Moon Lord

Solar Eruption. It passes through blocks, hits all three eyes, and lets you hide behind solid walls during Deathray. Safest weapon in the game for this fight. Stardust Dragon Staff (summoner) for hands-free DPS. Nebula Blaze (mage) for homing while mobile. Vortex Beater + Chlorophyte Bullets (ranger) for auto-tracking. If you can only pick one — Solar Eruption through walls is a different tier of safety.

Hand eyes first (25,000 HP, 40 DEF each), forehead eye last (45,000 HP, 50 DEF). Hand eyes fire Phantasmal Bolts and Eyes — dodgeable. The forehead eye fires Phantasmal Deathray — 150+ damage per tick. Killing the forehead eye last minimizes your time fighting alongside the Deathray. After all 3 eyes pop, the core (50,000 HP, 70 DEF) is exposed. Full DPS.

The Deathray sweeps horizontally from the forehead eye. Fly UP or DROP DOWN — cross the beam vertically at its narrowest point. Do NOT run sideways. The sweep tracks your horizontal position, so horizontal movement gets you killed. Rod of Discord teleports through it instantly — 6s cooldown and 1/6 HP penalty beats eating a Deathray. Multi-layer platforms give you vertical escape room.

Each kill drops 2 non-duplicate weapons from a 10-weapon pool (~20% each): Meowmere, Star Wrath, Terrarian, S.D.M.G., Last Prism, Lunar Flare, Rainbow Crystal Staff, Lunar Portal Staff, Celebration Mk2. Plus 70-90 Luminite (100% guaranteed) and a Portal Gun (100% guaranteed). Full collection takes roughly 8-12 kills.

No. Moon Bite only blocks lifesteal effects — Vampire Knives healing, Spectre Hood healing, etc. Potions and Nurse healing are completely unaffected by Moon Bite. You can drink potions and visit the Nurse during Moon Bite with no issues. This is one of the most common misconceptions about the fight.

Lunar Fragment armor for your class. Solar Flare (melee) — dash + shield for tankiness. Vortex (ranger) — stealth mode for massive ranged damage bursts. Nebula (mage) — damage/mana/life boosters snowball your power. Stardust (summoner) — Stardust Guardian for free extra DPS. All 4 sets craft at Ancient Manipulator with Luminite Bars + class Fragments.

Your DPS on the core is too low. Once all 3 eyes are destroyed, the core (50,000 HP, 70 DEF) starts regenerating. If your damage output doesn't exceed the regen rate, it heals back. Fix: save all burst for core phase — pop Wrath/Rage Potion right before the core opens, switch to your highest-DPS weapon, and ignore the floating True Eyes unless they block your aim. Solar Eruption through walls or Phantasm + Holy Arrows are the best core-phase burst options.

After killing the 4th Celestial Pillar, there's a 1-minute countdown before Moon Lord appears. The screen goes dark, the message "Impending doom approaches..." shows up, and you get 60 seconds to prepare. If you died during that countdown, Moon Lord still spawns — get back to your arena fast. If nothing happened, check that all 4 pillars are actually dead (Solar, Vortex, Nebula, Stardust). You can also skip the pillars entirely by crafting a Celestial Sigil at the Ancient Manipulator (12 of each fragment).
