MegaBonk How to Get Corrupted Sword Guide
The Corrupted Sword is one of the hardest weapons to unlock in MegaBonk. It rewards aggressive players who can survive at low health while dealing massive damage. Here’s exactly how to get it, how its unlock challenge works, and which builds pair best once you have it.
How to Unlock the Corrupted Sword
To unlock the Corrupted Sword, you must upgrade the Cursed Tome to Level 20 within the first 10 minutes of a run. This is a timed challenge that demands early RNG luck, fast leveling, and smart rerolls.
You also need to have the Cursed Tome unlocked first. It becomes available after defeating any stage boss in under five minutes. Once it’s in your item pool, you can attempt the Corrupted Sword challenge.
Start a new run and look for the Cursed Tome in your first few upgrade choices. If it doesn’t appear early, restart until it does. Once you have it, focus entirely on leveling it to 20 as quickly as possible.
Use XP-boosting items and tomes to speed up your leveling. Prioritize anything that increases Experience gain and use Refresh or Banish to clear unwanted upgrades. You must hit Level 20 on the Cursed Tome before the timer reaches 10:00.
After completing the challenge, purchase the Corrupted Sword from the Unlocks tab for 8 Silver.
Corrupted Sword Overview
The Corrupted Sword is a melee cleave weapon that slashes both forward and backward. It scales with Damage, Projectile Count, Knockback, and Size. Its main effect boosts damage massively when you’re at low health, making it one of the strongest late-game weapons in the game for risk-takers.
Best Strategy and Synergies
The Corrupted Sword fits a berserker playstyle. The goal is to stay near death without dying. When your health drops below around 30 percent, the weapon’s damage spikes sharply. This makes it perfect for players who thrive under pressure.
Pairing it with Lifesteal or healing-on-kill effects like Bloody Tome helps you survive in the danger zone while still taking advantage of the low-HP damage bonus.
Athena is the best character for this weapon. Her passive increases damage at low HP, and it stacks with the Corrupted Sword’s boost. The combination turns her into one of the highest damage dealers in MegaBonk.
Defensive items like temporary shields or short invulnerability bursts are also valuable. They let you play close to death without instantly losing your run.
Upgrade Path
The Corrupted Sword can upgrade in four key stats when leveled up:
Damage
Projectile Count
Knockback
Size
Each upgrade makes the weapon’s slashes faster, wider, and stronger, giving it some of the best melee coverage in the game.
Final Blurb
The Corrupted Sword is a high-skill weapon that rewards speed, precision, and confidence. Unlocking it requires one of the hardest timed challenges in MegaBonk, but once earned, it becomes one of the most powerful tools for low-health builds.
