Monster spell

A monster spell is a category of spells that only spell-casting monsters can make use of. Some are unique to this category, while others share properties with other magical items.

Monsters can only cast spells if they are not cancelled and at least level one, and can only cast once every (10 - (monster's level)) turns to a minimum of two turns; they will attempt to cast spells if these conditions are not met, producing a "curse" message. Even with these conditions satisfied, there is a 2 in (monster's level) chance of the spell failing (with five times that chance if the monster is confused).

Spells

There are three categories of spells that monsters can cast. These are Ray-type spells, Mage spells, and Clerical spells. No creature is able to cast spells in more than one category. In the tables below, Min. level refers to the minimum level required for the monster to be able to cast that spell. The monsters that use the type of spells in each table are listed in the Monsters column. In this table, we assume that each monster is generated at its highest possible level, and each monster can cast the spell on the line it appears, as well as every spell above it. It is still theoretically possible for monsters to cast spells that appear below their names in the table, if they drink enough potions of gain level.

The spell Double Trouble can only be used by the Wizard of Yendor.

Ray-type spells

Ray-type spells come in three varieties (though only two are in use). They can be cast from afar, and when used this way, act the same as wands or breath weapons. When cast from an adjoining square, they act as melee attacks and cannot be reflected, but the appropriate resistance will still nullify them.

• Three creatures use magic missile, Angels, Yeenoghu and the Oracle (the Oracle's version is passive and will only occur in response to a melee attack). Magic resistance is proof against this attack. The message is, "You are hit by a shower of missiles!" "The missiles bounce off!" if you have magic resistance.
• Asmodeus, and no one else, has a cold attack. "You are covered in frost" when hit by this attack. Cold resistance nullifies it.
• The source code also supports a fire attack. "You are enveloped in flames" when hit by this attack, and fire resistance nullifies it. No monster has this attack.
