Illusion Prism is a crafting material in Sailor Piece required for obtaining the Aizen Sword, one of the best Mythical-tier weapons in the game. This item only drops from a specific boss with a moderate drop rate, making it a grind-heavy material to farm. Getting enough Illusion Prisms requires defeating the same boss repeatedly and using efficient farming methods. Here's how to get Illusion Prism in Sailor Piece and what to use it for.
How to Get Illusion Prism in Sailor Piece
Travel to Hollow Island through any teleporter on the map. Open the teleporter menu and scroll to find the Hollow option. This island is the only location where you can farm Illusion Prism, so you'll spend significant time here while grinding for this material.
Find and defeat the Aizen boss/Manipulator on Hollow Island. This boss is the only source of Illusion Prism in Sailor Piece. The boss spawns in a fixed location on the island, making him easy to locate once you arrive. Aizen has a 14.4% drop rate for Illusion Prism. This drop rate isn't extremely rare compared to other boss materials, but it's not guaranteed either. You might get lucky and receive an Illusion Prism on your first few kills, or you might need 10-20 attempts before seeing a single drop.
Equip a luck build before fighting the boss to increase your drop chances. Use titles like Celestial Favor, Destiny Marked, or Blessed Sovereign for maximum luck bonuses. Higher luck doesn't guarantee drops but improves your chances compared to farming with zero luck bonuses.
The boss respawns every 5 minutes after being defeated. If you stay in one server and wait for each respawn, your farming efficiency drops significantly. Waiting 5 minutes between each kill means you only get 12 attempts per hour at the 14.4% drop rate.
Use of the Illusion Prism in Sailor Piece
Illusion Prism is required to craft the Aizen Sword from the Manipulator Trainer NPC on Hollow Island. This Mythical-tier sword ranks among the best weapons in Sailor Piece and requires significant materials to obtain. The complete crafting recipe for the Aizen Sword includes:
| Material | Amount Required |
|---|---|
| Cash | 6,000,000 |
| Gems | 10,000 |
| Mirage Pendant | 10 |
| Illusion Prism | 6 |
| Reiatsu Core | 3 |
| Hogyoku Fragment | 1 |
You need 6 Illusion Prisms total to craft the sword. This requirement means you'll spend considerable time farming Aizen. At 14.4% drop rate, expect to kill Aizen/Manipulator 40-50 times on average to collect all 6 Illusion Prisms.
Additional requirements include completing specific Aizen Trainer quests before you can purchase the sword. These quests involve killing enemies, dealing damage, and defeating the boss multiple times. For more guides, check out our Sailor Piece wiki.
