When '''[[spellcasting]]''' the '''Fail''' column appears in the menu which occurs when using the '''[Z]''' [[commands|command]].

To calculate [[spell]] '''failure''', you first need to sum together the penalties marked with a number sign (#) below. An increasing total penalty is worse for spellcasting, and is limited to a maximum of 20.

* The "BASE" value from the table below, depending on the character's class.
* If an "[[emergency]]" spell (noted with a + above), the "EMERG" field.
* If wearing any [[shield]], the amount in the "SHIELD" field.
* If wearing metallic [[armor|body armor]], the amount in the "SUIT" field.
* If also wearing a [[robe]], only add half the amount (rounded down).
* If wearing a robe without metallic armour, *subtract* the amount in the "SUIT" field.
* If wearing a metallic [[helmet]] other than the [[helm of brilliance]], add 4.(Metal helmets interfere with the mind.)
* Metallic [[gloves]] add 6 (casting channels through the hands).
* Metallic [[boots]] add 2 (all metal interferes to some degree).
* Add -4 if the spell is [[special spell|special]] to that class (see table).

CLASS BASE EMERG SHIELD SUIT STAT SPECIAL SPELL
Arc 5# 0# 2# 10# Int Magic mapping
Bar 14# 0# 0# 8# Int Haste self
Cav 12# 0# 1# 8# Int Dig
Hea 3# -3# 2# 10# Wis Cure sickness
Kni 8# -2# 0# 9# Wis Turn undead
Mon 8# -2# 2# 20# Wis Restore ability
Pri 3# -2# 2# 10# Wis Remove curse
Ran 9# 2# 1# 10# Int Invisibility

Sam 10# 0# 0# 8# Int Clairvoyance
Tou 5# 1# 2# 10# Int Charm monster
Val 10# -2# 0# 9# Wis Cone of cold
Wiz 1# 0# 3# 10# Int Magic missile

Next, calculate a base chance of success, which is 5.5 times your
intelligence or wisdom STAT, depending on your class. This chance is
modified by the following factors:
* SKILL level (Unskilled = 0, Basic = 1, Skilled = 2, Expert = 3)
* spell level (LVL)
* experience level (XL)
according to this formula:
difficulty = (LVL * 4) - (SKILL * 6) - (XL/3) - 5

If this is positive, your chance is reduced according to another formula:
chance = base chance - square root of ((900 * difficulty) + 2000)
If it is negative, it will be increased with diminishing returns: the
absolute value is multiplied by (15/LVL), capped at 20, and added to
the base chance.

The resulting chance is clipped to the range of 0% to 120% success. If
you are wearing a shield larger than a small shield, the chance is then
reduced to 1/4 its amount (except if it is the special spell for your
class -- then it is only halved).

Finally, the chance of success is adjusted by your total penalty using
the following formula:
chance = (chance * (20-penalty) / 15) - penalty
The result is clipped to the range of 0% to 100% success.
