Low level Magic Users have only a few spells. Once all the spells are cast, their contributions to the party can be very limited. Here are some options to increase Magic User proficiencies/fun in a campaign. Three are by-the-book, the last is a house rule.
By-The-Book:
1. Scroll creation at 1st level:
Holmes pg 13. “Magic
users may make a scroll of a spell they already "know"
(i.e. have in their magic book) at a cost of 100 gold pieces and 1
week's work for each spell of the first level, 200 gold pieces and 2
weeks for a second level spell.”
2. Move and Cast:
Gazetteer 3 pg 59.
“Agility Training: This allows the magic-user to roll (d20) under
his Dexterity to be able to cast spells while moving. This can only
he done at a normal walking pace; riding a mount or dodging attacks
imposes a severe penalty on the ability check (DM's discretion, a -1
to -10 to the Dex score. depending on circumstances). If the attempt
fails, the spell is lost.”
3. Combining Spell
Levels:
Gazetteer 3 pg. 59
“Spell Combination: This technique allows the student to mix his
spell levels in any combination, so long as the total spell levels
memorized do not exceed his capacity. For example: a level 4
magic-user normally casts two 1st level spells, and two 2nd levels
(for a total of 6 spell levels).With this technique, he can choose to
memorize six first level spells. Or three second levels, or any other
appropriate combination.”
Casting House Rule
by Finarvyn/Firebee:
Free cast-power point system. All types of spell casters are allowed
to free cast. They don't need to choose spells beforehand. Magic
Users/Elves are limited to the spells in their book.
Just total the spell
slots you have available per level and that's your power pool. A
first level spell is worth 1 point, a 2nd level spell is
worth 2 points and so on. Then any spell you cast, deducts that level
from the power pool (i.e. a 3rd level spell uses 3 points). You are
still limited to the maximum number of spells your character can
cast. So a 4th level MU would have 6 spell points and
could cast a total of 4 spells.
To make the system a
little more fun, give each player a plastic gem for every spell they
can cast, and a plastic coin for every spell point. When they cast a
spell, they simply give the DM a gem and the appropriate number of
coins. It's a pretty easy way to keep track of spells and spell
points.
