  "textContent": "Crystal Coins are the gatekeeper currency for the Anti-Magic content in Sailor Piece, funding the Anti Magic sword, the Destroyer Aura, the Clover Outfit, and every permanent stat upgrade tied to Crystal Defense. They drop from one place only, and the grind is long enough that build choice and run consistency matter more than raw playtime.\n\n⚡\n\nQuick answer: Run Crystal Defense on Punch Island in Sea 2. Each cleared wave pays 1–4 Crystal Coins, and you need 43,350 coins total to max every permanent stat upgrade.\n\nImage credit: __Roblox (via YouTube/@ViewSIM)__\n\n* * *\n\n### Where Crystal Defense is and what you need to enter\n\nCrystal Defense sits on Punch Island in Sea 2. From the Punch Island spawn, take the left road past the Fast Ninja NPCs and continue straight, northwest of the Cosmic Being world boss. Three NPCs and a leaderboard mark the spot: the Defense Merchant, the Defense Upgrades NPC, and the run starter.\n\nEntry costs one Crystal Key per attempt. Keys drop from NPCs across Sea 2 at a low rate, so you will want a stockpile before settling in for a long session. Up to four players can join a single run.\n\nCrystal Defense sits on Punch Island in Sea 2 | Image credit: __Roblox (via YouTube/@ViewSIM)__\n\n* * *\n\n### How Crystal Coins drop\n\nYou earn Crystal Coins by clearing enemy waves while keeping the central crystal alive. Each wave pays out 1 to 4 coins, and the per-wave payout scales as you push deeper floors. Higher Luck increases the coin roll within that range, but Luck does not affect boss loot drops inside Crystal Defense, so a pure damage build is the correct choice for coin farming.\n\nEvery fifth floor spawns a boss with a chance to drop the Anti Magic sword, the Demon Wings accessory, and the Demon Dweller title. Those drops scale with Luck on the bosses themselves, but coin throughput is a function of how fast you clear waves.\n\nYou earn Crystal Coins by clearing enemy waves | Image credit: __Roblox (via YouTube/@ViewSIM)__\n\n* * *\n\n### Best build and weapons for clearing waves\n\nRun your highest pure-damage loadout. Drop-rate setups are a trap here because Crystal Defense coin and item rolls inside the run favor damage uptime over Luck. Wide AoE V-skills are the priority because enemies spawn from multiple lanes and rush the crystal at once.\n\nWeapon / Fruit| Why it works\n---|---\nIce Queen| Long-range V with fast cooldown, knocks enemies back from the crystal.\nCosmic Being| Large purple AoE on V, strong single-cast clears.\nThe World| High damage AoE, useful for boss waves on floor multiples of 5.\nDragon Goddess| Wide V-skill arc that covers spawn lanes.\n\nKing of Heroes was previously a popular pick for stationary farming, but the V-skill now drifts the character forward after casting. It still works if you face a solid wall or the crystal itself to block movement, but the listed weapons above are safer for AFK setups.\n\nImage credit: __Roblox (via YouTube/@ViewSIM)__\n\n* * *\n\n### AFK setup for overnight farming\n\n**Step 1:** Stockpile Crystal Keys on Sea 2 Starter Island. Equip a luck build, stand on the central spawn marker, and spam an instant-cooldown wide attack to one-shot spawning NPCs. Keys drop alongside Relic Parts during this farm.\n\n**Step 2:** Enter Crystal Defense and position yourself on top of the crystal with one of the wide-AoE weapons listed above. Set your V-skill to auto-fire so the ability cycles on cooldown without input.\n\n**Step 3:** Open the run settings and enable Auto Replay. When the crystal eventually falls, the game spends one Crystal Key and restarts the run automatically. Pick a comfortable target floor so the loop fails predictably rather than stalling on impossible waves.\n\n⚠️\n\nNote: Auto Replay can occasionally hang. Check on the session periodically and confirm your key stockpile is large enough to cover the planned runtime.\n\nImage credit: __Roblox (via YouTube/@ViewSIM)__\n\n* * *\n\n### What Crystal Coins buy\n\nTwo NPCs spend the currency: the Defense Merchant for items and the Defense Upgrades NPC for permanent stat increases. Anti Magic at 5,000 coins is the headline purchase for unlucky players who never see the boss drop, while the Destroyer Aura and Clover Outfit are the next priority cosmetics with stat value.\n\nItem| Price (Crystal Coins)\n---|---\nCommon Chest| 1\nRare Chest| 5\nEpic Chest| 12\nLegendary Chest| 25\nMythical Chest| 65\nSecret Chest| 500\nBoss Key| 3\nDungeon Key| 3\nTower Key| 8\nTrait Reroll| 4\nRace Reroll| 4\nClan Reroll| 9\nBloodline Stone| 14\nClover Outfit| 850\nAura Crate| 1,000\nCosmetic Crate| 1,400\nDestroyer Aura| 2,000\nAnti Magic| 5,000\n\n* * *\n\n### Permanent upgrade costs to max every stat\n\nThe Defense Upgrades NPC sells five stat tracks, each with five levels and escalating costs. Maxing every track requires 43,350 Crystal Coins. Damage and Luck are the priority pulls because Damage compounds your wave clear speed, and Luck improves boss loot rolls outside the run.\n\nStat| L1| L2| L3| L4| L5| Total| Max bonus\n---|---|---|---|---|---|---|---\nDamage| 850| 1,150| 1,500| 2,000| 3,000| 8,500| +25%\nCrit Damage| 850| 1,150| 1,500| 2,000| 3,000| 8,500| +15%\nCrit Chance| 850| 1,150| 1,500| 2,000| 3,000| 8,500| +5%\nHP| 600| 750| 1,000| 1,250| 1,750| 5,350| +37.5%\nLuck| 1,250| 1,750| 2,250| 3,000| 4,250| 12,500| +15%\nThe Defense Upgrades NPC sells five stat tracks | Image credit: __Roblox (via YouTube/@ViewSIM)__\n\n* * *\n\n### Build pieces that speed up the grind\n\nBloodline and Clan rerolls pay for themselves over a long farm. Demonic Bloodline grants 32% damage and a 12% sword damage multiplier, edging out Astral for sword builds. Devil Clan provides 42% damage, 12% sword damage, and a luck boost that beats Eminence for sword players who still want drop-rate value while farming keys outside the tower.\n\nVerifying that everything is configured correctly is straightforward. Open the Stats menu before voting to start, confirm your damage percentage is on your saved damage build, and check that Auto Replay is ticked in the run settings. If the Defense Upgrades NPC shows your stat track at level 5 with no further upgrade option, that track is maxed.",
