The Anti Magic update for Sailor Piece adds a new defense-style game mode on Punch Island, a fresh sword inspired by Black Clover's Asta, a Demon Wing accessory, the Demon Dweller title, and a batch of redeemable codes. The core loop runs through Crystal Keys, Crystal Coins, and the Crystal Defense portal located in C2.
Where to start: Punch Island in C2
All new content is anchored to Punch Island in Sea 2 (C2). Teleport using the island menu and pick Punch Island, which is set in a modern city environment. The new area sits on the left side of the map and contains the Defense Merchant, Defense Upgrades NPC, the Crystal Defense portal, and a leaderboard for the mode.
A timer was also added for the Cosmic Being world boss spawn, so there's no need to guess its arrival window anymore.
How to get Crystal Keys
Crystal Keys are the entry item for the new mode. They drop randomly from any NPC in Sea 2, which includes Punch Island, Bizarre Island, and Starter Island Sea 2. Drop chance scales with your luck stat, so a luck-focused build will produce keys faster than a pure damage setup.
For AFK farming, position your character between mob spawns and bind a wide AOE move on auto. Quake-fruit waves work well from the center of a spawn cluster, and any cleave melee setup with enough power upgrades will keep clearing while you're idle. If your fruit is doing zero damage, your power stat is too low for that NPC tier.
Crystal Defense mode rules
Crystal Defense is a wave-based tower defense variant. You spawn into an arena with a single crystal in the middle, and enemy NPCs ignore you entirely - their only target is the crystal. If the crystal's health hits 0%, the run ends.
Each cleared wave drops Crystal Coins, and a boss spawns every 5 waves. The boss is what rolls for the headline rewards.
| Detail | Value |
|---|---|
| Entry cost | 1 Crystal Key per run |
| Boss interval | Every 5 waves |
| Anti Magic drop rate | 0.3054% |
| Demon Wing drop rate | 0.8815% |
| Fail condition | Crystal health reaches 0% |
| Replay option | Auto Replay toggle, costs 1 key per attempt |
Damage builds clear waves faster, but survivability for the crystal matters more than personal DPS. Position yourself directly on top of the crystal so your AOE intercepts mobs before they touch it.
Best loadouts for AFK Crystal Defense
Two abilities perform well for hands-off runs. Cosmic Being's V move covers a huge radius around the player, large enough that mobs cannot reach the crystal at all if you stand on it. Runs into the wave 50 range have been completed with this setup on auto.
Ice Queen with the V move is the other strong pick, particularly for early-to-mid waves. It clears packs efficiently and works well with luck/damage hybrid builds for boss-drop attempts.
Before starting, open the settings menu and confirm your Half LUCK/DAMAGE, LUCK, and Sword Damage toggles match your goal. Equip your highest-damage sword in the Melee tab.
Two ways to get the Anti Magic sword
You can either farm the boss drop or save coins for a guaranteed purchase. The drop route is fastest if RNG cooperates, but the deterministic path is the Defense Merchant on Punch Island.
| Method | Cost | Notes |
|---|---|---|
| Boss drop in Crystal Defense | Crystal Keys + RNG | 0.3054% per qualifying boss kill |
| Defense Merchant purchase | 5,000 Crystal Coins | Guaranteed, earned from Crystal Defense waves |
| Robux shop bundle | 1,299 Robux | Includes Anti Magic + Demon Wing |
The Robux bundle is the only way to instantly grab both the sword and the Demon Wing accessory together. Otherwise, the Demon Wing is a separate boss drop at 0.8815%.
Defense Merchant inventory
The Defense Merchant on Punch Island sells the following with Crystal Coins:
| Item | Crystal Coin cost |
|---|---|
| Anti Magic (sword) | 5,000 |
| Destroyer Aura | 2,000 |
| Clover Outfit | 850 |
| Trait Reroll | Listed |
| Race Reroll | Listed |
| Clan Reroll | Listed |
The separate Defense Upgrades NPC accepts Crystal Coins for permanent stat bumps - DAMAGE %, CRIT DAMAGE, CRIT CHANCE, HP %, and LUCK. Maxing these out takes a long grind, similar to Boss Rush and Infinite Tower upgrade tracks.
Anti Magic abilities
The sword uses Black Clover-inspired animations across its five ability slots. Each one has a full cutscene when cutscenes are toggled on in settings.
| Key | Type |
|---|---|
| Z | Forward slash attack |
| X | Ranged sword projectile |
| C | Spinning AOE - useful for AFK clearing |
| V | Large cinematic finisher |
| F | Heavy single-target strike |
Demon Dweller title
Demon Dweller is the new strongest title and drops from Crystal Defense boss kills. It grants +100% damage, making it the highest-impact title currently in the game. Equip it from the Titles menu once it drops.

Other additions in this patch
Beyond Crystal Defense itself, the update introduces a new clan, a new bloodline, two accessories, two auras, the Demon Dweller title, the Anti Magic sword, the Punch Island shop, and the Crystal Defense leaderboard. The Cosmic Being timer is a quality-of-life addition that helps coordinate world-boss spawns.
Trading was disabled at launch, so duplicate Anti Magic drops cannot currently be sent to other players. Check the in-game trade menu before assuming a trade will go through.
The fastest path to a finished Anti Magic build is straightforward. Farm Crystal Keys with a luck setup on any C2 island, run Crystal Defense with Cosmic Being or Ice Queen on top of the crystal, and bank Crystal Coins until you can buy the sword outright. Boss drops are a bonus on the way - the 5,000-coin purchase guarantees the weapon regardless of RNG.
