Dominions 3: The Awakening/Magic/Summoning

These ritual spells summon creatures to serve the caster. Creatures summoned by the caster might have abilities not available to recruit-able creatures and the most powerful and efficient summons can serve as SC or Thugs.

Summonable Troops
While the number and types of all summonable units are too great to deal with here in it's entirety, there are some notable beasts worth mentioning:

Conjuration

 * Vine Man (Conj-1 N1, Cost 1N gem) 18 hp and poison immunity, otherwise meh. Vine men are notable because they can be summoned in large numbers very cheaply using an Ivy Crown.
 * Wyvern (Conj-2 A2, Cost 6A gems) mostly notable because of flying and poison/shock immunity, making them good for inclusion in airborne raiding parties. Wyverns can be got 3-for-the-price-of-1 when summoned by a Dragonmaster.
 * Fire Drake, Ice Drake (Conj-2 F2/W2, Cost 8 gems) their AoE breath weapons can be quite effective early on vs the right troops. Like the wyvern, they can be summoned much more cheaply by a Dragonmaster.
 * Kraken (Conj-3 W3, Cost 3W gems) 60 hp, 4x tentacle attacks and Darkvision. These guys are just begging to be buffed into something nasty.
 * Wight (Conj-3 D2, Cost 5D gems) 20 hp, Enc-0 and comes with a sheild and Bane Blade. Solid undead insta-thug trooper, if a bit squishy.
 * Vine Ogre (Conj-3 N3, Cost 2N gems) just a bigger version of a Vine Man with 45 hp. As with the latter, they are of primary of interest due to their low summoning cost with an Ivy Crown.
 * Winter Wolf, Spring Hawk, Summer Lion (Conj-4 ?3, Cost 10/20/30 gems) Summoned in groups of 5, the seasonal animals are notable for being Ethereal and for their respective elemental immunities and auras. The hawks can fly as well, making them good PD-raiders and mage-killers. The wolves are arguably quite cheap for what they bring to the field. When used vs the right enemies, these units can be considered as thugs.
 * Shade Beast (Conj-4 D3, Cost 20D gems) Summoned 15 at a time, these are some of the least expensive Ethereal troops. They have the standard undead immunities, can fight underwater, etc.
 * Spirits of the Wood (Conj-4 N3, Cost 8N gems) 5 inexpensive Ethereal stealthy Hama Dryad units with both Awe and Regeneration but very squishy. They are tricky to use on offense, because they lose 40% of their hp per turn outside their home province (Note: they heal hp back during battle).
 * Kithaironic Lion (Conj-4 N3E1, Cost 6N gems) Notable mostly for its high protection, when given the right buffs it starts to become interesting.
 * Naiad Warriors (Conj-5 W3N1, Cost 30W gems) 15 amphibian troopers with Awe(3).
 * Fire Snakes (Conj-6 F2, Cost 8F gems) 4 fairly squishy animal units armed with a magical attack, making them potential counters vs ethereal units.
 * Sea Troll and Troll (Conj-6 W3/E3, Cost 1W/E gem) Decent (45+) hp and Regeneration for a bargain gem cost. Trolls have lots of uses as meat-shields and bodyguards. The sea variety is amphibian. The problem with Trolls is that they actually require fairly expensive gold upkeep per turn, somewhat unusual in a non-commander. But with the right buffs they earn their keep.
 * Ether Warrior (Conj-6 S4D1, Cost 90S gems) quite expensive gem cost for 15 warriors. The greatest thing of note is they are Ethereal and each bears a magical Moon Blade, making them good counters vs other ethereal magical units.
 * Lamia (Conj-6 N3, Cost 4N gems) these aren't all that great fighters, but in female form they have life-stealing, while in serpent form they have 22 hp and 50% regeneration. As bodyguards to draw attention away from their charge, they might be tough to take down by normal troops.
 * Ghost (Conj-6 D2, Cost 9D gems) Ethereal, cold aura, life-drain and undead. The main problem with these guys is they are quite expensive unless summoned by a very powerful Death mage.
 * Asp Turtle (Conj-7 W3, Cost 15W gems) while it represents a tough monster, at this point in the game most opponents will have the means to deal smartly with tramplers. Being aquatic tends to limit it's usefulness.
 * Catoblepas (Conj-7 W3D2, Cost 15W gems) definitely should be considered for a possible thug/SC chassis when given the right buffs.
 * Eater of the Dead (Conj-8 S4D4, Cost 50S gems) 180hp, 10% Regeneration, cold- and poison-immune, Recuperation, tramples and steals strength. One thing to know about the EotD is that if it "breaks free" then it can be re-summoned again, even by another player.
 * Abomination (Conj-9 S5W2, Cost 25S gems) 266hp, Regeneration, 3x tentacle attacks and a Death Gaze special. ^^
 * Tarrasque (Conj-9 N6, Cost 25N gems) a bit under-powered for being so far up the tech tree, still once you can summon it, it is one of Nature's tougher monsters.

Alteration

 * Manifest Vitriole (Alt-6 W2F1, Cost 2W gems) a big Ethereal lion with a corrosive breath attack. Kewl.
 * Iron Pigs (Alt-6 E3N1, 10E gems) summons 7 size-3Animals with Protection(20) that use a trample attack.

Construction

 * Corpse Man (Const-2 A1D1, Cost 1A gem) A shock-immune undead trooper. Use a Lightning Rod or Staff of Storms to recruit more per cast.
 * Manikin (Const-3 N1D1, Cost 10N gems) Summons 10 undead with a Sleep Vine (fatigue) attack.
 * Clockwork Horrors (Const-5 E2, Cost 12E gems) Summons 12 lifeless heavily armored constructs with full elemental immunities that never rout. The downside is that unlike other magical constructs, they suffer from Exhaustion(15).
 * Crusher (Const-5 E3, Cost 15E gems) 110hp, size-6 lifeless and mindless meatshield with Protection(24) but low att/def skills. They are susceptible to cold/fire/shock and being swarmed by smaller enemies, and they never heal, which tends to give them a very brief shelf-life.
 * Lumber Construct (Const-5 N3, Cost 5N gems) At 70hp it is a somewhat smaller but much cheaper version of a Crusher.
 * Mandragora (Const-5 N2D1, Cost 10N gems) a tougher version of an undead Manikin with 2x Sleep Vine attacks and twice the hp. More powerful N mages will summon more of them per casting.
 * Mechanical Men (Const-7 E2, Cost 15E gems) 10 heavily-armored tireless mindless amphibian troopers with full fire/cold/shock/poison immunities.
 * Siege Golem (Const-9 E3, Cost 20E gems) It's everything you wanted the Crusher to be: full fire/cold/shock/poison immunity, 2x hammer attacks, Siege(100) and it heals after battle. A good candidate for GoR to make a proper SC.
 * Iron Dragon (Const-9 E4, Cost 25E gems) 150hp, fire/cold/shock/poison immunity, Prot(24), size-6 tireless mindless flying trampler. Buff it up, then let slip the dogs of war.
 * Poison Golem (Const-9 D4E2, Cost 35D gems) a toned-down version of a Siege Golem having only fire/poison immunity and 1 fist attack. Instead it possesses a Banefire shield. Another good candidate for GoR.

Enchantment

 * Reanimation (Ench-1 D1, Cost 5D gems) 10 mediocre and fairly fragile undead troops, but they do have cold/poison immunity and they never rout. Most effective when used in large numbers or as chaff to assist larger thugs.
 * Clay Men (Ench-4 W1E1, Cost 5W gems) 5+ regenerating amphibious tireless mindless troopers with poison-immunity. Powerful W mages can summon more per cast.
 * Behemoth (Ench-4 D3, Cost 10D gems) An undead size-6 trampler with 105hp and a Fear(5) aura.
 * Pale Riders (Ench-5 D3, Cost 10D gems) A group of undead knights with the lance's first-strike bonus.
 * Watcher (Ench-5 A3E1, Cost 5A gems) A lightning-shooting statue with 75hp, a Patrol Bonus(50) and Darkvision. Although immobile on the battlefield, they can be moved between provinces when assigned to a commander.
 * Gargoyle (Ench-5 E3A1, Cost 10E gems) 80hp poison-immune, lifeless, mindless, tireless, flying thug. It never heals.
 * Living Statue (Ench-6 E3, Cost 20E gems) 15+ poison-immune, lifeless, mindless, tireless troopers that never heal.
 * Skeleton Archers (Ench-6 D2F1, Cost 5D gems) 10 undead skeleton archers armed with AoE Banefire Bows. ^^
 * Ziz (Ench-6 D3A1, Cost 10D gems) a size-6 flying undead bird with 85hp and a Fear(5) aura.
 * Leviathan (Ench-7 D3W1, Cost 15D gems) another size-6 undead trampler with 143hp and a Fear(10) aura.
 * Carrion Reanimation (Ench-7 D3, Cost 10D gems) 100 undead Soulless, dependent on the availability of fresh corpses.
 * Army of the Dead (Ench-9 D5, Cost 10D gems) 40 undead Longdead troopers.

Blood

 * Spine Devil (Blood-1 B2, Cost 3B slaves) A decent early-game tough demon trooper with 2 attacks and poison barbs.
 * Bone Fiend (Blood-1 B1D1, Cost 3B slaves) 3 undead with 2 attacks, but no armor. For those who can't raise normal skellies maybe.
 * Fiend of Darkness (Blood-2 B2, Cost 5B slaves) Another decent early-game tough demon trooper with 2 attacks, stealthy and flying.
 * Crossbreeding (Blood-3 B1N1, Cost 15B slaves) Note that both Luck and Misfortune affect the chances for powerful beings.
 * Frost Fiend (Blood-3 B2W2, Cost 6B slaves) A flying cold-immune demon with 25hp and a Cold aura.
 * Devil (Blood-3 B2F2, Cost 7B slaves) A flying fire-immune demon with 35hp and a Heat aura.
 * Serpent Fiend (Blood-4 B1, Cost 5B slaves) A poison-immune flying demon.
 * Storm Demon (Blood-4 B2A2, Cost 7B slaves) Ethereal shock- and poison-immune flying demon.
 * Demon Knight (Blood-4 B2E2, Cost 5B slaves) A fire-immune mounted demon with a Fear(5) aura.
 * Dark Vines (Blood-5 B1N3, Cost 12B slaves) They have 126hp, poison immunity and 3 attacks, but are very slow.
 * Ritual of 5 Gates (Blood-6 B5, Cost 28B slaves) Summons 5 demon troopers (1 of each type) for the cost of 1 spell.
 * Blood Rite (Blood-7 B2D2, Cost 33B slaves) Summons 8+ life-stealing immortal Vampire troopers.
 * Improved Crossbreeding (Blood-8 B2N2, Cost 20B slaves) Same as Crossbreeding spell, just more of them.
 * Forces of Darkness (Blood-9 B7, Cost 50B slaves) Mass summoning of Fiends of Darkness.
 * Infernal Forces (Blood-9 B5F2, Cost 50B slaves) Mass summoning of Devils and Imps.
 * Infernal Tempest (Blood-9 B5A2, Cost 50B slaves) Mass summoning of Storm Demons.
 * Forces of Ice (Blood-9 B5W2, Cost 50B slaves) Mass summoning of Frost Fiends.
 * Infernal Crusade (Blood-9 B5E2, Cost 50B slaves) Mass summoning of Demon Knights.

Commanders
These are all pathless Commanders. See next section for summon-able magi.
 * Black Servant (Conj-1 D2, Cost 5D gems) Expensive in gems but it is available very early. Ethereal, Enc-0, cold and poison immune, stealthy and life-stealing. Downside is Prot-0 and subject to banishment from priests, who are also available early.
 * Bane (Conj-3 D2, Cost 8D gems) 23 hp, Enc-0 and comes with a 2-handed Bane Blade and cold aura. Solid undead thug-able commander, if a bit squishy.
 * Bane Lord (Conj-5 D4, Cost 12D gems) 42 hp, Enc-0 and comes with a 2-handed Bane Blade. A tougher size-3 version of a Bane.
 * Revive King (Ench-2 D1, Cost 3D gems) Probably the quickest/cheapest way to get an undead prophet for free corpse reanimation, but it never heals.
 * Horde from Hell (Blood-5 B4, Cost 44B slaves) 25 Imps led by a Devil. The Devil has the same stats as the unit from the spell of that name, but is a Commander as well. Don't ask.
 * Succubus (Blood-5 B4, Cost 66B slaves) A flying stealthy demon assassin that occasionally can seduce an enemy commander.
