Ritual Magic

Ritual Magic (儀式魔法, Gishiki Mahō) is a unique form of magic that incorporates the use of rituals into several effects into each spell, each requiring its own ritual, sacrifice and requests. It is considered unique due to the fact it is classed as both a Holder and Caster magic.

Description
The use of Ritual Magic doesn't require much from the user, simply be knowledgeable about magic, have good enough intelligent to be capable of solving "riddles" that hide the method of the ritual needed to cast a certain spell and effect, it is also needed for the user to be ready to sacrifice whatever is needed in order to complete a ritual.

A ritual can vary widly, from incantations, to sacrifices, magic circles and the user of certain tools. Rituals aren't neccesary exclusive to a single form of magic, as such a ritual can cast a spell from any magic that exists, of course it is required for the user to know the magic first, knowing a magic well is what's needed for the user to know what the ritual may require to activate the spell.

Certain spells, can be originally created by the user, if the user has enough experience, patience and education in magic, then the user can infact create rituals that their end result would be an original spell or effect, from sealing to attacking and defending.

While this magic may seem capable of doing anything, it has its drawbacks, for once, a ritual still costs magic power, which depending on the scale and the ritual itself, can cost very little or very much. A ritual can also backfire on the user if anything were to go wrong, even a defensive spell can become harmful to the user, resulting in an explosion or the aim of an offensive spell being too close or right towards the user. As such, a ritual requires no interruptions in order to activate, making the user very vulnerable to attacks when doing a ritual.
