Anti-Magic

Overview
Anti-Magic refers to a vast category of magic that has the innate ability to dispel, weaken, or reflect/deflect magical abilities/effects/objects. This can manifest in many ways; A null-magic aura/area, a shield/carapace of anti-magic, runes that reflect/deflect magic (sometimes the runes can also dispel magic), etc.

Anti-Magic can be overpowered, and has sparked some controversy before. Usually there is some sort of tradeoff, as described in the Limitations section.

Note: The reflection/deflection of magic is not inherently Anti-Magic, but it could be a version of it, described below.

Techniques
Null-Magic Aura: With this type of Anti-Magic, any magical affects, objects, or abilities are dispelled upon entering the Null-Magic Aura of a person or object. This effect could be applied to weapons, creatures, objects, etc. This is the most common type of Anti-Magic.

Deflect/Reflect/Absorbing Shield: The user of this shield may have a translucent or transparent armor around/on/in their body that reflects or deflects magic. It could also absorb the power of magic, reflecting it back after harboring it temporarily. This effect could be applied to sensible & compatible objects with proper Runic Magic/Sygaldry. This type of Anti-Magic could be especially dangerous to mages, as it can reflect their power back to them in a seemingly breathless action.

Touch of Anti-Magic: This is a more interesting type of Anti-Magic, as it requires more action. In this category, a body part/the whole body of a user absorbs/dispels magic. For example, one could have an Anti-Magic set of hands that must come in contact with magic to dispel or absorb it.

Limitations
Often, Anti-magic users don't have [other] magical abilities. This could result in them being far over the median power level, because they could crush mage characters with Anti-Magic, and even destroy physical-fighters with magic. Usually, Anti-Magic users are athletic and fit, and may be considered physical fighters.

There are also usually some ways to get around the Anti-Magic capabilities of a character. For example, maybe the character has to see the magical occurrence to interfere with it's magical nature. On top of that, Anti-Magic users could dispel enchantments on weapons/ammunition, but not the weapon itself, meaning they could be caught off guard or confused temporarily.
