How to Get Anti Magic Sword in Sailor Piece? 2026 Guide

If you’re trying to figure out how to get Anti Magic in Sailor Piece, you’re in the right place. This is the new Asta-inspired sword that just dropped with the Anti-Magic update, and trust me, it’s stupidly strong. I’ve been grinding it nonstop, so here’s the cleanest path I’ve found, plus all the tips I wish someone told me on day one.

Here’s what I’ll cover in this guide:

• Every way to unlock the Anti Magic sword (free + paid)
• The full Crystal Defense farm loop (the only place this thing drops)
• Best builds and abilities for clearing waves fast
• Drop rates, prices, and which method is actually worth it
• Pro tips, mistakes I made, and AFK tricks

I’ve spent way too many hours running Crystal Defense over the past few days, dying to wave bosses, restarting, getting baited by the boss drop, and finally banking the coins. I’ll save you the headache.

Quick Overview: What Is the Anti Magic Sword?

Sailor Piece is one of those Roblox anime mashups that pulls from One Piece, Naruto, Jujutsu Kaisen, and now Black Clover. The whole game is about sailing between islands, grinding mobs, beating bosses, and chasing rare swords and fruits. It’s been blowing up since Sea 2 dropped, and the player count keeps climbing.

The Anti Magic sword itself is the new Mythical-tier weapon from the April 26, 2026 update. It’s straight-up Asta’s Demon Slayer blade from Black Clover — same massive black sword, same energy. In-game, it hits like a truck. M1s alone do millions of damage with a decent build, and the F move? It’s one of the strongest single abilities in the entire Sea 2 endgame right now.

Here’s why everyone’s chasing it:

• Mythical rarity (highest tier in the game)
• Five moves unlocked instantly — Z, X, C, V, and F, no mastery grind
• Massive AoE on most abilities
• Pairs with Demon Wings accessory and Demon Dweller title for a full Asta build

I picked it up after about 9 hours of farming, and honestly it changed my whole loadout. My old sword went straight in the box.

How to Get Anti Magic in Sailor Piece (3 Methods)

There are basically three ways to get the Anti Magic sword. One is free and slow, one is free and lucky, and one costs Robux. Here’s the breakdown.

Method 1: Buy It With 5,000 Crystal Coins (The Guaranteed Free Way)

This is the one I went with, and it’s the route I’d recommend to literally anyone. No RNG, no gambling, you just farm until you can afford it.

You need 5,000 Crystal Coins, and Crystal Coins only drop from the Crystal Defense game mode on Punch Island. You earn 1 to 4 coins per wave you clear, plus chunks from boss kills. Once you’ve banked 5K, you walk up to the Defense Merchant on Punch Island, hit the yellow 5.0K button under Anti Magic, and the sword goes straight to your inventory with all five moves unlocked.

Method 2: Lucky Boss Drop in Crystal Defense

This is the gamble route. Every 5 waves in Crystal Defense, a boss spawns. Each boss kill rolls for Anti Magic, Demon Wings, and the Demon Dweller title. The drop rates are rough though:

• Anti Magic: ~0.3% base, scaling up to ~0.76% on deep waves (90+)
• Demon Wings: ~0.88%
• Demon Dweller title: rare drop, scales with luck

The drop chance climbs the deeper you push, so deep runs are way better than restarting at wave 10 over and over. If you’ve got a luck build and patience, you might get lucky. I didn’t. After like 30 boss kills with zero drops, I gave up and just farmed coins instead.

Method 3: Robux Shop (Skip the Grind)

If you’re impatient and don’t mind spending real cash, the in-game shop sells Anti Magic for 1,499 Robux standalone, or there’s a bundle with the Demon Wing accessory for 1,299 Robux. The bundle is actually the better deal since it’s cheaper and gets you the wing too.

I personally don’t recommend this — the grind isn’t that bad once you’ve got a setup — but the option’s there.

Step-by-Step: How to Farm Anti Magic the Free Way

Okay, here’s the actual gameplay loop. Follow this in order:

Step 1: Unlock Sea 2

You can’t even touch Anti Magic until you’ve made it to Sea 2. To unlock it, you need to:

1. Reach Level 12,500 or higher
2. Hit Ascension V
3. Complete the Sea Traveler questline (Ancient + Map Fragments)

If you’re not there yet, grind Sea 1 bosses and get those quests done first.

Step 2: Farm Crystal Keys

Crystal Keys are your ticket into Crystal Defense, and you need them on every run (including restarts after a fail). They drop randomly from any NPC in Sea 2, but the drop rate is brutal — like, very low.

My tip: Go to Starter Island in Sea 2. The NPCs there have low HP and spawn in dense clusters, so a luck build can chew through them way faster than fighting tankier enemies on other islands. Punch Island works too if you want to be near the portal, but Starter Island is faster per kill in my experience.

Equip a luck build for this step — luck stacks help with key drops too.

Step 3: Head to Punch Island

Once you have at least one Crystal Key, teleport to Punch Island using the island menu. Punch Island is a city-themed map. Take the road on the left, push past the Fast Ninja NPCs, and you’ll find:

• Defense Merchant (where you’ll buy the sword later)
• Defense Upgrades NPC (permanent stat upgrades)
• Crystal Defense portal (the entrance to the mode)
• Leaderboard

Step 4: Run Crystal Defense

Talk to the Crystal Defense NPC, spend a Crystal Key, and you’re in. Here’s how the mode works:

• One crystal in the middle of the arena, starts at 100% HP
• Mobs spawn in waves and rush the crystal — they ignore you completely
• Each cleared wave drops Crystal Coins (1-4 per wave)
• A boss spawns every 5 waves
• Each level applies a random debuff (half damage, longer cooldowns, etc.)
• If the crystal hits 0%, your run ends. Restart costs 1 Crystal Key.

Here’s the thing — your job isn’t to fight enemies, it’s to protect the crystal. So don’t go chasing mobs across the arena. Stand directly on top of the crystal. Your AoE attacks will intercept everything before it reaches the crystal.

Step 5: Push as Deep as You Can

Each wave gives 1–4 coins, so you want long runs, not short ones. The deeper you push, the more coins per Crystal Key, and the higher the boss drop rate climbs. People have reported runs into wave 50+ on AFK setups, and wave 90+ if you’re actively playing with a tuned damage build.

Step 6: Buy the Sword

Once you’ve stacked 5,000 Crystal Coins, head back to the Defense Merchant on Punch Island. Open the menu, scroll to Anti Magic, click the yellow 5.0K button. Done. The sword’s in your inventory.

2026 Best Builds and Picks for Crystal Defense

I tested a bunch of setups, and these are the ones that actually carry runs:

My Top Builds for Crystal Defense

1. Cosmic Being (V move) — The V move covers a massive radius around your character. If you stand on the crystal, mobs literally cannot reach it. I’ve seen people AFK to wave 50 with just this.
2. Ice Queen sword — Pushes enemies back and slows them. Great for crowd control on tight waves.
3. The World (sword) — Strong AoE, freezes mobs in place. Pairs great with a damage build for boss waves.
4. Quake fruit — Big AoE knockback, classic crystal defender.
5. Soul fruit — Decent damage and good ability uptime for sustained pressure.
6. Dragon Goddess sword — If you’ve got it, it absolutely melts boss waves.
7. Best damage relics — Stack damage % and crit damage relics over luck for boss-drop hunting.

Crystal Coin Shop Items Worth Buying After Anti Magic

Once you’ve got the sword, save your future Crystal Coins for these:

• Destroyer Aura — 2,000 coins, big damage boost
• Aura Crate — 1,000 coins, RNG aura roll
• Clover Outfit — 850 coins, completes the Asta cosplay
• Defense Upgrades — permanent stat bumps (DAMAGE %, CRIT DAMAGE, CRIT CHANCE, HP %, LUCK)

Maxing all the Defense Upgrades costs around 43,350 coins total, so it’s a long-term goal.

Tips & Strategies for Crystal Defense Grinding

Some stuff I learned the hard way:

• Don’t chase mobs. Stay parked on the crystal. The mobs come to you.
• Toggle off cutscenes in settings before starting. Anti Magic moves have full cutscenes that mess with your timing.
• Toggle Sword Damage on in settings if you’re using a sword-focused build. Some toggles default off.
• Use auto-restart — type in the highest level you can clear, turn auto-spawn on, and you can AFK farm coins overnight (assuming you have enough Crystal Keys stocked).
• Damage build > Luck build for deep runs. Luck helps drops, but if you can’t survive deeper waves, you’re not getting bosses anyway. Push depth first.
• Redeem codes before grinding. Codes like ANTIMAGICUPDATE, CRYSTALDEFENSE, and 1MLIKESWOAHHH give boosts that stack on your farm. Free damage and luck = faster grind.
• Stockpile Crystal Keys before a long session. Nothing worse than getting a clutch run going and running out of keys after one death.
• Boss waves = burst windows. Save your highest-damage abilities for wave 5, 10, 15, etc. so you can melt bosses fast and reduce the chance they hit the crystal.

Pro Tips (Advanced Players)

If you’re already deep into Sailor Piece, here’s the meta tech for Anti Magic farming:

• Cosmic Being on auto-restart is the strongest hands-off setup right now. V move covers the whole crystal radius, and you can clock 50+ wave runs while doing literally nothing.
• Stack the Demon Dweller title if you get it. +100% damage is the highest single multiplier in the game right now.
• Pair Anti Magic with Demon Wings for the full Asta theme — Demon Wings adds movement and damage stats, which compound nicely with the F move’s hit count.
• Defense Upgrades have a soft pity feel — the higher your maxed stats, the deeper you can push, which feeds back into more coins per key. Prioritize HP % and DAMAGE % first.
• F move cooldown management. The F move is your nuke. Don’t waste it on trash waves — save it for the boss every 5 waves.
• Server hop for low-pop servers when farming Crystal Keys. Empty servers = less competition for Sea 2 NPCs.
• Pair luck relics with luck-boosting auras when farming Crystal Keys specifically. Then swap to damage relics for Crystal Defense itself.

Conclusion

That’s basically everything I’ve learned about how to get Anti Magic in Sailor Piece. The cleanest path is: unlock Sea 2, farm Crystal Keys on Starter Island, run Crystal Defense with a Cosmic Being or damage-focused build, stand on the crystal, push deep, bank coins, and hit 5,000 to buy the sword guaranteed. Boss drops are a nice bonus, Robux is for the impatient, but the coin grind is the real route.

Anti Magic is genuinely one of the best swords in the game right now and worth every hour. The F move alone changes how you fight bosses, and stacking it with Demon Wings and the Demon Dweller title makes you stupidly strong.

Let me know in the comments which build you’re rocking with the Anti Magic sword, or if you’ve cleared higher waves than me in Crystal Defense — I’m always looking for tech to push deeper.
