Blueprints are consumed when forging a weapon. You will need a total of 6 blueprints and the corresponding materials to fully max a weapon.
Recomended Characters
| Character | Explanation |
|---|---|
Truffle and Filbert | - The Skill Duration bonus granted by Pyrothirst works well with supports like Truffle and Filbert since it extends the duration of her buffs, which makes for more consistent buff uptime. |
Rebecca | - The increase in Skill Duration allows Rebecca's summons to remain on the field for a longer time. While Siren's Kiss is her BiS, this weapon is a viable placeholder if you don't already have it. |
Lynn | - An increase in Skill Duration translates to Skill Efficiency when applied to characters with toggleable skills. This allows Lynn to use her Ultimate and Consonance Weapons more consistently. |
