SRD:Special Attacks and Special Qualities (Creature Statistic)
From D&D Wiki
|This material is published under the OGL|
Many creatures have unusual abilities. A monster entry breaks these abilities into special attacks and special qualities. The latter category includes defenses, vulnerabilities, and other special abilities that are not modes of attack. A special ability is either extraordinary (Ex), spell-like (Sp), or supernatural (Su). Additional information (when needed) is provided in the creature’s descriptive text.
When a special ability allows a saving throw, the kind of save and the save DC is noted in the descriptive text. Most saving throws against special abilities have DCs calculated as follows: 10 + 1/2 the attacker’s racial Hit Dice + the relevant ability modifier.
Creatures with Psi-Like Abilities
Powers that have increased effects due to augmentation include information about the effect. An asterisk indicates that the power has already been augmented by the creature’s innate ability.
Powers that can’t be augmented, or that are manifested at their normal minimum level, do not contain any special notations. Resolve the effect of manifesting the power without augmentation at the creature’s given manifester level.
Some creatures may have particular powers that are manifested at a higher or lower level than their normal manifester level. In such cases, the manifester level is given in the parenthetical information following the power name.
