ToME: the Tales of Maj'Eyal

Music

Notes on Music spells:

Most Music spells are lasting effects; they consume the specified amount of mana each turn they are in effect, and remain in effect until explicitly canceled by the player.
Music spells are annotated with a Roman numeral indicating their "instrument level"; they can only be cast from an instrument with the specified (or higher) pval.
The spell stat for Music spells is CHA.

Stop Singing(I) (level 1, mana 0; fail -400%)

Cancels any lasting spell effect.
Song of the Sun(I) (level 1, mana 1, fail 20%)

Holding Pattern(I) (level 1, mana 1:10, fail 20%)

Casts a lasting slow effect; every turn that the spell is in effect, attempts to slow all monsters in line of sight, with power 10+(E@100:1) (see notes on slowing below). The slowing effect is cumulative; a monster's speed is decreased by 10 every time it fails to resist the spell.
Blow(I) (level 4, mana 3:30, fail 20%)

God spells

Assorted notes on god spells:

Minimum required skill level and spell effect level are computed based on the Prayer skill. All god spells receive a bonus to spell effect level based on your Spell-power skill, as described for school spells above.
God spells use piety rather than mana. The "piety M:N" notation used below mirrors the "mana N:M" notation used for school spells above.
The spell stat for all god spells is WIS.

Eru Iluvatar

[see also: Mana, Divination, Mind]

See the Music (level 1, piety 1:50, fail 20%)

Wind Shield (level 10, piety 100:500, fail 30%)

Confers temporary protection from evil with duration 10+E+1d20; if your level is L, then a level-M evil monster will be unable to hit you with probability 50+L percent if L?M. If E?10, also casts a shield effect with the same duration and +(E@30:1) armor class. If E?20, the shield effect does unresistable damage (1+(E@2:1))d(1+(E@6:1)).
Manwe's Call (level 20, piety 200:500, fail 40%)

Summons a friendly Great eagle, leveled to monster level 20+(E@70) (see notes on monster leveling below).
Avatar (level 35, piety 1000, fail 80%)

Melkor Bauglir

[see also: Mind, Udun]

Curse (level 1, piety 50:300, fail 20%)

Has the following effects on the targeted monster:

Reduces the "dice" and "sides" of all melee attacks by 1 (or 2 if E?50 and both are at least 2) -- for instance, an attack doing damage 2d5 would now do damage 1d4, or 0d3 if E?50.
If E?15, reduces armor class by E, to a minimum of -70.
If E?25, reduces speed by (E@7:1), to a minimum of -30 (one-third normal speed).
If E?35, reduces max hit points by an amount dependent on the monster race, to a minimum of 1.

If E?5, you are currently praying to Melkor, and your current piety is greater than 5000, there is a chance that these effects will be applied automatically (at no piety cost) each time you hit a monster with a melee attack; the probability of this is (W*(E@100:1))/M percent, where M is the monster's level and W is your WIS scaled to 30 (see below for the definition of this).
Corpse Explosion (level 10, piety 100:500, fail 45%)

Mind Steal (level 20, piety 1000, fail 90%)

Attempts to take control of a targeted monster's actions. The monster will resist with probability M-E+1 in M, where M is the monster's level.

Water Bite (level 20, piety 150:300, fail 90%)

Casts a projection effect with duration 30+(E@150:1)+1d30, radius 1 if E?25 or 0 if E<25, and base damage 10+E. The damage is water.
Uproot (level 35, piety 250:350, fail 95%)

Converts an adjacent tree square to a friendly Ent, leveled to monster level 30+(E@70:1) (see notes on monster leveling below).

Miscellaneous spell effects

Blessing, heroism, super-heroism

These are all efffects that temporarily boost combat ability:

Blessing confers +5 to armor class and +10 to-hit. It is conveyed by Scrolls of Blessing (hence the name), Holy Chant, and Holy Prayer.
Heroism confers +12 to-hit, resist fear and +10 max hit points. It is conveyed by Potions of Heroism (hence the name).
Super-heroism convers +24 to-hit, -10 to armor class, resist fear and +30 max hit points. It is conveyed by Potions of Berzerk Strength.

Charming, confusion, stunning, slowing

These are effects that can be resisted by a monster with a probability based on the monster's level and the power of the spell. If a spell with power P is cast on a level-M monster, then:

The monster will resist a charm spell with probability M-1 in P-5. If the spell only affects certain types of monsters, like animals or demons, this probability reduces to M-1 in P. Note that uniques, quest monsters, and monsters that resist confusion cannot be charmed by spells of this sort.
The monster will resist a confusion spell with probability M-1 in P; if it does not resist, its confusion timer is set to 1+3d(P/2) if it is not already confused, or increased by half that amount if it is already confused, to a maximum of 200 game turns.
The monster will resist a stun spell with probability M-1 in P; if it does not resist, its stun timer is set to 1+(L/10+3)dP if it is not already stunned (where L is the player's experience level), or increased by half that amount if it is already stunned, to a maximum of 200 game turns.
The monster will resist a slow spell with probability M-1 in P; if it does not resist, its speed is decreased by 10. Note that uniques are immune to this effect.

Invisibility

Unlike in some of its predecessors, invisibility in ToME is not a binary effect; it has a power level, which determines how powerful a monster must be to see through your invisibility. This is computed as follows: Let I be your total invisibility power and M be the monster's level, modified as follows:

M=M+10 if the monster is immune to sleep
M=M+20 if the monster is a dragon
M=M+15 if the monster is undead, a demon, or an animal
M=M-15 if the monster is an orc
M=M-10 if the monster is a troll
M=M/2 if the monster is stupid
M=(M*5)/4 rounded down if the monster is smart.
I=0 if the monster is invisible, a quest monster, or under your control

Then the monster will be unable to see you with probability I in M×2.

Invisibility power conferred by worn items are cumulative with each other and with temporary invisibility power; temporary invisibility effects are cumulative in time, using the power of the most recently activated temporary effect. For comparison, here are the power levels of common sources of invisibility:

Rings of Invisibility have power 40.
Artifacts and ego items that provide invisibility have power 10 times their pval.
An invisible symbiote confers invisibility power 20.
An invisible possessed body confers invisibility power 20.
Invisibility provided by Melkor for high piety has power 30.
Potions of Invisibility confers temporary invisibility of power 35.
The Invisibility Mimicry power confers temporary invisibility of power 50.

Leveled monsters

Monsters in ToME can gain levels and become more powerful by killing monsters to gain experience, much like the player does. In some cases (the Angband dungeon, some relic quests), monsters are artificially raised to a higher level on creation; such a monster is described herein as "leveled to monster level N". Each time a monster gains a level, it may gain any or all of the following modifications:

With proability 80%, it gains one "die" of hit points and max hit points. For instance, a Kobold, whose normal hit points are 3d7, would gain 7 hit points and 7 max hit points.
With probability 40%, it gains +1d2 speed.
WIth probability 50%, it gains +A/10 armor class (rounded down to the nearest integer, with a minimum of 1), where A is the monster's starting armor class.
With probability 30%, one of its first three melee attacks is increased by one "die". For instance, a Kobold's 1d8 attack would increase to 2d8.

For a "leveled" monster, these effects are applied once for each difference in level between the monster's default level and the target level (if the latter is less than the former, no change is made). This can produce some truly horrific monsters: a Kobold (default monster level 2) leveled to monster level 50, for instance, will on average have 3d7+268 hit points, +29 speed, armor class 40 and a 15d8 melee attack.

Stat-based adjustments

Some of the effects described above include stat-based adjustments; for reference, we list here the numerical amounts of said adjustments. For some purposes (mostly table lookup), a stat value is converted internally to a stat index, as delineated in the second column.
Stat Stat index Min fail rate Fail rate adj
3 0 99% 0
4 1 99% 0
5 2 99% 0
6 3 99% 0

18/210-18/219 36 0% 18
18/220+ 37 0% 19

Another stat-based concept sometimes used in the game is that of a "scaled" stat. This will be denoted herein as a stat "scaled to N", and is defined as (I×N)/37, rounded down to the nearest integer, where I is the stat index of the stat in question, as listed above.
