Mind spell

Mind spell is a term for a spell that is considered to affect a creature's mind. The following spells are mind spells:

•  Berserk
•  Blind
•  Forgetfulness
•  Frenzy
•  Hypnotize
•  Mirth
•  Sorrow

Some creatures have a specific immunity to mind spells. Psychic Elementals do half damage to these creatures.   In Horn of the Abyss, the artifact Sleepkeeper makes all of the hero's creatures immune to mind spells. Liches and Power Liches are not immune to Forgetfulness in The Shadow of Death, but are immune to it in Horn of the Abyss (can be negated with the help of the Orb of Vulnerability). All undead creatures become vulnerable to Berserk, Frenzy (only friendly creatures except hypnotized), and Hypnotize if a hero equips the Orb of Vulnerability.
