Incursus

Name: Incursus
Class: Item Creation
Tier: VII
Type: Item
Range: Short
Description:
Link
An simple yet exceptionally crafted blade. Made from forged black iron and Hueco Acero this weapon was made as a simple katana, but with every aspect being worked on in exceptional detail to achieve perfection. The weapon was smithed by folding together both materials continuously, using black iron forging to imbue the weapon’s soul with the concept “Sharpness”. The tsuba(guard) and kashira(end cap) are made of Eleanor Lockwood’s oricalcum. The tsuka(handle) is made from hollowfied ironwood and wrapped Jigokucho silk. The nakago(tang) is inscribed in Retineo with Seran’s maker’s mark as well as the inscription:

I am sharp as guilt
which I use to cut all things
as Seran wills it.

Name: Infinite Sharpness I : Light Cut
Class: Item Creation
Tier: I
Type: Passive
Range: Self
Description: As the ancient Japanese proverb goes: Blades of legendary sharpness were so perfectly crafted that their edges cut through light, rendering the user invisible. Incursus gives testament to this idea, rendering its user invisible when the blade is held in Seigan no Kamae (held directly in front of the user with the edge facing the opponent) or similar. This invisibility is not perfect, and only makes the user invisible while the edge is directly facing the target. This effect also also occurs when the blade is swung, making it, as well as the arms and parts of the body of the user, invisible during the sections of the swing where the edge faces the enemy.

Name: Infinite Sharpness II : Friction Cut
Class: Item Creation
Tier: I
Type: Passive
Range: Self
Description: Along with its remarkable edge, Incursus is also polished to a near mirror shine. But this polish isn’t simply for show, were you to look at the blade with a microscope you would see a completely untarnished surface. This aspect of the blade gives it near a near frictionless surface, making it cut through the air with zero resistance. In base terms, this adds an advantage to any speed based motion the blade takes.

Name: Infinite Sharpness III : Uncuttable Cut
Class: Item Creation
Tier: I
Type: Passive
Range: Self
Description: Taking the legends a step further. During its forging process, Incursus was imbued with the concept of cutting beyond the physical cutting potential of normal weapons. This allows the weapon to cut that which would normally not be impossible. Things such as (but not limited to) fire, wind, lightning, even water will be split cleanly by the blade; leaving a severed void for several posts after it is cut.

Name: Infinite Sharpness IV : Concept Cut
Class: Item Creation
Tier: I
Type: Passive
Range: Self
Description: The final, and likely the most defining form of Incursus’ sharpness. The weapon is so amazingly sharp, and the idea of sharpness forged into the blade so purely, that this weapon is capable of cutting that which has no physical form or appearance. The applications of this aspect of the blade are essentially limitless, but here is an example of its uses on a solid block of steel. Upon cutting the steel the user cuts the concept of “hard”, causing the steel to become soft and malleable like clay. Or he cuts the concept of “steel”, severing the block into the iron and carbon that created it. He could also cut “Solid” causing the steel to melt into a liquid, and then proceed to cut “liquid” to turn it into a gaseous state. Alternatively he could slice the steel’s “weight” causing the metal to become light as a feather, or perhaps even chop through the material’s “potential” causing items created from the steel be poor no matter the skill of the maker. And that is only a taste of what can be accomplished with this ability. It should be noted with concept cut that the user can choose whether or not the blade damages that which is being cut, meaning if the ability was used on an ally the blade would cut into them but only cut the desired concept, leaving the flesh untouched. There are stipulations however:

SPOILER: Click to show

{Spoiler}
-Only one concept can be cut per strike.
-The blade cannot break down into parts things that lack them. So while steel can potentially be broken down into iron and carbon, the remaining elements cannot be split further as they are “pure”.
-The blade cannot cut through concepts that would instantly kill an opponent, such as: “Life”, “existence”, or even something like “heartbeat”.
-The blade cannot cut concepts that would heal a target.
-Cutting concepts that affect a target’s mind such as “identity” or certain emotions like “anger” or “joy” or similar require OOC consent. However these concepts can be severed as part of a technique, for example if a technique caused a being to become angry which caused them to become stronger, cutting “anger” would stop the technique from functioning while leaving the emotion.
-Concepts like race cannot be cut without special permission from mods. For example a vizard cannot be cut into a shinigami and hollow.
-A being’s “skill” cannot be cut to lower masteries, however their “strength” or “speed” can be, which causes it to be halved.
IMPORTANT NOTE: Because of the complexity of this item, most notably the fourth tech, it would be impossible for me to know and write out every single stipulation and a lot of stuff will need to be worked out in objections as the item is used in threads.
IMPORTANT NOTE: With Concept Cut, the outcome of the ability is not entirely within the user’s control, and will often come down to both the user and the opponent’s imagination. This also means that any cut can potentially be a double edged sword. Using the same steel example as above: If an opponent had the ability to control a piece of steel and the user were to cut “solid” to convert the steel to liquid, the opponent would still have control over the material and would now have access to liquid steel. Taking it a step further, the opponent might consider “liquid” steel to be molten, so once the steel was converted to liquid it would also be exceptionally hot, thus increasing the damage it could do, effectively turning Incursus’ power back on the user.
IMPORTANT NOTE: Incursus still works off of advantages and anything of a higher tier after advantages are calculated cannot have its concepts cut by the blade.
