You summon up the strength of the great dragons to change your form, manifesting a tail that thrashes with power. You can use a standard action to attack with a tail slap natural weapon that deals 1d8 points of damage. You can choose to deal nonlethal damage with your tail slap, taking the standard -4 penalty on your attack roll.
If you tail slap as your only attack, you use your highest base attack bonus on the attack roll, and apply 1-1/2 times your Strength bonus on damage rolls. If you tail slap in addition to making other attacks, the tail slap is a secondary attack.
You can augment this power in one or both of the following ways.
- For every 4 additional power points you spend, your tail slap deals an extra 1d8 points of damage.
- If you spend 6 additional power points (not including points spent to increase your tail slap damage), this power grants you a tail sweep attack in addition to a tail slap attack. The tail sweep affects a half-circle with a radius of 20 feet. Creatures of your size or smaller are affected, automatically taking 2d6 points of damage plus 1-1/2 times your Strength bonus. Affected creatures can attempt Reflex saves for half damage. The save DC equals the DC the power would have if it allowed a save.
