Some feats have prerequisites. Your character must have the indicated ability score, class feature, feat, skill, base attack bonus, or other quality designated in order to select or use that feat. A character can gain a feat at the same level at which he or she gains the prerequisite.
A character can’t use a feat if he or she has lost a prerequisite.
Types of Feats
Some feats are general, meaning that no special rules govern them as a group. Others are item creation feats, which allow spellcasters to create magic items of all sorts. A metamagic feat lets a spellcaster prepare and cast a spell with greater effect, albeit as if the spell were a higher spell level than it actually is.
Here is the format for feat descriptions.
Feat Name (Type of Feat)
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 a class level that a character must have in order to acquire this 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.
In general, having a feat twice is the same as having it once.
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 facts about the feat that may be helpful when you decide whether to acquire the feat.
(Epic Feats) (General)
Acquiring Epic Feats
Characters gain epic feats in the following ways:
At 21st level, and every three levels thereafter, the character may select an epic feat in place of anonepic feat.
Each character class gains bonus epic feats according to the class description. These feats must be selected from the list of bonus epic feats for that class.
Most epic feats have prerequisites. A character must have the listed ability score, feat, skill, class feature, or base attack modifier in order to select or use that feat. A character can gain an epic feat at the same level at which he or she gains the prerequisite, just as with regular feats. A prerequisite expressed as a numerical value is a minimum; any value higher than the one given also meets the prerequisite. A character can’t use an epic feat if he or she has lost a prerequisite.
Types Of Epic Feats
Most epic feats are general, meaning that no special rules govern them as a group. Others may be item creation feats or metamagic feats, which follow all the normal rules for such feats, except as specified in the feat’s description. In addition, some feats are defined as divine feats or as wild feats. Such feats are described below.
The feats in this category share a few characteristics. First, they all have as a prerequisite the ability to turn (or, in most cases, rebuke) undead. Thus, they are open to clerics, paladins of 4th level or higher, and any prestige class that has that ability. (An ability to turn other creatures does not qualify a character to select one of these feats.) Second, the force that powers a divine feat is the ability to channel positive or negative energy to turn or rebuke undead. Each use of a divine feat costs the character one turn/rebuke attempt from his or her number of attempts each day. If a character doesn’t have any turn/rebuke attempts left, he or she can’t use the feat. Since turning or rebuking is a standard action, activating any of these feats is also a standard action.
The feats in this category share the characteristic of relating to the ability to use wild shape as a druid. These feats require the character to have the ability to use wild shape before acquiring the feat.
Epic Psionic Feats
Psionic characters can acquire epic ‘psionically flavored’ feats. Some feats require so much translation that converted feats are provided. Whenever a feat concerns conferring or altering a spell in some fashion, some translation must be done to use it with psionics. Sometimes this translation is as straightforward as changing a few names. Translating epic metamagic feats to epic metapsionic feats requires that Spellcraft prerequisites be replaced with Psicraft. It also requires a little mathinstead of casting a spell at a higher level, a psionic character pays more power points. For every spell slot one level higher than the spell’s actual level the metamagic feat requires, the metapsionic feat requires a character to pay a power point cost equal to its standard cost +2. Likewise, when a feat allows a spellcaster to pay one less level to use a metamagic feat, the psionic version allows a character to pay 2 power points less for a given metapsionic feat.
