Unlocking the Calamity Fist in Heian is a high-reward challenge for players looking to master one of the most powerful cursed weapons in the game. This secret fist weapon not only delivers raw melee strength but also grants automatic Black Flash effects on combo attacks, making it a top-tier choice for aggressive builds. In this guide, we’ll explain how to get Calamity Fist in Heian, including how to trigger the quest, all Calamity boss locations, stat requirements, and the full breakdown of its unique attack effects.
What Is Calamity Fist in Heian?
Calamity Fist is a special weapon that transforms your basic M1 attacks into a three-part combo, each imbued with automatic Black Flash damage. Unlike standard Black Flash, which requires perfect timing, Calamity Fist guarantees the effect, giving players massive burst potential in both PvE and PvP.
To wield it, you must meet these stat requirements:
50 Strength
50 Cursed Energy
These stats can be reallocated using the Dawn Parchment, allowing flexibility if your current build doesn’t align.
How to Trigger the Calamity Fist Quest
The quest to obtain Calamity Fist is completely hidden and begins in a secret location behind Kirisaki Village.
Step-by-Step:
Go to the Hidden Well behind Kirisaki Village.
Enter the well and press the “1” key while inside.
If successful, a message will appear instructing you to defeat three specific Calamity bosses.
The message will only appear if the sequence is done correctly.
From this point, the quest is active, and you can start hunting the bosses.
All Calamity Boss Locations
To complete the quest, you must defeat three Calamity-tier bosses, each located in a different biome. They must be defeated in one life—dying during any of the fights may reset the sequence, especially for the final boss.
1. Tengu (Tundra Biome)
Location: In the snowy Tundra, near the cliffs beyond the temple.
Difficulty: Easy
Tips: Tengu has predictable movement and is soloable by mid-level players.
2. Beast Calamity (Overgrown Valley)
Location: Deep within the Overgrown Valley, in a mossy clearing near the ruins.
Difficulty: Medium
Tips: This boss is slow but powerful. Time your dodges, and stay close to bait out slam attacks.
3. Skull Calamity (Oasis Biome)
Location: Southwest corner of the Oasis biome, behind a cavern entrance.
How to Summon: Pick a red flower nearby and offer it at the altar inside the cave.
Difficulty: High
Warning: If you die during this fight, you cannot retry immediately. This is a one-chance encounter for each run.
Skull Calamity is the most dangerous of the three. Bring strong healing or a friend to assist if needed.
Claiming the Calamity Fist
Once all three bosses are defeated:
A message will appear saying “Promise Fulfilled”
Return to the Hidden Well behind Kirisaki Village
Interact with the center to claim the Calamity Fist
The weapon will be added to your inventory, ready to equip if your stats meet the requirements.
