This section contains optional guidelines for Labyrinth Lords on the subject of how elementalists (and, by extension, other wizardly characters) may gain access to and learn new spells.
For games in the vein of the traditional Basic rules, the following guidelines may be used:
* Elementalists begin the game knowing read magic, one randomly selected spell, and one spell of the player's choice.
* The number of spells an elementalist can know (i.e. record in his spell book) is limited to no more than double the number that he can memorize. For example, a 5th level elementalist can memorize two 1st level, two 2nd level, and one 3rd level spell. Such a character could have at most four 1st level, four 2nd level, and two 3rd level spells in his spell book.
* Upon gaining an experience level, if the elementalist does not already have spells available to learn (e.g. from scrolls or captured spell books), he automatically acquires knowledge of one new spell, selected randomly from a level of the player's choosing.
Advanced era games are more generous with the number of spells known and may use the following guidelines:
* Elementalists begin the game knowing read magic, two randomly selected spells, and two spells of the player's choice.
* The number of spells an elementalist can know (i.e. record in his spell book) is limited by the character's INT (see the AEC).
* Upon gaining an experience level, if the elementalist does not already have spells available to learn (e.g. from scrolls or captured spell books), he automatically acquires knowledge of one new spell, selected randomly from a level of the player's choosing. This spell must be learnt according to the normal rules for spell learning, again dependent on the character's INT.
The basic Labyrinth Lord rules describe a single type of arcane magic, usable by magic-users and elves. The Advanced Edition Companion and other books, such as this, add further, more specialised wizardly classes: illusionists and elementalists. These new classes acquire new spells in the same means as the standard magic-user: by finding spell scrolls in treasure hoards. When it is determined that a treasure hoard contains scrolls of magic-user spells, it is thus desirable that spells usable by specialist wizards also be (at least some of the time) present.
