Magic Amulet

A Magic Amulet (魔法のお守り, Mahō no omamori) is a Magic Item and a form of Holder Magic. Similar to Magic Staves it’s used as a medium from which to channel the ambient eternano saturated within the environment, based off the thought patterns of the artifact’s wielder.

Description
The Magic Amulet was created by a wizard known as Isnostre as a counterpart to Magic Staves. Unlike the staff the amulet naturally synchronizes with the mages brain so doesn’t need to be regularly recalibrated to ensure optimal performance. It is believed that it led to the discovery of magic being less a force that magicians can channel with the help of their weaponry as a "terminal" and more a unique particle that can be utilized through a special organ in the magician's body.

It can turn any thought made with sufficient concentration into reality. Anything the wielder can imagine comes true with a minimum of effort. This can make them more than a match for experienced mages, since they don’t have to learn spells, gestures, formulas, or any other magic casting rituals.

The flip side of this huge advantage is that an amulet that works on imagination doesn’t make up for experience that allows one to understand and outthink one’s foe. The wielder still has to learn how to stabilize their energies to prevent risk of backlash as well as know the upper limit of absorption of their Magic Origin. A Magic Staff serves as a "computer" that can take over tasks that the human brain cannot handle efficiently enough. A Magic Amulet merely acts as a conduit.
