Ypotryll

When making a charge, you can attempt to overrun one creature in the path of the charge as a free action. If you successfully overrun that creature, you can complete the charge. If the overrun is unsuccessful, the charge ends in the space directly in front of that creature.

You gain a +4 bonus on the following checks and saves: Swim checks made to resist nonlethal damage from exhaustion; Constitution checks made to continue running; Constitution checks made to avoid nonlethal damage from a forced march; Constitution checks made to hold your breath; Constitution checks made to avoid nonlethal damage from starvation or thirst; Fortitude saves made to avoid nonlethal damage from hot or cold environments; and Fortitude saves made to resist damage from suffocation.

You may sleep in light or medium armor without becoming fatigued.

You get a +2 bonus on all Fortitude saving throws.

You receive a +2 bonus on checks made to overrun a foe. This bonus stacks with the bonus granted by Improved Overrun. Whenever you overrun opponents, they provoke attacks of opportunity if they are knocked prone by your overrun.

You do not provoke an attack of opportunity when performing a bull rush combat maneuver. In addition, you receive a +2 bonus on checks made to bull rush a foe. You also receive a +2 bonus to your Combat Maneuver Defense whenever an opponent tries to bull rush you.

You do not provoke an attack of opportunity when performing an overrun combat maneuver. In addition, you receive a +2 bonus on checks made to overrun a foe.

The creature's secondary attacks with natural weapons take only a –2 penalty.

You can choose to take a –1 penalty on all melee attack rolls and combat maneuver checks to gain a +2 bonus on all melee damage rolls. This bonus to damage is increased by half (+50%) if you are making an attack with a two-handed weapon, a one handed weapon using two hands, or a primary natural weapon that adds 1-1/2 times your Strength modifier on damage rolls. This bonus to damage is halved (–50%) if you are making an attack with an off-hand weapon or secondary natural weapon. When your base attack bonus reaches +4, and every 4 points thereafter, the penalty increases by –1 and the bonus to damage increases by +2. You must choose to use this feat before making an attack roll, and its effects last until your next turn. The bonus damage does not apply to touch attacks or effects that do not deal hit point damage.

When running, you move five times your normal speed (if wearing medium, light, or no armor and carrying no more than a medium load) or four times your speed (if wearing heavy armor or carrying a heavy load). If you make a jump after a running start (see the Acrobatics skill description), you gain a +4 bonus on your Acrobatics check. While running, you retain your Dexterity bonus to your Armor Class.

You gain +3 hit points. For every Hit Die you possess beyond 3, you gain an additional +1 hit point. If you have more than 3 Hit Dice, you gain +1 hit points whenever you gain a Hit Die (such as when you gain a level).
