Warding Magic

Overview
Warding Magic is a type of Runic magic that is very defensive and more dangerous. Wards are runes used to repel attackers and defend estates or people. You could put a genetically-sensitive ward on a sword-hilt to where it lets off intense heat when it senses other genetic signatures other than your own.

Runic magic can take time if you're an artificer, making magical artifacts. Warding is quicker, and sometimes instant. It can be used to combine and stack magical effects to no ends to defend, safeguard, and repulse.

Capabilities
There are an unlimited amount of wards and an even further unlimited amount of combinations for said wards. Wards can be used in many ways, often to defend places. Maybe the wards don't allow demon-like entities into the premises, or maybe they receive a high degree of blood-pressure upon stepping the boundary. Truly powerful wards take time and effort to craft and meld with objects or people. You could alter yourself with wards, making invisible shields and such. Warding Magic requires creativity and effort to pull off effectively.

Limitations
Wards can be exhausting to craft for some, and require pools of mana. Wards also often display themselves in physical forms, making them hard to disguise. They can often be riddled with holes, and so much as a single mistake could destroy days of work and effort.
