In Crystal Defense, you can defend a central crystal against waves of enemies. Moreover, it’s the main way to earn Crystal Coins, a special currency used for purchasing rare items. So, if you want to know more about it, here’s a complete guide on Crystal Defense on Sailor Piece.
How to Enter Crystal Defense Mode in Sailor Piece
Crystal Defense can be accessed on Punch Island in Sailor Piece, but before heading there, you will first need to unlock Sea 2. Once you gain access, use the portal to travel to Punch Island. After arriving, take the path on the left side of the island. Continue walking straight past them, and you will eventually come across the Crystal Defense NPCs.
So, to participate in Crystal Defense, you must have Crystal Keys. These keys are earned by defeating all NPCs found throughout Sea 2, so make sure you clear them out before attempting the mode. Once you have at least one key, head back to Punch Island and interact with the Crystal Defense NPC positioned on the right.
After interacting with the NPC, select the ‘Spawn’ option to create a Crystal Defense portal. A short timer will begin, and the challenge will automatically start once it ends. If you are ready, you can skip the wait by pressing the ‘Start’ button.
How Crystal Defense Mode Works in Sailor Piece
A Crystal Defense run in Sailor Piece begins only after everyone has voted to start. The core objective is to protect the central crystal, which starts at full health. Waves of enemies will continuously spawn and rush toward it, and your role is to eliminate them before they can chip away at its HP.
As the run progresses, each wave introduces a random debuff that makes survival more challenging. Additionally, every fifth wave brings a boss fight, and defeating these bosses can reward you with rare items like the Anti Magic Sword, Demon Wings accessory, and the Demon Dweller title, with drop chances becoming more frequent based on your luck.
If the crystal is destroyed, the run ends instantly, and you will be prompted to restart by spending a Crystal Key. You can also enable auto-spawn through the settings. For every wave you clear, you earn Crystal Coins, usually between one and four per wave, with higher luck helping you earn more.
