Most of the following feats apply specifically to monsters, although some player characters might qualify for them (particularly Craft Construct).
Note that for the purposes of this site it was decided that a feat that wasn't explicitly notated as a "monster feat" in the original source materials but which, by it's prerequisites or other requirements, is exceptionally unlikely to be a viable choice for a player character was listed here. Such feats include those with a prerequisite of a type or subtype that are not normally player character options, such as the giant or fire subtypes. If characters can somehow gain these subtypes or otherwise do meet all of the prerequisites please consult with your GM to see if such feats are allowed for PCs in his or her campaign.
If you are building a new monster, note that each creature with an Intelligence score receives a number of feats equal to 1 + 1 per every 2 Hit Dice after the first (so, 1 at 1 HD, 2 at 3 HD, etc.). A creature must qualify to take a feat as normal.
See Table: Statistics Summary for a quick feat calculation chart for determining number of feats a creature should receive.
Monster Feats are summarized on the table below. Note that the prerequisites and benefits of the feats on this table are abbreviated for ease of reference. See the feats description for full details.
The following format is used for all feat descriptions.
Feat Name: The feat's name also indicates what subcategory, if any, the feat belongs to, and is followed by a basic description of what the feat does.
Prerequisite: A minimum ability score, another feat or feats, a minimum base attack bonus, a minimum number of ranks in one or more skills, or anything else required in order to take the feat. This entry is absent if a feat has no prerequisite. A feat may have more than one prerequisite.
Benefit: What the feat enables the character (“you” in the feat description) to do. If a character has the same feat more than once, its benefits do not stack unless indicated otherwise in the description.
Normal: What a character who does not have this feat is limited to or restricted from doing. If not having the feat causes no particular drawback, this entry is absent.
Special: Additional unusual facts about the feat.
