Improved Grab (Ex): To use this ability, the hannya must hit with both claw attacks. If it gets a hold, it can constrict.

Constrict (Ex): A hannya deals 1d4 points of damage with a successful grapple check against Medium-size or smaller creatures. While constricting, the hannya can use its claws and bite to attack only the constricted opponent.

Suggestion (Sp): A hannya can project a suggestion into the mind of an unwary character up to 100 feet distant. This is a mind-affecting ability, but is not language-dependent. It otherwise functions as the spell cast by an 8th-level sorcerer (DC 14). A hannya can use this ability as often as she desires, but it does not function on a creature that knows the hannya's true nature or views her as a threat.

Other Spell-like Abilities: At will - polymorph self, detect thoughts. These abilities are as the spells cast by an 8th-level sorcerer (the save DC for detect thoughts is 13).

Aversion to Violets: A hannya does not voluntarily enter a home or any other building surrounded by beds of violets, nor does she attack a character carrying a bouquet of violets, either physically or with spells. In fact, a character carrying violets is immune to the detect thoughts and suggestion abilities of a hannya. In such a case, polymorphed into the form of an old woman, she sweetly asks her intended victim to put the flowers in a vase where she can admire them, or claim that she is allergic to violets and ask the victim to put them away.

A hannya is a devious, cruel fighter, preying almost exclusively on the weak and helpless. When confronted by an opponent that might be a match for her, she withdraws at the earliest opportunity. When a hannya detects the presence of a suitable victim, such as a traveling priest or a lost child, her typical strategy is to assume the form of an old woman with a kind face and pleasing manner, then plant a suggestion in her victim's mind that a lonely old lady needs help or desires company, or can provide the victim with shelter or food. If the victim is drawn to her, the hannya engages in pleasant conversation until she victim trusts her, then attacks.
