Path Mastery Feats:
Some Shadowcasters are content with the power a path grants them, but others seek greater mastery over a path. Path Mastery Feats each require a complete path to function, along with the Path Mastery feat as a prerequisite. Unless otherwise noted, all Path Mastery Feats are supernatural abilities. Mysteries marked with (HB) are homebrew mysteries from here.

Shadowcraft Feats:
Users of shadow magic have their entire body flooded by the energies of shadow, even when not casting mysteries. Shadowcraft Feats are feats that allow you to create magic items, using your body as the medium for creation. A Shadowcraft item costs no gold to create, but still take the normal amount of time. Instead, your body pays the price, reducing your maximum hit points a certain amount for each item you have crafted. At any point, you may possess a number of shadowcraft items up to your constitution score, although certain shadowcraft items may have additional limitations. You may not willingly destroy a shadowcraft item to make room for a new one unless you possess the Unravel Shadowcraft feat. 
Furthermore, no physical technique will destroy a shadowcraft item. A shadowcraft item is supernatural in nature and can thus not be dispelled, although it is suppressed in the area of a antimagic zone. If a shadowcraft item effect is naturally ended (such as if it imitates a scroll or potion), the price you paid in maximum hit points is restored (although your current hit points are not effected).
Shadowcasters may select Shadowcraft feats as their bonus feats. Shadowcraft items take up no item slot.

Shadow Essence Feats: 
Shadow Essence feats represent a tangible connection to shadows. Each feat taken increases this connection further. However, you lose the benefit while in bright light . Furthermore, if you possess so much as a single shadow essence feat, you are treated as an undead for the purposes of effects with the light descriptor.

Dark Store Feats:
Almost all individuals who have ever heard of shadow magic, including most shadow magic users, assume that all shadow magic hails from the plane of shadow. However, there are rumors of infinitely vast stores of shadow magic, completely separate from the plane of shadows. Some shadow magic users have managed to tap into these stores by using some of their own strength, much as a mosquito taps into a vein. This connection is called upon to create lesser displays of shadow magic, but it may be called upon without limit.
In game terms, whenever the possessor of this feat restores their mysteries, they may opt to gain the benefits of a dark store feats by giving up the use of a mystery of the indicated level for 24 hours. An individual can gain the benefits of multiple dark store feats by giving up the use of multiple mysteries. You may still cast a mystery you surrender if you have more than 1 use of it, or if you have bonus mysteries per day of that level from a high Charisma. Any ability granted by a dark store feat is considered to be a supernatural ability. If the effect of a dark store feat allows a saving throw, its DC equals 10 + level of mystery given up + Charisma modifier. Some dark store feats allow you to surrender higher level mysteries for additional benefit, in which case you need only surrender one mystery of the level you choose and not any other mysteries.
