"Ultimate Overlord's Mega Magic Sword"

A 4-star claymore with Energy Recharge and two ATK bonuses, one of which can increase with Merusea Village progress.

Released Dec 21, 2023

The Ultimate Overlord's Mega Magic Sword combines Energy Recharge with ATK increases. Consider it for a claymore user whose build benefits from both, especially if you have helped Melusines in Merusea Village. The weapon’s effect gives an additional ATK bonus of up to its stated amount based on that progress; the required number of Melusines for the full bonus is not specified.

Understand "Ultimate Overlord's Mega Magic Sword"

Useful when…

  • A claymore user who benefits from ATK and Energy Recharge to help meet Elemental Burst energy needs.
  • A player who has helped Melusines in Merusea Village and wants the additional progress-based ATK bonus.

Stats and effect

This 4-star claymore has base ATK 43.7349 and Energy Recharge as its secondary stat. Its passive has no listed combat trigger: at refinement 1, it grants 12% ATK and up to an additional 12% ATK based on the number of Melusines helped in Merusea Village. At refinement 5, those figures are 24% and up to an additional 24%. The exact progress required for the maximum bonus is not specified.

When to consider it

The Energy Recharge secondary stat can help a wielder meet Elemental Burst energy needs, while its ATK bonuses suit damage that benefits from ATK. Its usefulness therefore depends on the character’s needs and how much Merusea Village progress you have made. The listed facts give no Energy Recharge value or character-specific compatibility, so assess those alongside the weapon’s stated bonuses.

Ascension and refinement

Weapon ascension and refinement are separate tracks. Ascension advances through six stages; the listed example costs cover transitions 0→1, 3→4, and 5→6, including Mora and named materials. Refinement raises the listed ATK bonuses from 12% each at rank 1 to 24% each at rank 5. Example refinement costs specify one Super-Duper Invincible Shining Sparkly Magic Crystal and Mora for transitions 1→2, 3→4, and 4→5; those examples do not establish the cost of every transition. Consider refinement in light of the stronger stated bonuses and the listed costs for those ranks.

How its mechanics differ from other claymores

Akuoumaru has an ATK secondary stat and increases the wielder’s Elemental Burst DMG based on the party’s combined maximum Energy capacity, up to its stated cap. A Thousand Blazing Suns grants ATK and CRIT DMG after the wielder uses an Elemental Skill or Burst; its effect can be extended by Normal or Charged Attacks that deal Elemental DMG, and it has an additional condition involving Nightsoul’s Blessing. A Teaspoon of Transcendence grants ATK and increases Stellar-Conduct and Stellar Swirl reaction DMG when Charged Attacks hit. These are distinct conditions and effects; the comparison does not establish that any of them is a direct substitute or universally preferable.

Limitations and tradeoffs

  • The additional ATK bonus depends on Merusea Village progress, and the threshold for the full amount is unspecified.
  • Only example costs are provided for some ascension and refinement transitions.

Common mistakes to avoid

  • Treating the additional ATK bonus as a fixed full amount regardless of Merusea Village progress.
  • Assuming the example refinement costs establish the cost for every rank transition.
  • Ignoring whether the wielder benefits from both ATK and Energy Recharge.
