Yet Another Magic Rework
I have mad an attempt to consolidate, update, and add a bit of depth to the existing magic system. This is always a point of contention with my Wizards whenever I get a group together. Everybody else gets to go shopping and gear up, except them. Below is what I've got so far. Please bear in mind that this is very much a work-in-progress. That being said, I am 100% open to feedback of any kind. DISCLAIMER: I am a big fan of mash-ups and crossovers. To that end you will probably notice that I am incorporating elements from the greats. This will amuse some and annoy others, and that is okay. In the event this little project becomes something more than a 9-layer nerd burrito intended for private consumption, I will sanitize it of all relevant IP. Until then, let the good times roll. 
Now, lets get down to business...
MIND POINTS
A Hero’s Mind Points is a combined rating of their INTELLEGENCE, WISDOM, and CHARISMA. Some spells and environmental effects can use your Mind Points to determine if you are smart/tough enough to survive them, or to what extent you are affected. To better illustrate how a Hero’s Mind Points score translates, here are some examples. Unless stated otherwise, these examples pertain to Heroes only (human, elf, dwarf, and gnome) and do not include monsters, mercenaries, or other NPCs.
0) You are unconscious, brain dead, or undead.
1) Primitive intelligence, includes very basic problem solving and crafting ability.
2-3) Average intelligence for most major races.
4-5) Above-average intelligence, likely has had some formal training in the use of magic.
6-8) Advanced intelligence, likely a graduate of the Mage’s College.
9+) Extremely advanced intelligence, likely on the way to becoming an Arch Mage.
MAGIC & SPELLCASTERS
Magi’s Guild: All Heroes who cast spells, regardless of their Job Class, are members of the Magi’s Guild. The only exception are Elves who only know a single racial spell. Your Mind Points score determines your magical aptitude, the potential extent of your spell inventory, and what types of Artifacts/Magic Items you can train for and equip.
1-3) You are unable to grasp even the basics of magical theory (no spells).
4) You have a natural/intuitive understanding and talent for the mystical arts (one spell group).
5) You are an Apprentice of the Magi’s Guild (two spell groups).
6) You are a Journeyman of the Magi’s Guild (three spell groups).
7) You are an Expert of the Magi’s Guild (five spell groups).
8) You are a Master of the Magi’s Guild (seven spell groups).
9) You are an Arch-Mage of the Magi’s Guild (all spell groups).
Off Limits: Job Classes not listed in Hero Creation are considered NPC classes, and not available for player use. Chaos spells are only available to NPCs.
Spells Groups: There are four core spell groups (Fire, Water, Earth and Air), three advanced spell groups (Divination, Protection and Shadow), and one legendary spell group (under construction). Each group comprises a Book of Magic.
The first seven Books all contain three spells, while the legendary spells can only be collected individually. During Hero Creation, a Wizard must choose three of the core groups to start with.
As you advance, you may purchase additional Books from the Mage’s Guild. As you collect new spells you will need to determine which you wish to prepare for use during your next quest.
Your Mind score determines the number of spells you may use per quest.
Unless stated otherwise, you may only cast any given spell once per quest.
Magi’s Equipment: Since stripping a spellcaster of her equipment removes her ability to cast spells entirely, this would indicate that she needs a physical means of casting. You must obtain and equip an appropriate item to be able to cast your spells at all.
I. Wands – Wands are the baseline equipment for spellcasters. They provide a means of targeting, focusing, and executing a Wizard’s spells. Like the Wizard, however, its power is exhausted through the casting of those spells. Even the best quality wands only have 9 good charges in them before they're exhausted. For simplicity sake, wands are reusable and automatically recharge between quests.
II. Wizard's Staff – Not to be confused with the mundane Quarterstaff. A proper Wizard’s Staff is a bit harder to come by, but worth the effort to obtain. They have the same number of charges as a wand, but gain the advantage of an additional physical attack. These are two-handed weapons.
III. Rods – Also known as “blasting rods,” these powerful upgrades from basic wands are extraordinarily difficult to create and maintain. They are rare and incredibly expensive tools of destruction. In addition to casting spells (up to 12 per quest), they also allow their owner to harness their sheer force of will as a weapon. Rods get a ranged attack (LoS, except adjacent) with 2 combat dice. Any damage dealt is normal physical damage, and is defended as if it were from a non-magical weapon.
IV. Grimoires – There is no substitute for the classic spell book, or grimoire. These heavy and voluminous tomes represent the sum total of knowledge of the most renowned masters of magic. They allow advanced Wizards to cast their full catalog of spells during a quest. Though a book this size might do a bit of damage in combat, its contents are too precious to risk on such an attack. Instead, a grimoire is heavily enchanted with protection spells, and those protections extend to its wielder. This two-handed item reduces your attack to 0, but grants you +1 to your defense.
RACIAL ABILITIES
These are excerpts from this section specific to magic.
Races with innate magical ability do not require equipment to cast racial spells or abilities. Learned magic still requires the proper tools to utilize.
Elf Spells may be copied onto Spell Scrolls, but cost twice as much to create.
Considering changing "racial" and "Elf Spells" to "Fey magic" and "Book of Fey"...
Elven access to racial spells depends on Mind Points score (as above), but you may only ever prepare three of these spells to take with you on a quest.
1-3) You gain only one Elf Spell, chosen during Hero Creation, and cannot be changed.
4-5) You gain three Elf Spells, chosen during Hero Creation.
6-7) You gain three additional Elf Spells.
8-9) You know all eight Elf Spells.
Gnomes may select any one spell (including Elf Spells) during Hero Creation. They may use this spell once each quest, and never need equipment to cast it.

That last bit is pending. I might leave out 'minimum requirements' in favor of class restrictions to keep things simple. Adding too much to the game defeats the purpose, as at a point it would be easier to just play Pathfinder.
