Moon Slayer — In-Depth Analysis
Moon Slayer is the signature melee mythical for players who have mastered the "Six Eyed Demon" title — a clear nod to Gojo's Six Eyes in Jujutsu Kaisen, granting the wielder inhuman perception and lethal moon-elemental strikes. As a boss drop the weapon leans heavily into high-damage single-target burst: expect wide crescent slashes that cover surprising range for a melee build, paired with a short invulnerability window during the signature finisher that experienced players use to absorb punishes. It shines hardest in duels and 1v1 ranked play where its damage ceiling dwarfs nearly everything at this rarity tier.
The Six Eyed Demon title requirement shapes the entire build around precision over sustainability. Pair Moon Slayer with a stat line that favors Power above all else, and look for Fruits or accessories that add projectile tracking to cover the rare gap when opponents create distance. The weapon's cooldown structure is long per move but devastating on connection — a single full combo in a duel is often a game-ender, so the meta around it is learning to land that one-shot window rather than winning a sustained fight.
Because Moon Slayer only drops from a specific boss and also requires a premium title gate, its supply is the tightest of any standard-boss mythical. Expect to pay 37 500 Gems or 1 399 Robux at the shop, making it one of the most expensive shop purchases available. In player trading it commands four or more high-tier mythicals; sellers know the double barrier (boss drop plus title) keeps demand perpetually ahead of supply, and price accordingly.
