Generation
Randomly generated spellbooks have a ~3.56% chance of being a spellbook of create monster. Aligned priests have a chance of being generated with one among their set of spellbooks.
Priests may begin the game with a spellbook of create monster as one of their two starting spellbooks, while wizards have a chance to receive this as their starting non-force bolt spellbook.
Effects
The spell of create monster is a clerical spell; when cast, it has a 72/73 chance of creating a single monster or horde, and a 1/73 chance of creating 2-5 miscellaneous monsters, as with an uncursed scroll of create monster. The monsters will almost always have a difficulty level at or below your current level, and a monsters normally generated in groups (such as orcs or ants) will count as a single monster for the purposes of this spell. The monsters may be peaceful with the normal probability, but will never be tame; this is not a "create pet" spell.
Strategy
Create monster is a rather niche utility spell, of little use to most early-to-mid game players. The monsters it creates are the same ones the game is happy to throw at you with no expenditure of resources on your part. If you're near an altar and have energy to spare, you might get some luck or an artifact weapon if the spell happens to generate monsters which leave corpses. The potential gains must be balanced against the risk of summoning something dangerous like a leocrotta or swarm of soldier ants, especially if you've just expended the last of your energy on this very spell.
Players with little food available might be able to use this spell to generate nutrition, either from the monsters' corpses or their death drops, if they can cast the spell reliably (a failed cast still burns 20 nutrition), the monsters created can leave corpses, do leave corpses, and the corpses are safe to eat and are filling enough to be worth it. Non-wizards are unlikely to find the spell nutrition-positive before the depths where starvation ceases to be a threat.
If your Quest generates monsters with useful corpses, this spell might create several of them more quickly than simply waiting for them to be generated.
Like other low-level spells, this one can be used to train skill in clerical spells, in preparation for casting the higher-level spells of remove curse and/or turn undead.
Late-game characters with the Eye of the Aethiopica may use this spell for altar farming.
Extinction
The spell of create monster is the central spell for extinctionist players, as it is by far the most reliable method to create large amounts of monsters for the challenge. Wizards and Priests are not only the most adept casters for the spell by far, but can also farm wraiths with some reliably in order to increase their level and power reserves.
