Name Type Text
Bite Ability The creature attacks with its mouth, dealing piercing, slashing, and bludgeoning damage.
Blindsense Ability Other creatures have blindsense, a lesser ability that lets the creature notice things it cannot see, but without the precision of blindsight. The creature with blindsense usually does not need to make Spot or Listen checks to notice and locate creatures within range of its blindsense ability, provided that it has line of effect to that creature. Any opponent the creature cannot see has total concealment (50% miss chance) against the creature with blindsense, and the blindsensing creature still has the normal miss chance when attacking foes that have concealment. Visibility still affects the movement of a creature with blindsense. A creature with blindsense is still denied its Dexterity bonus to Armor Class against attacks from creatures it cannot see.
Blindsight Ability Some creatures have blindsight, the extraordinary ability to use a nonvisual sense (or a combination of such senses) to operate effectively without vision. Such sense may include sensitivity to vibrations, acute scent, keen hearing, or echolocation. This ability makes invisibility and concealment (even magical darkness) irrelevant to the creature (though it still can't see ethereal creatures and must have line of effect to a creature or object to discern that creature or object). This ability operates out to a range specified in the creature description. The creature usually does not need to make Spot or Listen checks to notice creatures within range of its blindsight ability. Unless noted otherwise, blindsight is continuous, and the creature need do nothing to use it. Some forms of blindsight, however, must be triggered as a free action. If so, this is noted in the creature's description. If a creature must trigger its blindsight ability, the creature gains the benefits of blindsight only during its turn. Blindsight never allows a creature to distinguish color or visual contrast. A creature cannot read with blindsight. Blindsight does not subject a creature to gaze attacks (even though darkvision does). Blinding attacks do not penalize creatures using blindsight. Deafening attacks thwart blindsight if it relies on hearing. Blindsight works underwater but not in a vacuum. Blindsight negates displacement and blur effects.
Breath Weapon Ability A creature attacking with a breath weapon is actually expelling something from its mouth (rather than conjuring it by means of a spell or some other magical effect). Most creatures with breath weapons are limited to a number of uses per day or by a minimum length of time that must pass between uses. Such creatures are usually smart enough to save their breath weapon until they really need it. Using a breath weapon is typically a standard action. No attack roll is necessary. The breath simply fills its stated area. A breath weapon attack usually deals damage and is often based on some type of energy. Breath weapons usually allow a Reflex save for half damage (DC 10 + ½ breathing creature's racial HD + breathing creature's Con modifier; the exact DC is given in the creature's descriptive text). Some breath weapons allow a Fortitude save or a Will save instead of a Reflex save. Breath weapons are supernatural abilities except where noted. A creature is immune to its own breath weapon unless otherwise noted. Creatures unable to breathe can still use breath weapons. (The term is something of a misnomer.)
Bull Rush Action You can make a bull rush as a standard action (an attack) or as part of a charge. When you make a bull rush, you attempt to push an opponent straight back instead of damaging him. You can only bull rush an opponent who is one size category larger than you, the same size, or smaller. Initiating a Bull Rush First, you move into the defender's space. Doing this provokes an attack of opportunity from each opponent that threatens you, including the defender. (If you have the Improved Bull Rush feat, you don't provoke an attack of opportunity from the defender.) Any attack of opportunity made by anyone other than the defender against you during a bull rush has a 25% chance of accidentally targeting the defender instead, and any attack of opportunity by anyone other than you against the defender likewise has a 25% chance of accidentally targeting you. (When someone makes an attack of opportunity, make the attack roll and then roll to see whether the attack went astray.) Second, you and the defender make opposed Strength checks. You each add a +4 bonus for each size category you are larger than Medium or a -4 penalty for each size category you are smaller than Medium. You get a +2 bonus if you are charging. The defender gets a +4 bonus if he has more than two legs or is otherwise exceptionally stable. Bull Rush Results If you beat the defender's Strength check result, you push him back 5 feet. If you wish to move with the defender, you can push him back an additional 5 feet for each 5 points by which your check result is greater than the defender's check result. You can't, however, exceed your normal movement limit. (Note: The defender provokes attacks of opportunity if he is moved. So do you, if you move with him. The two of you do not provoke attacks of opportunity from each other, however.) If you fail to beat the defender's Strength check result, you move 5 feet straight back to where you were before you moved into his space. If that space is occupied, you fall prone in that space.
Burrow Ability A creature with a burrow speed can tunnel through dirt, but not through rock unless the descriptive text says otherwise. Creatures cannot charge or run while burrowing. Most burrowing creatures do not leave behind tunnels other creatures can use (either because the material they tunnel through fills in behind them or because they do not actually dislocate any material when burrowing); see the individual creature descriptions for details.
