Though a lamia appears to have an array of powerful natural weapons, its legs and claws (or hooves) are not very strong. Lamias wield daggers in combat when not using their Wisdom drain.
Lamias make excellent use of their magical abilities when hunting. They set illusions to lure would-be heroes into perilous situations, then attack from behind.
Spell-Like Abilities: 1/day - charm person, major image, mirror image, and suggestion. These abilities are as the spells cast by a 9th-level sorcerer (save DC 11 + spell level).
Wisdom Drain (Su): By making a successful touch attack, a lamia permanently drains 1 point of Wisdom. Lamias try to use this power early in an encounter to make foes more susceptible to charm person and suggestion.
