At very high Size, sword projectile travel now scales correctly instead of becoming incorrectly slow. The forward swing can also damage multiple enemies rather than stopping after one target. Size and Quantity therefore provide dependable coverage, not just a larger visual arc.

🏗️ Recommended Setups
Build ideas based on real, widely used items/tomes
💢 Berserker Core
🎯 Core Strategy
Dip to low HP for bonus damage windows, then sustain back up. Great when you can control risk.
📚 Tomes
- Damage • Size • Cooldown • Quantity
🎒 Items (examples)
- Anvil, Sucky Magnet, Boss Buster
- Demonic Soul, Chonkplate, Gym Sauce
- Oats, Medkit, Clover, Time Bracelet
⚡ Tips
- Don’t stay at 1 HP—cycle windows safely
- Use Size/Quantity to cover your flanks
- Pick a ranged secondary (e.g., Dexecutioner/Katana) early
🛡️ Safer Chadwell
🎯 Core Strategy
Use survivability items while scaling Size/Cooldown so twin slashes cover more space and swing faster.
📚 Tomes
- Size • Damage • Cooldown • Quantity
🎒 Items (examples)
- Oats, Medkit, Beefy Ring
- Anvil, Demonic Soul
- Shrine utility: Boss Buster
⚡ Tips
- Prioritize early safety, then pivot to damage
- Greed shrines only when you’re comfortably clearing
⏱️ Cursed Tome Rush
🎯 Core Strategy
Limit Weapon/Tome slots to improve roll odds; run Hyper Desert; chain a late Magnet for mass XP.
📚 Tomes
- Cursed • XP (toggle off most others)
🎒 Items / Picks
- Sucky Magnet, Anvil
- Any strong early clearer (e.g., Revolver, Aura)
⚡ Tips
- Use rerolls/banish to force Cursed Tome levels
- Save a Magnet shrine for minute 8–9 XP sweep
- Tony McZoom is popular for speed & shield
👥 Character Synergy
Who commonly pairs well and why
👑 Sir Chadwell
Begins with Corrupted Sword; plan for a slow start then scale.
🏎️ Tony McZoom
Movement speed & shield make the Cursed Tome challenge easier.
🧛 Vlad
Sustain supports controlled low-HP windows.
🥷 Ninja
Mobility helps positioning for melee coverage.
🦊 Fox
Solid fundamentals; flexible itemization.
🛡️ Athena
Low-HP damage themes can pair well with the sword’s passive.
🧠 Advanced Tips
Practical notes from community-proven runs
🎛️ Limit Slots
Refund to ~2 Weapon / 2–3 Tome slots so Cursed Tome appears more often during level-ups.
⛏️ Save a Magnet
Clear safely, then grab a Magnet shrine late to jump several tome levels at once.
🗺️ Hyper Desert Route
Hyper Desert Tier 1 is popular for XP density; if damage falls off, downshift to safer tiers.
🪓 Ranged Partner
Early ranged weapons (Dexecutioner, Katana, Aura) stabilize clears while the sword scales.
⚖️ Play the Edge
Use the low-HP bonus, but keep sustain handy to avoid sudden deaths during swarms.
🔁 Banish & Reroll
Banish non-critical tomes; reroll aggressively for Cursed/XP picks during the challenge.
⚖️ Corrupted Sword vs Similar Weapons
Where it fits
🗡️ vs Sword / Hero Sword
Sword is basic melee; Hero Sword adds a projectile. Corrupted Sword adds twin slashes and low-HP damage, rewarding riskier play.
🪓 vs Dexecutioner
Dexecutioner excels at finishing tougher enemies consistently. Corrupted Sword spikes harder when you manage HP windows well.
❓ Corrupted Sword FAQ
Name, unlock and build questions
Is Cursed Sword the same as Corrupted Sword?
Yes. “Cursed Sword” is a common search name, but Corrupted Sword is the in-game weapon name. Do not confuse it with Cursed Tome, which is a separate tome required for the unlock challenge.
How do I unlock Corrupted Sword?
Unlock Cursed Tome by defeating a Stage Boss in under 5 minutes. In a later run, level Cursed Tome to 20 before the timer reaches 10:00, then purchase Corrupted Sword with Silver in the Unlocks menu.
Do I need Sir Chadwell?
No. Sir Chadwell starts with Corrupted Sword, but completing Forest Tier 3 unlocks the character, not the weapon. The sword uses the Cursed Tome challenge above.
What is the best Corrupted Sword build?
Prioritize Damage, Size, Cooldown and Quantity. Size expands both slash lanes, Cooldown increases attack frequency, and a ranged secondary makes the early close-range phase safer. See the Sir Chadwell build for a full sword-focused variant.
