Excalibur is a 4-Star Sword at the top of the central tower on Jotunheim Island, which costs 3 billion Money, 30 million Gems, three tiers of Sword Pieces, 15,000 Fire Seeds, and 100 Holy Grails. Sword Pieces come from chests during normal play. Sky Keys, required to enter Sky Spire, can be farmed by killing NPC groups. Holy Grails only drop from Floor 41 onward at a 3.45% to 5.05% rate depending on the floor.
Excalibur is one of the most recognizable Sword weapons in Broken Blade, and its AoE attacks make it one of the strongest options for farming large groups of enemies in the late game. The crafting requirements can be quite confusing, especially for beginners. Items like the Holy Grails are the real bottleneck, locked behind the Sky Spire dungeon. So, this guide covers how to get Excalibur with ease.
What Is Excalibur in Broken Blade?
Excalibur is a 4-Star Sword weapon located on Jotunheim Island. The crafting station is at the top of the large central tower on the island. Climb to the peak and interact with it once you have all the required materials. Excalibur is inspired by Saber's legendary weapon from the Fate series and is especially valued for its massive AoE attacks. So, here's how to get Excalibur in Broken Blade.
How Do You Unlock Excalibur in Broken Blade?
If you want to unlock Excalibur, you will have to fulfill seven material requirements. Sword Pieces you can get through chests during regular play, but Holy Grails can only be farmed from Sky Spire. Here's everything else you need:
| Material | Amount Required |
|---|---|
| Money | 3,000,000,000 |
| Gems | 30,000,000 |
| Sword Piece I | 5,000 |
| Sword Piece II | 2,500 |
| Sword Piece III | 1,000 |
| Fire Seeds | 15,000 |
| Holy Grails | 100 |
Step 1 - Collect Sword Pieces
Sword Pieces drop from chests throughout the game. You will likely collect a significant portion of all three tiers without any dedicated runs. Just open chests consistently and let them build up over time.
Step 2 - Farm Sky Keys
Secondly, you will need Sky Keys to enter Sky Spire, and each run costs 30 Sky Keys at the entrance. So, you will need a large stock before attempting the dungeon.
Step 3 - Farm Holy Grails in Sky Spire
Sky Spire is a tower-style survival challenge, and you will need to pay 30 Sky Keys at the entrance to start a run. Holy Grails only begin dropping from Floor 41 onward. Any run that ends before Floor 41 produces zero Holy Grails, regardless of how many floors you cleared.
With 100 Holy Grails required and drop rates between 3.45% and 5.05%, you will need to complete quite a few runs. The drop rate increases from Floor 61 upward, and staying above that threshold speeds up your farm.
| Floor Range | Holy Grail Drop Rate |
|---|---|
| Floor 41-50 | 3.45% |
| Floor 51-60 | 3.45% |
| Floor 61-70 | 5.05% |
| Floor 71-80 | 5.05% |
| Floor 81-90 | 5.05% |
| Floor 91-100 | 5.05% |
NOTE: There is no Holy Grail drop below Floor 41. Do not enter Sky Spire without enough Sky Keys to reach Floor 41 or higher.
Frequently Asked Questions (FAQs)
NPC farming with an AoE weapon is the most efficient method. Regular enemies drop Sky Keys at a small rate per kill, and using a wide-reaching weapon like Dragon Slayer maximizes the number of kills and therefore drop attempts per minute.
Holy Grails only drop from Floor 41 onward. Nothing below Floor 41 produces them regardless of how many bosses you defeat. Surpassing Floor 61 if your build allows it. The drop rate increases from 3.45% to 5.05% at that threshold and stays elevated through Floor 100.
There is no fixed recommendation, but having enough keys for multiple consecutive runs before entering is important. Each run costs 30 keys at the entrance, and Holy Grails require many runs to collect 100.
