Here you are,magic groups!
What are seekers?:
Seeksers are what rival illusionists,being as they are not capable of seeking the illusionists casted magic,and if they do happen to see it?they are the only ones able to break the illusions.
Seekers are more commonly found amongst dog monsters along with cat monsters,but occur the same in everyone else.
Seekers can cast their own magic to nullify the illusionists,as its easier that way.
What are illusionists?:
Illusionists are gifted magic and spell casters,mainly coming from humans as it had origianated from one.
Most commonly found in humans and humanoid monsters,the rate it will occur is the same for everyone else.
What are corpse monsters?:
Corpse monsters are somewhat what the name means,as they are partially dead.
These occur when a monster got hit with a fatal blow and subsequently fell down,but did not dust.
They got back up and resumed with their life,bearing the injury that killed them(think of Geno,or horror).
What are the devotees?:
The devotees are a group of people hand picked by the gods themself,making them incredibly strong and intelligent.
These often come from illusionists and other gifted magic users,causing some bad situations as those who are made a devotee is never really background checked.(see lavender and thistle becoming devotees due to Azura.)
