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

The Last Prism is one of the most powerful magic weapons in Terraria, and obtaining it requires defeating the Moon Lord, the final boss of the game. Farming for the Last Prism involves repeatedly fighting the Moon Lord to increase your chances of obtaining this rare drop. Here is a detailed guide on how to efficiently farm for the Last Prism, covering mechanics, strategies, and preparation.

First, you need to understand the mechanics of the Moon Lord fight. The Moon Lord is summoned by using a Celestial Sigil, which is crafted from 20 Solar Fragments, 20 Nebula Fragments, 20 Vortex Fragments, and 20 Stardust Fragments. Alternatively, the Moon Lord will automatically spawn after defeating the four Celestial Pillars during the Lunar Events. The Moon Lord has three main parts: the head, the hands, and the core. Each part must be destroyed to defeat the boss. The Last Prism has a 11.11% drop chance from the Moon Lord, so you may need to fight him multiple times to obtain it.

To prepare for farming the Moon Lord, you should focus on building a strong arena and gathering the best equipment. A good arena for the Moon Lord fight includes multiple layers of platforms spaced about 10 blocks apart, allowing you to dodge his attacks more easily. Place Heart Lanterns, Campfires, and Honey Pools around the arena to provide health regeneration. Additionally, consider using traps and teleporters to create a more dynamic and safe fighting environment.

For equipment, the best class for farming the Moon Lord is the Mage class, as the Last Prism is a magic weapon. Use the Nebula Armor set, which 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 reduce mana consumption. Other useful accessories include the Wings, Master Ninja Gear, and Ankh Shield for mobility and defense. Reforge your accessories to Menacing or Lucky for maximum damage or critical strike chance.

In terms of weapons, the Nebula Blaze and Razorblade Typhoon are excellent choices for dealing consistent damage to the Moon Lord. Use the Spectre Staff for homing projectiles and the Lunar Flare for high burst damage. Always carry plenty of Mana Potions and Super Healing Potions to sustain yourself during the fight. Buffs like Magic Power, Mana Regeneration, and Endurance Potions will further enhance your combat effectiveness.

During the fight, focus on destroying the Moon Lord's hands first, as they deal significant damage. Once the hands are down, target the head, and finally, the core. Keep moving to avoid the Moon Lord's Phantasmal Deathray and other attacks. Use the Rod of Discord to teleport out of danger if necessary. After defeating the Moon Lord, collect the loot and check if the Last Prism dropped. If not, repeat the process by summoning the Moon Lord again.

Common mistakes to avoid include not having enough healing items, failing to dodge the Moon Lord's attacks, and not focusing on the correct parts of the boss. Make sure to have a well-prepared arena and practice the fight to improve your dodging skills. Additionally, avoid using weapons with low DPS, as the Moon Lord has a lot of health and requires consistent damage output.

Advanced techniques include using the Nurse NPC to heal during the fight. Set up a small house with a bed near your arena and assign the Nurse to it. During the fight, you can quickly teleport to the Nurse to heal and return to the battle. Another technique is to use the Solar Eruption or Daybreak, which are powerful melee weapons that can deal damage through walls, allowing you to attack the Moon Lord while staying safe.

In summary, farming for the Last Prism in Terraria involves preparing a strong arena, equipping the best Mage gear, and repeatedly defeating the Moon Lord. Focus on destroying the Moon Lord's hands and head first, use buffs and healing items, and practice your dodging skills. With persistence and the right strategy, you will eventually obtain the Last Prism and wield one of the most powerful weapons in the game.
