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, the spell level, and the degree of failure. Players wishing to protect themselves from miscasts should focus on increasing the [[spell success]] rate, as this reduces both the frequency and intensity of miscasts. Additionally, miscasts from some schools of magic produce elemental damage that can be resisted. | A [[miscast effect]] occurs when a player fails to cast a spell successfully.

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, the spell level, and the degree of failure. Players wishing to protect themselves from miscasts should focus on increasing the spell success rate, as this reduces both the frequency and intensity of miscasts. Additionally, miscasts from some schools of magic produce elemental damage that can be resisted.
The in game spell failure rate color indicates the maximum potential damage relative to your current max HP. These are calculated as if the damage is irresistible, even for those schools whose miscast effects are resistible or not directly damaging.
| Color | Potential HP Loss |
Warning Description |
|---|---|---|
| Grey | None | safe |
| White | 0% - 10% | slightly dangerous |
| Yellow | 10% - 30% | dangerous |
| Light red | 30% - 50% | quite dangerous |
| Red | 50% - 70% | extremely dangerous |
| Purple | 70% - 100% | potentially lethal |
The spell description shows the full list of possible miscast effects, including maximum damage and damage types.
Effects
Miscasting a spell from any school causes contamination based on the spell level and degree of failure (which can range from 1 to 99 for spells that are almost impossible to cast; higher success rate reduces the maximum range):
Contamination: (Spell Level × Spell Level × Degree of Failure + 250) / 500
If this results in more than 0.8 points of contamination, an additional effect is applied based on the spell school. If the spell has multiple schools, one of them is chosen at random. The intensity of the effect is rolled based on the spell level and the raw spell failure chance (an internal value from 1 to 99, not the failure rate shown on the spell list).
Intensity: (Spell Level)d(Spell Level + Raw Failure Rate) / 9
For damaging effects, this is the amount of damage done. For status effects (slow and dimension anchor), this is the duration in turns. Other effects as listed:
| School | Effect |
|---|---|
| Air Magic | electricity damage |
| Conjurations | irresistible damage |
| Earth Magic | shrapnel damage (reduced by AC three times) |
| Hexes | debuff and slow |
| Charms | debuff and slow |
| Fire Magic | fire damage |
| Ice magic | cold damage |
| Necromancy | draining damage |
| Poison Magic | poison damage |
| Summonings | durably summoned nameless horror HD = 2 × Intensity / 3 |
| Translocations | Dimension Anchor |
| Transmutations | double current contamination plus 9 × Intensity / 1000 contamination |
