I'm a bit scared.

I was curious and went into an immortal spell in the good luck section. To cast the spell you must think it and I read it and miscasts lead to death. So I'm nervous at the moment. Please help.

Spells like that aren't very credible. Most witches consider immortality spells to be completely fake, so I wouldn't worry about it if I were you.

Spells like immortality, shape-shifting, element bending, etc.. are all fake. The " consequences of failing " them such has death, are also fake. If something can not be done, there's really no action, therefor no consequence.
