Heroes of Battle
Luna moths are not great fighters, relying on their natural invisibility and sleep dust to avoid predators and to stalk prey. When forced to fight, luna moths will slam prey with their wings and try to use their sleep dust to neutralize multiple threats.
Natural Invisibility (Su): A luna moth is invisible except while in direct moonlight. This ability is constant, allowing a luna moth to remain invisible even when attacking. This ability is inherent and not subject to the invisibility purge spell.
See Invisible (Su): A luna moth can see any invisible or ethereal objects or beings within its range of vision, as if they were normally visible.
Sleep Dust (Su): Once per day, a luna moth can release sleep-inducing dust from the underside of its wings, filling a 20-foot-radius spread. This dust causes a magical slumber to come upon 4 Hit Dice worth of creatures within the area (Will DC 14 negates). Its effect is otherwise identical to the sleep spell. The save DC is Charisma-based.
Skills: luna moths have a +4 racial bonus on Move Silently and Spot checks.
Luna moths gain a +4 racial bonus on Hide checks in moonlight. (They are naturally invisible under all other light conditions.)
