Double-Edged Lightning is a weapon swap build for Phantom Blade Zero: Armybreaker and Sanguine Twin as main weapons, Iron Gauntlets and Flying Dagger as Phantom Edges, and Miraculous Scabbard and Executioner’s Headscarf as key accessories. It exploits weapon switching: every switch restores all your Sha-Chi, the Armybreaker charges in when it comes out and the Miraculous Scabbard gives you super armor and less damage taken when you switch.

Armybreaker (Cavalrybane), Sanguine Twin (rack next to the First Meeting with Yu’er bell), Iron Gauntlets, Flying Dagger, at least the Miraculous Scabbard and Executioner’s Headscarf accessories, and the Lament Draught and Simmering Brew medicines. The “How to get all the gear” table shows where each piece is.
From when can I use Double-Edged Lightning?
From the Encampment, Meigu, Imprisonment and Estate stage, which is when you have the weapons, the Phantom Edges and the two key accessories.
Are the damage figures official?
The accessory percentages are the ones published by Vandal (Spanish guide) and SoloJugadores. The game does not show the weapons’ base damage, so the build is based on their effects.
