Crom cultists
Cult Sacrifice: Priests never charge for healing - other cultists save "icons" from their defeated enemies and sacrifice them in a fire.

Cult Ability:The cult of Crom does not teach a special ability

Divine Intervention:Crom does not intervene in mortal affairs. But there is a 1% chance that a sacrified enemy icon, if obtained courageously, may be altered by the god and returned to the cultist as a beneficial magic item

The Temple of Crom in Waterdeep

The Waterdeep Temple of Crom was founded (by Aerin Golgukuri-Cullan, a mage and priestess of Crom) for the purpose of helping those that could not help themselves. To this end, the temple was not located North Ward with the other large temples. Instead, it is located across the way from the home of Mirt the Moneylender (see note 1), just outside of Dock Ward.

One of the features that most sets apart the Temple of Crom from all others is that it doesn't charge money for healing services. Donations are accepted, but no one is turned away due to lack of funds. The only likely charge is that of service. The temple will ask that the petitioner, in gratitude of the healing they've been given, help others as they are able. A common request of lower level adventurers is that they repay the healing by serving a stint in the city watch.

The philosophy of the temple is to help those that cannot help themselves and, if possible, teach them to be able to help themselves in the future.

The tenets of the faith are a strong respect for individuality and self reliance, the idea of might for right - not might makes right, the idea that "That which does not kill us makes us stronger" and the philosophy and implications of the idea "Suffer no guilt." Facing up to your enemies (without or within), fighting valiantly, behaving with honor - these are all revered by the follower of Crom. There is also a basic acknowledgment that life isn't necessarily fair. The followers of Crom are expected to work with life as it comes. A description of this attitude might be summarized by, "Stuff happens. Stop complaining and deal with it."

The holy symbol used by the temple in Waterdeep is a hammer and anvil superimposed over an eclipsed starburst (a black 8-pointed star outlined in silver or on a silver circle). The hammer and anvil signifies the forging of the soul, and the eclipsed starburst is the personal sigil of the founder of the temple. Mages use the same basic symbol, with a pentagram placed on the anvil.

There is no set schedule of sacrifice or tithing. Again, donations are accepted if the person is able, and help might be given if they are not. The sacrifice is generally the icon of a defeated foe. In the case of defeating a powerful enemy in physical battle, the icon would be that person's weapon (or perhaps spellbook if the enemy was a mage). Someone that had fought and won against a debilitating opium addiction would sacrifice the water pipe as a symbol of the addiction's defeat. If the sacrifice is acceptable it is consumed in a golden flame (that burns only the item being sacrificed). Sometimes, if the fight has been particularly valiant, or the foe especially strong, the item is purified by the flames and returned to the person making the sacrifice. An evil sword might be transformed into a weapon for good in the hands of the faithful. Weapons which are so transformed are always gold-colored and inscribed somewhere with the statement "Suffer No Guilt". Sacrifices from a battle that was no challenge, or that might not be considered honorable are always rejected. Crom rarely intervenes or aids followers who are in positions of failure or weakness; after all, He wasn't the one who got you into trouble. But He respects someone who can face a desperate situation and emerge victorious. Even if you die trying, He respects a valiant effort and will welcome you to His hall.

Followers of Crom are expected to act honorably, and to stand up for what they believe is right. Cowardice is the worst accusation you can make against a follower of Crom. Cowardice by the clergy will result in loss of ability until they have redeemed themselves. A strategic retreat from overwhelming odds is not necessarily cowardice - Crom understands the concept of living to fight another day. But leaving behind a wounded companion to save oneself - that is the basest of acts.

The main holy book of the temple is called The Book of Forgings, a collection of essays by respected past members of Crom's clergy. It teaches that, as the follower lives with honor, fights evil, always strives to give their very best, and doesn't turn aside from the difficulties life holds, they are engaged in the forging of their soul. Someone facing a particularly fearsome challenge (such as a foe that has been their life's goal to bring down) are sometimes said to be "writing their chapter" in The Book of Forgings.

There are fairly standard services offered a couple of days during the week. These would be things like singing hymns, hearing stories of previous followers of Crom and lectures from some of the liturgical texts. The main night service is held every 8 days by Aerin. The service begins with a hymn or hymns, but diverges from the usual service from there. Generally she opens with a philosophical question she's been thinking about, gives her thoughts on the subject, asks if anyone else has thoughts on the subject, and sometimes suggests they think about it over the coming week. Then she tells what deeds she's done since the last service that are worthy of Crom's attention. She then asks the congregation, "What have you done this week?" Those that wish to share their deeds, their victories or trials, have their chance to speak. The congregation offers their congratulations or support, sharing in each other's lives. Speaking is always optional, and it's not unusual for someone to be shy about talking so openly when they first arrive. Afterwards she makes a point of talking to those that wish to speak more privately and generally at least saying "hi" to everyone. A group of people, including Aerin, often go out afterwards to one of the fest halls - the Dripping Dagger, the Misty Beard and the Three Pearls are particular favorites.
