations.
  • Razor: Enhanced burst frequency and more sustained DPS output.

Whether building a main DPS or a burst-oriented sub-DPS, this claymore fills the gap for characters who often struggle to balance energy and attack in their gear selection.
