Pathfinder Domains (OGL)

Scalykind Domain
Dieties: Dahak, Ydersius
Granted Powers: You are granted dominion over serpentine creatures, and can call upon reptilian powers of scale and venom.
Serpentstrike (Su): As an attack action, you can cause a single creature to suffer the effects of a snake's bite with a melee touch attack. A translucent serpent of greenish-gold force automatically bites any target you hit with this touch attack, inflicting 1d4 P damage + poison (save Fort DC 10 + 1/2 cleric level; frequency 1/round for 6 rounds; effect 1d2 Con; cure 1 save). You can use this ability a number of times per day equal to 3 + your Wisdom modifier
Master of Scale (Su): At 6th level, any summon monster or summon nature's ally spell can be cast to summon dinosaurs, fish, frogs, reptilian animals or snakes as if a spell of the next higher level. A summon monster III could therefore summon 1 celestial or fiendish deinonychus or pteranadon, or 1d3 celestial or fiendish constrictors, crocodiles, electric eels, giant lizards or sharks, or 1d4+1 celestial or fiendish giant frogs or celestial or fiendish octopus, while a summon nature's ally V could summon 1 elasmosaurus, giant octopus, stegosaurus or triceratops, 1d3 ankylosaurus or giant moray eels, or 1d4+1 deinonychus or pteranodons.
Domain Spells: 1st - magic fang, 2nd - barkskin (presenting a scaly appearance), 3rd - greater magic fang, 4th - poison, 5th - animal growth*, 6th - form of the dragon I, 7th - creeping doom (composed of tiny snakes), 8th - form of the dragon III, 9th - shapechange
* Affects ophidian or reptilian creatures only.

[NOTE: I would add this Domain to the list of options that a Druid can learn via Natural Bond, hence the mention of how it would interact with summon nature's ally.]

Void Domain
Deities: Groetus, Old Cults
Granted Powers: You can call upon the forces of the outer void, bearing yourself into the night sky and calling do
wn the horrors that live between the stars. You gain +2 to saves versus mind-affecting effects.
Creature of the Void (Su): As a full round action, you summon a small grotesque mass of writhing darkness from the void between the stars. On your next turn, it flies unerringly to strike a single target within 30 ft., dealing nonlethal damage equal to 1d6 plus +1 hit point for every two Cleric levels you possess, as well as rendering the target shaken for 1 round.
Void-Dancer's Wings (Su): At 8th level, you become immune to suffocation and damage from environmental cold. Additionally, when you cast a prepared Domain spell of fly upon yourself the duration is increased to 10 minutes per Cleric level and when you cast a prepared Domain spell of overland flight upon yourself, the duration is doubled.
Domain Spells: 1st - feather fall, 2nd - levitate, 3rd - fly, 4th - lesser planar binding, 5th - overland flight, 6th - planar binding, 7th - reverse gravity, 8th - greater planar binding, 9th - gate.

[NOTE: Tien Clerics have a different understanding of the Void, and refer to the Granted Powers as Ancestral Rebuke and Cloud-Vaulter's Wings. The squamous horror called up by Creature of the Void instead manifests as a radiant image of a wrathful ancestral humanoid, but the mechanical effects of its 'rebuke' are the same.]

Mind Domain
Deities: Irori (replaces Rune, if used)
Granted Powers: Your understanding of the inner workings of the mind grants you uncanny insights into others, and remarkable self-control. You gain a +2 to Will saves vs. enchantment spells and effects.
Mind Thrust (Su): As a standard action, you can generate a blast of disorienting psychic energy that inflicts 1d6 nonlethal damage + 1 hit point per two cleric levels to a single target within 30 ft. and causes the target to suffer the effects of the Sickened condition for one round. Only sentient creatures are affected by this psychic blast. You can use this ability a number of times per day equal to 3 + your Wisdom modifier.
Tower of Iron Will (Su): At 6th level, you can generate a faintly visible fortress of psychic protection that grants you and all allies within 30 ft. a bonus to their Will saves equal to your Wisdom modifier, and affording those affected another saving throw (including this bonus) versus any mind-affecting effect currently affecting them, such as fear, confusion, rage, etc. You can generate this mental bastion for as many rounds per day as you have Cleric levels, and the rounds do not need to be consecutive. Each round within the protection confers another saving throw to shake off mental charms, compulsions or other unwanted influence.
Domain Spells: 1st - comprehend languages, 2nd - detect thoughts, 3rd - lesser geas, 4th - discern lies, 5th - telepathic bond, 6th - mass suggestion, 7th - demand, 8th - mind blank, 9th - weird.

Creation Domain
Deities: Torag (replaces Artifice or Earth, if used)
Granted Powers: You have developed a powerful connection to the forces of creation itself, allowing you to form objects within your grasp. The duration of any conjuration (creation) spells you cast as a Cleric are treated as if your caster level was +2.
Creation's Craft (Su): As a full-round action you can create an item within your grasp similar to the effects of minor creation, but limited to a single item with a weight in pounds no greater than your Wisdom modifier + 1 lb. per Cleric level. As with minor creation, complex items may require a Craft check to properly form. You can have no more than one such item in existence at a time, and the item disappears at the end of any round in which it leaves your grasp or possession (otherwise, the duration is permanent). The item can be made of vegetable matter (plant, fibers, leaves, etc.), or bone, chitin, hide, fur or cloth. Items of stone or metal cannot be created with this ability, and, regardless of Craft skill, you cannot make a Masterwork item with this ability, nor use any such created material as a spell component. Items crafted cannot be inherently dangerous, including venomous, disease-ridden or caustic nature, although a weapon (such as a longbow or quarterstaff) can be crafted in this manner. If an item created in this manner is damaged or separated, the entire item dissolves at the end of that round, making it unusable for the creation of foodstuffs (as any bite taken from the whole destroys the entire item).
Craftsmaster (Su): At 8th level, you become able to conjure up items of metal or stone with your creation's craft, and the item created can be Masterwork, assuming that your Craft check is successful. You can also create food and water sufficient to satisfy your own requirements (even if you have already used this ability to fashion a weapon or tool), although you still cannot use this ability to create food or water for others, as the material vanishes at the end of any round in which it leaves your person. The weight of items you can create doubles, and you can have multiple objects in existence at one time, so long as the total items created does not exceed weight in pounds equal to twice your cleric level plus Wisdom modifier. Similar to major creation, you cannot create items of cold iron with this ability.
Domain Spells: 1st - mount, 2nd - minor image, 3rd - create food and water, 4th - minor creation, 5th - major creation, 6th - heroes' feast, 7th - permanent image, 8th - greater shadow conjuration, 9th - shades.

 

Pathfinder Domains (non-OGL)

Metal Domain
Deities: Tien (Chinese elemental schema)
Granted Powers: Your spiritual connection to the element of metal allows you to enhance the protective and damaging power of metal armor and weapons, to imbue yourself with the unfailing durability of metal, and to create weapons of metal in times of need.
Always Armed (Su): You can create a metal weapon within your grasp of up to 1 lb per cleric level as a move action. These weapons vanish at the end of the round if they ever leave your possession. When you use weapons that you have created in this manner in combat, you can use your Wisdom modifier in place of Strength or Dexterity modifiers for attacks and damage.
Always Armored (Su): At 8th level, you gain the ability to create metal weapons with Always Armed as a free action, and weapons created are of masterwork quality. You also gain the ability to absorb one suit of metal armor with an armor bonus equal to your permanent Wisdom modifier, gaining the armor bonus of that armor as a natural armor bonus, but suffering none of the other effects of being armored (armor check penalty, weight carried, movement speed reduction, arcane spell failure or maximum dexterity bonus). Absorbing the armor takes one hour, but it can be expelled as a full-round action at any time. No other properties of the armor are in effect while it is absorbed, and any beneficial magical properties or enhancement bonuses are suspended until it is expelled from your body. Once absorbed, a suit of armor effectively does not exist, conferring only the appropriate natural armor bonus, and you can wear another suit of armor without difficulty.
Domain Spells: 1st - magic weapon*, 2nd - heat metal, 3rd - magic vestment*, 4th - rusting grasp, 5th - wall of iron, 6th - blade barrier, 7th - move earth, 8th - repel metal or stone, 9th - iron body.

*To affect weapons with striking surfaces of metal or armor predominantly composed of metal only.

Wood Domain
Deities: Tien (Chinese elemental schema)
Granted Powers: Your spiritual connection to the element of wood allows you to pass through the forested places unhindered, take on the strength of wood and eventually call the forest to your aid. You can move through natural thorns, briars, overgrown areas, and similar terrain at your normal speed and without taking damage or other impairment. Any such terrain that is magically manipulated to impede motion still impedes you.
Wooden Fortitude (Su): As a standard action, you can touch a creature to grant it Hardness 5 for 3 rounds. You can use this ability a number of times per day equal to 3 + your Wisdom modifier.
Wood like Iron (Su): At 8th level, items, weapons and armor of wood that you carry or wear are strengthened by an Ironwood-like effect that causes them to gain the hardness, hit points, armor value and damaging properties of metal armor, items or weapons, but retain the weight and rust-resistant properties of wood. Armor is treated as one size category lighter, and items that would normally be made primarily of metal are one-half the weight of their metal counterparts. These effects cease at the end of any round that the affected item leaves the Clerics person.
Domain Spells: 1st - shillelagh, 2nd - tree shape, 3rd - speak with plants, 4th - command plants, 5th - tree stride, 6th - repel wood, 7th - liveoak, 8th - changestaff, 9th - control plants.
