Demon Takeover

When the spell is cast a demon takes over your body and uses you as its host for five minutes. If your a warlock and your patron is the fiend then that is who takes it over. If your a wizard or sorcerer than the demon is Etrigan, with Etrigan you grow 3 times your size, turn yellow, get horns and purple and red robes. Etrigan is as powerful as Three level 20 barbarians in raw strength. After the spell is finished you can't cast spells again until a short rest because your body is too ravaged.
