Sympathetic Blade

 is a weapon in SINoALICE.

Weapon Story
With one look it was easy to see that this blade had an unrivaled edge. However, the swordsman felt something was amiss, as it was obvious this sword had yet to taste the blood of battle.

The skeptical swordsman asked the hawker about the item. "Has this sword seen battle?" he wondered. The hawker reassured the swordsman it must have, considering the blade had been around since his grandfather's time.

The swordsman carefully examined the sword.

There, he noticed that not only had it a sharp edge, but it also contained a magic catalyst, peerless in design. This dark magic was sealed in the hilt and could amplify the sword's strength by absorbing the wielder's magic power.

"This is indeed quite the item..." murmured the swordsman as he rushed home with his new possession.

However, the hawker had neglected to inform him that each swing required a complex spell. Regardless, the hawker quickly left town after selling his stock of defective wares.
