How to Find the Echoes of Aincrad Mithril Blade Blueprint
The Mithril Blade blueprint is found in a chest in the Southern Poeni Prairie area. You can visit this area during the Opportunity side quest. After collecting the blueprint, gather the necessary materials and go to a blacksmith to craft the sword.

Mithril Blade Recipe Location
If you’ve already completed the Opportunity side quest, interact with a main terminal and select the quest from the Complete tab. If not, complete the quest as soon as possible because this is how you unlock the costumes function. Replaying the side quest allows you to explore the area where you will find the chest containing the Echoes of Aincrad Mithril Blade blueprint.
From the Southern Poeni Prairie portal, follow the main road towards the ruins.

Head up the stairs, turn right, and use the Blink Talisman to cross the broken bridge. You will spot a chest to the left. Open it and collect the sword blueprint.

Return to a main settlement, such as the Town of Beginnings, and search for the hammer icon on the map to locate the blacksmith. To craft the sword, you will need:
- Hard Bone x 3.
- Magestone x 2.
- Silver Ingot x1.
The Mithril Blade unique mod, Freezing Gift: Time, applies Freeze and decreases sword skills cooldown if nearby enemies are frozen.
