What is the best way to farm for the Last Prism in Terraria?

Farming for the Last Prism in Terraria is a challenging but rewarding task, as it is one of the most powerful magic weapons in the game. The Last Prism is dropped by the Moon Lord, the final boss of Terraria, with a 11.11% drop rate. To efficiently farm for this weapon, you need to prepare thoroughly, optimize your combat setup, and understand the mechanics of the Moon Lord fight. HereÔÇÖs a detailed guide to help you achieve this.

First, you need to ensure you are in the endgame stage of Terraria. This means you should have defeated all other bosses, including the Lunatic Cultist and the Celestial Pillars, which are prerequisites for summoning the Moon Lord. You should also have access to powerful gear, weapons, and accessories that are suitable for the Moon Lord fight. The Moon Lord is a tough opponent, so preparation is key.

To summon the Moon Lord, you can either defeat the Celestial Pillars or use a Celestial Sigil. The Celestial Sigil is crafted using 20 Solar Fragments, 20 Nebula Fragments, 20 Vortex Fragments, and 20 Stardust Fragments at an Ancient Manipulator. Using the Celestial Sigil is more efficient for farming, as it allows you to skip the Celestial Pillars phase and directly summon the Moon Lord.

For the fight itself, you need to create a suitable arena. A long platform with multiple layers of wooden platforms is ideal. This allows you to move freely and dodge the Moon LordÔÇÖs attacks. Place heart lanterns, campfires, and honey pools around the arena to provide health regeneration. You can also use heart statues wired to timers for additional healing. Buff stations like the Bast Statue and Star in a Bottle can further enhance your survivability and damage output.

In terms of equipment, the best class for farming the Moon Lord is the magic class, as the Last Prism is a magic weapon. However, you can also use other classes if you prefer. For magic users, the Nebula Armor is the best choice, as it provides significant magic damage bonuses and health regeneration. Equip accessories like the Celestial Emblem, Sorcerer Emblem, and Mana Flower to boost your magic damage and mana efficiency. The Celestial Cuffs or Mana Cloak can help with mana regeneration. Wings, such as the Fishron Wings or BetsyÔÇÖs Wings, are essential for mobility. The Master Ninja Gear or Shield of Cthulhu can help with dodging attacks.

For weapons, the Nebula Blaze and Razorblade Typhoon are excellent choices for dealing consistent damage to the Moon Lord. The Last Prism itself is the ultimate goal, but you can use other powerful magic weapons until you obtain it. For other classes, the Solar Eruption (melee), Phantasm (ranged), and Stardust Dragon Staff (summoner) are strong alternatives.

Buff potions are crucial for the Moon Lord fight. Use potions like the Magic Power Potion, Mana Regeneration Potion, Endurance Potion, Ironskin Potion, and Lifeforce Potion to enhance your combat effectiveness. The Well Fed buff from food items like Pumpkin Pie or Seafood Dinner is also helpful.

During the fight, focus on the Moon LordÔÇÖs eyes and core. The True Eyes of Cthulhu will spawn after the eyes are destroyed, so prioritize them next. Keep moving to avoid the Moon LordÔÇÖs laser attacks and projectiles. Use your platforms to create distance and dodge effectively. Healing potions should be used sparingly, as they have a cooldown period. Instead, rely on your arenaÔÇÖs healing stations and buffs.

Common mistakes to avoid include standing still for too long, which makes you an easy target for the Moon LordÔÇÖs attacks. Also, avoid using weapons with slow projectiles, as they may miss the Moon LordÔÇÖs moving parts. Ensure your arena is well-lit and free of obstacles to prevent accidental deaths.

Advanced techniques include using the Rod of Discord to teleport away from dangerous attacks, though this requires precise timing. You can also use the Nurse NPC for emergency healing, but this is risky as the Moon Lord can kill her quickly.

In summary, farming for the Last Prism requires thorough preparation, a well-designed arena, and a strong combat setup. Focus on optimizing your gear, using buffs, and mastering the Moon LordÔÇÖs attack patterns. With persistence and the right strategy, you will eventually obtain the Last Prism and wield one of the most powerful weapons in Terraria.
