Giant Frilled Lizard

Intimidating Charge. When a giant frilled lizard charges, it hisses ferociously, extends its neck frills, and darts forward on its hind legs, increasing its walking speed to 50 feet for that round. In addition, the creature charged must succeed on a DC 13 Charisma saving throw or be frightened for 1d6 rounds. The creature can repeat the save at the end of each of its turns, ending the effect on a success.
