Spellcasting Abilities

Daily spell lists for spellcasters.

Each day a spellcaster prepares a list of spells for each spell level that he can cast 'spontaneously' as he chooses. For example, a second level wizard with 15 intelligence can cast 4 0-level and 4 1st-level spells per day. He would thus choose a 'list' of four cantrips and four first level spells, and could cast any combination of those four cantrips and four first level spells that day (though cantrips cannot be cast in place of first level spells, and vice versa). For example, say the wizard prepared for his first level spells burning hands, charm person, identify, and spider climb. He could then cast each of those spells once that day, cast identify four times (and not cast any of the others at all), or cast burning hands twice and spider climb twice. This option obviously makes spellcasters a bit more versatile, but is balanced by the fact that many spells will be unavailable. (FYI I got this option from the 3E UA. See p. 153 for a more complete description.)

Wizard staffs and Illusionist wands.

Arcane spellcasters require no material components or normal 'spell books'. Instead, the wizard's focus is his staff. The wizard can choose one spell from each spell level known (i.e. one 0 level spell, one 1st level spell, etc.) that he can cast without his staff, but for all other spells he needs his staff. Moreover, all arcane magic is rune-based (so scrolls and books found typically contain runes of spells). As the wizard learns more spells, he carves these runes into his staff, so the staff serves the role of a 'spell book'. The exceptions are those spells he can cast without his staff -- those are tattooed onto the wizard himself (his hands and arms). As a consequence, the wizard is heavily dependent on his staff (this is the main constraint he faces, to balance the increased flexibility gained from the 'spell list' house rule I am using, and to keep the sorcerer more or less balanced with the wizard). The wizard's staff is considered a magical item, and has a spell resistance of 15 + the wizard's level. Spells like 'shatter' and 'warp wood' would have to overcome that resistance to work. Illusionists are like wizards, except they use multiple wands instead of a single staff (and normally try to conceal their wands 'up their sleeves' and whatnot).
