* 【*Appraisal*】
	+ It has an *Appraisal* to be able to see the value of an item or object and material even the information. It's a standard item in games. It is usually sold in the latter half of the RPG, but it is famous as an item that is used only in the early stages. The appraisal skill clearly showed the effect of the item. By the way, one item with a rarity of [★] is a low-value item that can be normally collected around that area. This is not the worst, and there are items below it.
		1. For example, weeds that have no medicinal effect are [rare: none] and cannot even be identified. Even for such items, if you process them properly, the rank will go up.
		2. For example, the same [rare: none] well water as weeds, but if properly processed, it becomes distilled water.

* 【*Item Create*】
	+ The user can create or combine existing material to create inanimate objects/items, such as weapons and platforms, either from nothing, by using existing matter or energy, or through other immaterial sources. In addition, the ability UP item created by Item Create greatly exceeds the ability of the average human being.
	+ This object or weapon that is created will be categorized by the class and rare **[**Rare: ★ → ★x10**]** of the materials that have been used to combine or created from the magic, and every item or object created by the user given an effect depends on the material has been used.
		- For Example: [The materials are Platinum Ingot + Iron Ingot + Magic Stone.] = *Platinum Iron Magic Sword* [Sword] Rare: ★ (It has a magnetic force by alloying platinum and iron. The magnetic force and strength increase by putting in magical power.)
	+ Requirements to create an Item:
		- You need to learn the recipe to create an item.
		- Some items cannot be made if the alchemy (Item Create) level is low.
		- It Consume MP. It can depend on the item that was created, if the item material has a rare material it needs more MP.
* 《*Item Picture Book*》
	+ A collective book or set of all knowledge of the world gives information on many subjects or on many aspects of one subject (plants, animals, monsters, and Items) in which the content is conveyed through the use of words and pictures in combination or through pictures alone, and it's defined by the rarity and even treasured item.
	+ An Item picture book [*Magic Tool*] differs from an illustrated book of all in the world, in that the pictures it contains form an essential part of the structure of the book.
	+ **Effect**: 【*Status Permanently Rising Item*】
		- A permanent stat increase item that is collected and absorbed is an item that increases stats without a time limit. It's basically treated as a rare item, but I promise that it can't be sold at a high price.
