Monster

Monsters are a variety of non-sentient beings from Tortus. They have a unique trait of being able to manipulate mana, without the need of any Magic Circle or Incantation, and each one of them has a unique racial Skill, ranging from ranged attacks to faster movement.

Monsters are created naturally when an animal has enough mana absorbed into their body that transforms them. As a result of this process, monsters have cores of crystallised mana in their bodies that can be of great value. They gain powers by eating the flesh of humans and other monsters.

Monsters can be artificially created by someone in possession of Metamorphosis Magic.

Monster meat is extremely poisonous and lethal to anyone human that consumes it, as doing so would destroy persons body from inside on a cellular level and tries to rebuild its structure, which a body won't be able to handle unless its able to rapidly regenerate and heal itself. The only way known to be able to survive after consume monster meat is through consuming Ambrosia, a drink formed of concentrated liquefied mana released from a legendary crystal known as the Divinity Stone when the latter eat the monster meat and drink the liquefied mana and turn into a human/monster hybrid but not considered as humans anymore as a cost for their mutations.

Monsters are normally non-sentient beings and the only way to gain true sentience, is by drinking Ambrosia.

Sea-based monsters are more attuned to sensing sources of mana than other monsters due to using it as a way to navigate while their other senses are dulled underwater.
