A rough draft. Comments welcome.
Modern arcane magic has its roots in older, simpler magical traditions - the magic of the witch.
Prime Requisite: CHA.
Hit Dice: 1d4.
Maximum Level: 14.
XP: 2,500 to reach 2nd level.
At first level, witches hit an unarmored foe (AC 0) with an attack throw of 10+. They advance in attack throws and saving throws only two points every six levels of experience (i.e., half as fast as fighters). They may only fight with clubs, daggers, darts, and slings. They are unable to use shields, fight with two weapons or two-handed weapons, or wear any kind of armor.
In exchange for these weaknesses, witches can learn and cast many powerful arcane spells. The number and levels of spells the witch can use in a single day are the same as a mage. The witch's repertoire can include a number of spells up to the amount listed for the witch's class level, increased by CHA bonus. For instance, Rawn, a third-level witch, is able to cast two level-1 spells and one level-2 spell per day. With a CHA 16 (+2 modifier), she can have a repertoire of up to four level-1 spells and three level-2 spells.
At first level, the witch gains a Familiar (as the proficiency).
Witches cannot use arcane magic items intended exclusively for mages (such as many wands and staffs); cannot read scrolls; and do not benefit in magical research throws from the presence of a library.
At third level, the witch gains the ability to brew herbals. Herbals can be identified as if they were potions (alchemists cannot assist in making them, however). Herbals produce a one-use spell effect, and cost 250 gold per spell level, and take one day per spell level to craft. Once crafted, they last for one month.
At fifth level, the witch gains the ability to research new spells. The witch's spell design multipliers are different from the mages: blast x1.5, death x1.5, detect x1, enchantment x1 (affecting undead x1.5, affecting animals x0.66), healing x1.5, illusion x1, movement x1 (teleport x1.5), protection x1, summoning x0.66, transmogrification x0.66, wall x1.
Also at fifth level, the witch gains a +1 to surprise rolls when in the wilderness.
At seventh level, the witch gains the ability to bind spells into the familiar. This is functionally similar to a scroll (the witch may "read out" the bound spell from the familiar in order to cast it), but only costs 250 gold per spell level, and takes only one day per spell level to bind. A familiar with bound spells can only be used in this way by the familiar's own witch (as a Class proficiency, a familiar may gain the ability to make a proficiency throw of 3+ to use a spell bound into itself; failure uses up the bound spell anyway and backfires in some way).
At ninth level, the witch is able to create more powerful magic items.
Also at ninth level, the witch can build a sanctum, which must be in a borderlands or wilderness region. Upon construction, the adventurer attracts 1d6 apprentices of level 1–3, plus 2d6 normal men seeking to become witches. Apprentices work exactly as for mage sanctums. Once a witch stronghold is established, all ordinary animals within five miles of the sanctum become kind and helpful.
At 11th level, a witch may learn and cast ritual arcane spells of great power (7th, 8th, and 9th level), bind elementals, and create permanent curses.
Witches who reach 11th level may bind elementals into service. The elemental may not have more hit dice than the witch's class level, and may not have more special abilities than the witch's CHA bonus, plus one.
It requires 2,000 gold per hit die, plus 5,000 gold per special ability, to bind an elemental, and the process takes one day per 1,000 gold.
Binding an elemental requires a magic research throw. The throw is increased by +2 per 5,000 gold of value in the elemental. A witch gains no benefit from precious materials.
By default, the elemental is bound for 33 days; the magic research throw can be increased by +2 to bind the elemental for 101 days; +4 for one year; +6 for three years; +8 for ten years; +10 for 33 years; and +12 for 101 years.
Summoning and binding an elemental also requires a ceremonial space at least equal in cost to the elemental it will be used to bind. For each 10,000 gold value above this amount, the ceremonial space grants a +1 on the magic research throw.
On a success, an elemental is summoned and bound. A bound elemental must obey the witch (or whomever the witch commands it to obey) for the period stated. Some elementals will be happy to serve the witch; others will interpret the letter of their commands as awfully as they can - make a reaction roll upon completing the binding to determine the elemental's attitude about its service.
A permanent curse is a special type of ritual spell. It has the following effects and modifiers. All effects last only for the duration of the curse (see duration) or until the curse is broken.
Remove curse can only remove a permanent curse if the curse-caster is of lower level than the remover; and even then, there is a 5% chance per level of the curse-caster that the removal will fail. If it fails, it cannot be attempted again by that remover for one year or until another level is gained, whichever comes first.
Permanent curses never allow saving throws.
