A miscast effect occurs when a player fails to cast a spell successfully. These can range in severity from completely harmless to inflicting heavy damage and magic contamination, depending on the school of magic that is used.
Failure to cast spells causes various generally nasty things to occur, becoming nastier with spell level and spell failure. Miscasts come in a severity scale 0, 1, 2 and 3. 0 is always harmless, although it can occasionally make a moderate amount of noise.
Displayed in game spell failure rate color indicates the chances of getting severity 2 or greater miscast effects.

Torment, rotting, and draining damage have no effect on undead. For spells, no effect at all if Kiku** and Piety/150 chance. These effects are also frequently seen as death curses from non-plain mummies. For death curses, if Kiku**, then Kiku has a 1/2 chance of blocking it entirely, otherwise reduces the severity by one level.

- 2: Draining, 3 shadows, or 15-37 torment damage

Hell's mystical force selects a miscast or other effect with the probabilities given below. As noted further down, it will always try to place a Malign Gateway instead of banishing, as banishment is rarely more than annoyance for a character that can handle Hell.
- Necromancy miscast: 16.66%
- Summonings miscast: 8.33%
- Conjurations miscast: 4.16%
- Charms miscast: 2.08%
- Hexes miscast: 2.08%
- Miscast appropriate to each branch: 22.22% (Fire magic miscast in Gehenna, Ice magic miscast in Cocytus, Necromancy miscast in Tartarus, and Earth magic miscast in Dis)
- Summon a greater demon appropriate to each branch: 14.15% (Brimstone fiends in Gehenna, Ice fiends in Cocytus, Shadow fiends in Tartarus, and any greater demon in Dis)
- Summon 1-5 random monsters: 9.88%
- Nothing happens: 19.75%
- Only caused by normal miscasts, not by hell effects. Only when player is not sleep immune (undead, nonliving or berserk).
- Only caused by normal miscasts, not by hell effects.
- Attempts to banish. This fails if it's a Hell effect miscast, or if you're in the Abyss with a depth/5 chance. If it fails, attempt to place a Malign Gateway. If that fails, reroll the effect.
- If this fails to place, reroll.
