If the horse moves at least 20 feet straight towards the target before the attack the target makes a DC 14 Strength saving throw falling prone on a failure. The nightmare can move through the space of a prone creature as long as it does not end its turn there.
• Ethereal Shift (Recharge 5-6). The nightmare and a rider magically pass from the Ethereal Plane to the Material Plane or vice versa.

• Fiery Trail. When the nightmare moves along the ground, it can choose to leave behind a trail of fire 10 feet wide and 10 feet tall, which lasts until the beginning of the nightmares next turn.
