The Slayer's Sword:

This ornate steel blade is linked through the mind, body, and spirit, to the persona of Avun Shidino. Its blade's steel is separated exactly in the middle by a strip of an unknown black metal. It possesses a pattern, made with a mixture of this metal and the steel of the sword itself, that enhances Avun's speed and strength as well as cognition. While the weapon gives him a firm grip over the racial qualities he now possesses, it also chips away at his stamina during battle, making it a double edged blade.

Extreme Cutting Power: The blade's edge has been tempered to perfection using many forbidden techniques long forgotten by humanity. When Avun handles this sword, it will cut through any physical object or creature regardless of their strength or resistance. Stamina will be drawn from Avun to add on to blade's cutting power, requiring larger portions to cut stronger objects. The sword will never kill Avun regardless of his current stamina; at most, its cutting power will be reduced to that of a common steel blade, though its resistance will remain stalwart.

Comfortable Grip: The sword's handle has been forged and crafted many times to ensure the maximum comfort. Avun's strain is greatly reduced through the hilt's magical properties, and he will not tire out as quickly as when handling a normal blade in - or outside of - battle.

Symbiosis: Avun and the blade share an intrinsic link. The sword and its sheath can latch and unlatch to any part of Avun's body, even being able to -be- part of it. Through this symbiosis, Avun can merge the sword with any part of his body for use in stealth or full-blown offense. When Avun becomes one with the blade through fusing it with his arms, these will transfigure into identical blades with the capacity to cut through anything without chipping away at his stamina for a short period of time.

Increased speed: Avun's speed will be increased to the point where common human beings cannot keep up with it. He will be perceived as a blur most of the times, and sometimes not even perceived at all.

Increased strength: Avun's strength will be increased to many times the normal human's physical power. In addition, he will gain increased flexibility as his muscles become stronger in order to keep his body from strain.

Increased cognition: Avun's intellect, observation powers, and mental processing speed are increased to match his newly acquired speed. When he is not moving, Avun's eyes will notice up to the most minute details in the environment around him as well as detect minor heat signatures and sounds around him.

Combat Disease: Every time Avun cuts something with his weapon, the sword will calculate his total and current stamina, his normal strength, and the possibility of the weapon cutting the target without any added force, tiring him out based on these variables. If Avun could slice through the target without the weapon adding any amount of power, then he will suffer no change to his stamina. On the other hand, if the blade has to add on to its own cutting power, the stamina needed to convert to power will be calculated, discounting the total from the handle's imbued abilities.
