  "textContent": "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.\n\n⚔️\n\nQuick answer: Kill any NPC in C2 to farm Crystal Keys, use a key at the Crystal Defense portal on Punch Island, then either gamble on the boss drop (Anti Magic at 0.3054%) or save 5,000 Crystal Coins to buy the sword from the Defense Merchant.\n\nImage credit: __Roblox (via YouTube/@ViewSIM)__\n\n* * *\n\n### Where to start: Punch Island in C2\n\nAll 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.\n\nA timer was also added for the Cosmic Being world boss spawn, so there's no need to guess its arrival window anymore.\n\nAll new content is anchored to Punch Island in Sea 2 (C2) | Image credit: __Roblox (via YouTube/@ViewSIM)__\n\n* * *\n\n### How to get Crystal Keys\n\nCrystal 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.\n\nFor 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.\n\n🎯\n\nNote: Punch Island is rumored to have a higher key drop rate, but this isn't officially confirmed. Any C2 island works.\n\nCrystal Keys drop randomly from any NPC in Sea 2 | Image credit: __Roblox (via YouTube/@ViewSIM)__\n\n* * *\n\n### Crystal Defense mode rules\n\nCrystal 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.\n\nEach cleared wave drops Crystal Coins, and a boss spawns every 5 waves. The boss is what rolls for the headline rewards.\n\nDetail| Value\n---|---\nEntry cost| 1 Crystal Key per run\nBoss interval| Every 5 waves\nAnti Magic drop rate| 0.3054%\nDemon Wing drop rate| 0.8815%\nFail condition| Crystal health reaches 0%\nReplay option| Auto Replay toggle, costs 1 key per attempt\n\nDamage 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.\n\n* * *\n\n### Best loadouts for AFK Crystal Defense\n\nTwo 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.\n\nIce 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.\n\nBefore 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.\n\nImage credit: __Roblox (via YouTube/@ViewSIM)__\n\n* * *\n\n### Two ways to get the Anti Magic sword\n\nYou 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.\n\nMethod| Cost| Notes\n---|---|---\nBoss drop in Crystal Defense| Crystal Keys + RNG| 0.3054% per qualifying boss kill\nDefense Merchant purchase| 5,000 Crystal Coins| Guaranteed, earned from Crystal Defense waves\nRobux shop bundle| 1,299 Robux| Includes Anti Magic + Demon Wing\n\nThe 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%.\n\nYou can either farm the boss drop or save coins for a guaranteed purchase | Image credit: __Roblox (via YouTube/@ViewSIM)__\n\n* * *\n\n### Defense Merchant inventory\n\nThe Defense Merchant on Punch Island sells the following with Crystal Coins:\n\nItem| Crystal Coin cost\n---|---\nAnti Magic (sword)| 5,000\nDestroyer Aura| 2,000\nClover Outfit| 850\nTrait Reroll| Listed\nRace Reroll| Listed\nClan Reroll| Listed\n\nThe 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.\n\nImage credit: __Roblox (via YouTube/@ViewSIM)__\n\n* * *\n\n### Anti Magic abilities\n\nThe sword uses Black Clover-inspired animations across its five ability slots. Each one has a full cutscene when cutscenes are toggled on in settings.\n\nKey| Type\n---|---\nZ| Forward slash attack\nX| Ranged sword projectile\nC| Spinning AOE - useful for AFK clearing\nV| Large cinematic finisher\nF| Heavy single-target strike\n\n* * *\n\n### Demon Dweller title\n\nDemon 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.\n\n* * *\n\n### Anti Magic update codes\n\nOpen Settings and scroll to the bottom to find the code redemption box. Codes are case-sensitive - enter them exactly as written below.\n\nCode| Reward\n---|---\nthank you for 250k followers event| Multiple items\nbig update next soon| Reward bundle\n600k favorites| Reward bundle (enter in caps)\ncrystal defense| Reward bundle\nanti magic update| Reward bundle\n1 million likes| Reward bundle\nImage credit: __Roblox (via YouTube/@ViewSIM)__\n\n* * *\n\n### Other additions in this patch\n\nBeyond 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.\n\nTrading 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.\n\n* * *\n\nThe 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.",
