Once every 1d4 rounds, a vavakia can breathe out a 60-foot cone of green fire that seems to writhe and coil with the tortured shapes of a thousand screaming ghosts. This green fire is akin to vomiting up the countless souls the vavakia has consumed, and these souls consume flesh as surely as they consume sanity. A creature struck by this breath weapon takes necrotic damage (Breath save halves)-this damage manifests as blackened, melted flesh and skin but is treated as raw profane power. Evil creatures take half damage from the breath weapon, but good creatures who take any damage from a vavakia's breath weapon are automatically staggered for 1 round by the hideous sensation. In addition, any living creature that takes damage from a vavakia's breath weapon must also make a Death save to avoid suffering 1d8 points of Wisdom damage as her sanity slips away into madness. Immediately after the vavakia expels this green "soul fire", the wailing flames flow in reverse back into the demon's gullet through its open maw. This heals the vavakia effect. Ability damage from this effect can only be healed via restoration or more powerful healing magic.
