Death Mantis

At 10th level, whenever she deals damage with a bite attack as part of her mandibles ability, she also inflicts 1 negative level. The save DC to remove each of these negative levels is equal to 20 + the Red Mantis assassin’s Constitution modifier.

Each negative level inflicted in this manner grants the Red Mantis assassin 5 temporary hit points that last for 1 hour.

In addition, her damage reduction increases to DR 10/good while in this form.
