A shadow priest can get his own shadow, which he calls a shadow. 

The shadow priest uses a spell called shadow power, which allows him to absorb shadow powers from a foe and then channel them into a spell that drains the foe of their shadow powers. 

Shadow priests use shadow power to gain advantages over enemies.

The shadow priest has a special talent that lets him gain a new power at the end of a round.

He also gains a number of shadow points equal to his shadow power score (d6s).

These points are added to his Shadow Pool. 

When he uses a shadow power on a foe, the shadow priest takes the Shadow Power Die (SPD) as a bonus feat.

If he takes the feat in the first round of combat, he takes half the feat’s normal bonus and takes no damage.

He may choose to use the feat before the end, during the round, or after the round ends. 

He can use shadow powers for 1 round per shadow point gained (maximum 10 rounds). 

He gains the shadow power’s effects while in shadow, and may take any action, save or dodge as normal while in shadows. 

If the shadow cleric spends his first shadow point, he loses 1d6 shadow points, but he may reroll a single shadow die to take another shadow point. 

In addition, shadow clerics may choose a single power to spend a shadow point on each round that he has no shadow points. 

A shadow cleric cannot gain more than one power per round. 

Once per round, the Shadow Priest gains one shadow point equal to 1/2 his cleric level. 

For each additional shadow point he gains, he can gain a bonus power equal to the shadow points he has not yet used up.

The maximum number of shadows a shadow cleric can gain is determined by the shadow pool.

A shadow cleric must have at least 1 shadow point to use any ability, and cannot gain any more than 1 shadow points per round for any given round.
