The “Lightning Sheath” is an ingenious piece of equipment that can fit any rapier.

This sheath features a special mechanism that, once activated, allows the adventurer to make two attacks when attacking an enemy. The first attack is free and is linked to the spring mechanism, causing the weapon to spring out of the sheath and allowing a free attack as the weapon is drawn, while the second attack is made using the normal action.

However, to reset the mechanism after use, the adventurer must reinsert the weapon into the sheath and lock it. This process takes 30 seconds, requiring careful planning and consideration before being able to benefit from the double attack effect again.
