Mental Flaws
Creatures with mental flaws are particularly susceptible to manipulation, fear, or psychological attacks. They may fall victim to illusions, be deceived into dangerous situations, or be controlled through mind-altering powers. These mental weaknesses can make them dangerous to themselves or easy to manipulate.
Many mythical beings, despite their strength, are mentally vulnerable and can be led into traps or confusion. Some creatures can be dominated through mind control or tricked into surrender.
