Also, the geyser spell will cause the player's inventory to become [[wet]], and on a [[lethe]] level possibly disenchant items or transform them into potions or scrolls of amnesia. There are also the following new arcane spells, which can be cast by monsters of level 9 or higher unless otherwise noted:
 
−
*[[Damage armor]], which works like destroy armor but only damages a worn armor item by one stage (can destroy the item if it was thoroughly eroded already), and fooproof armor items resist;
 
−
*[[Wither]], which works like damage armor but also damages and eventually destroys fooproof items as well as those outright immune to damage (dragon scale mail for example);
 
−

−
*[[Levitate]], requires the monster to be at least level 13; this spell causes the player to float in the air for a period of time, preventing them from picking up items;
 
−
*[[Summon Ghost]], requires the monster to be at least level 19; the player is surrounded by stronger versions of regular [[player monster]]s. If there are entries in the high-score file, the names and classes of these monsters are directly taken from there; the first 1000 entries in the list are eligible for selection. If no entries exist, random player monsters with random names (taken from a preset list) are created instead.
 
−
*[[Enrage]], requires the monster to be at least level 22; this spell heals all hostile monsters in a certain radius around the player, causes peaceful monsters to become hostile, and has a chance of making tame monsters hostile as well. The chance of the latter happening is much higher if a tame monster has been abused or its tameness is low;
 
−
*[[Divine wrath]], requires the monster to be at least level 23; the player's [[god]] becomes [[anger|angry]] (randomly increases anger by 1–3 points) and [[smiting|smites]] the character.
 
−
The Call Undead arcane monster spell isn't restricted to liches in Slash'EM Extended. Instead, all arcane spellcasters that are at least level 10 can cast it. Also, the Wizard of Yendor has a small chance of casting Triple Trouble if there are two active wizards in the game.

Revision as of 10:20, 21 July 2022

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;[1] they will attempt to cast spells if these conditions are not met, producing a "curse" message.[2] 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).[3]

Monsters that are scared (e.g., by Elbereth) or are not adjacent to you[4] will not use directed spells. If a monster uses a directed spell at you, but you are on a different square than the monster expected, the spell will fail and produce a "curse" message.

Monsters will never cast spells (even not directed at you) if they're more than 7 squares away from you.[5]

Messages

<Monster> points at you, then curses.
<Monster> points all around, then curses.
The monster attempted to cast a spell before they were able to do so.
<Monster> points and curses in your general direction.
As above, but the monster cannot see you.
<Monster> points and curses at your displaced image.
As above, but you are displaced.
You hear a mumbled curse.
As above, but you cannot see the monster.
The air crackles around <monster>.
The monster cast a spell when able to do so, but the spell failed.
<Monster> casts a spell!
<Monster> casts a spell at you!
The monster successfully cast a spell.
<Monster> casts a spell at a spot near you!
As above, but the monster cannot see you.
<Monster> casts a spell at your displaced image!
As above, but you are displaced.

Spells

There are three categories of spells that monsters can cast: ray-type spells, mage spells, and clerical spells. In vanilla, no creature casts 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 two Monsters column. In the Monsters (at lowest level) column, we assume that the monster is generated at its base level minus one, which is the lowest possible level at which a monster will be randomly generated. In the Monsters (at highest level) column, we assume that the monster is generated at its base level times 1.5, which is the highest possible level at which a monster will be randomly generated. In both cases, 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. As an example, a golden naga is guaranteed to be able to cast Psi bolt, Cure self, Haste self, Stun, Disappear, Drain strength and Destroy armor. It may be able to cast Curse items and Aggravate, if it is generated at a high enough level.

Monster spellcasting abilities are dependent on their current level, not their original level, so draining a monster will remove its ability to cast higher-level spells. However, most important spellcasters are immune to life drainage, and those that aren't generally have very high MR, making the spell nearly useless. Stormbringer and the Staff of Aesculapius bypass monster MR, though both will kill most non-resistant monsters quickly enough that the effect on their spellcasting is not generally that noticeable.

Ray-type spells

Ray-type spells come in three varieties[6] (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 in vanilla has this attack.

Variants

SLASH'EM

SLASH'EM has many new spellcasting monsters, including fire vampires which use the previously-unimplemented fire ray spell. It also introduces two new mage spells:

FIQHack

In FIQHack, monsters use the same spellcasting system as the player, and can also read spellbooks to acquire new spells. This makes higher-level spellcasting monsters much more dangerous. Low-level spellcasting monsters (kobold shamans, orc shamans and gnomish wizards) no longer approach you due to lacking melee ability, and will instead attempt to line up with you in order to cast spells.

EvilHack

In EvilHack, if you are polymorphed into a monster with spellcasting attacks in their routine and you have enough spare power, attacking in melee will cause you to randomly use one of their available spells; the spellcasting attack fails if you do not have enough power.
