Sorcerers are supposed to cast from their own personal 'mana pool', so it doesn't make a lot of sense that cantrips and level 1 spells would do anything to 'drain' an epic sorcerer. I think that epic sorcerers should get unlimited castings of Cantrips and Level 1 spells. I think they should also get a lot more access to PnP cantrips and level 1 spells. These are supposed to be simple magical effects. It doesn't make sense that a sorcerer wouldn't be able to access them.

The source of a sorcerer's abilities should be a pretty major part of the class. I think we should introduce bloodlines to Amia that would grant bonus abilities and weaknesses depending upon the bloodline of a sorcerer. If your sorcerer is a sorcerer because they have the blood of a dragon/fey/outsider/whatever in them, they should get abilities that reflect that heritage.

I think sorcerers should have much more control over their magic than any ordinary wizard does. A sorcerer's magic is an extension of his/her will. It shouldn't be static or restrictive. If a sorcerer can produce a fireball, he should also be able to generate a simple flame from his hand to light a campfire.

Sorcerers are supposed to be innately magical beings. It really doesn't make sense that they get so very little skill points to devote to 'caster' skills like Spellcraft. I think the class should get bonus Skill Focus feats in the caster skills to make up for that.

One gained at 7, 14, 21 and 28. Energy Resistance, Arcane Defense, and Battle-Tested can be taken multiple times, as long as it is a different Energy/School/Weapon.

1. Spell Sweep:
A sorcerer finds that by using their natural magic in different ways, they can alter its application and shape. When casting a cone spell, they can choose to move their hands around, thus hosing down an area around them, rather than directly ahead. By casting any Cone Spell on himself as a target, the sorcerer changes the AoE of the spell into a 10 foot circle around his body. Affected Spells: Cone of Cold, Mestil’s Acid Breath, Prismatic Spray, Color Spray, and Burning Hands.

2. Ricochet
The sorcerer becomes adept at adapting certain ballistic spells to be more useful. Ray spells now function as Line attacks, affecting enemies similar to the way Lightning Bolt targets enemies. Projectile burst spells can "skip" off the ground once; if there is an enemy just outside the radius of the spell's "first" AoE, it will be cast again, once, at the nearest enemy that was not in the original AoE. Affected Spells- Ray: Ray of Cold, Negative Energy Ray, Ray of Enfeeblement, Ice Dagger. Affected Spells - Bounce: Fireball, Scintillating Sphere, Delayed Fireball.

3. Channel Spell
The sorcerer's magic flows forth like a river, bound only by their continuous will. When casting a spell in Defensive Casting mode, all hostile spells immediately repeat the next round, taking another appropriate spell slot, unless the caster moves or queues a different action. A Channeled Spell can only be Counterspelled at its initial casting; a channel already in progress cannot be countered. However, Channeling does require a concentration check. It can be broken by moving or receiving damage and failing the damage vs Concentration save.

4. Weapon Channel:
When connecting with a touch attack spell, the target also takes one generated “hit” from the Sorcerer’s main hand weapon. Affected Spells: Vampiric Touch, Combust, Ghoul Touch.

5. Resist Energy:
The sorcerer gains resistance to the element most aligned to his ancestors or paradigm. As per the normal feat, though the Sorcerer automatically meets the prerequisites when taking it as a bonus feat.

6. Allure:
Befitting of her ancestors, the sorceress is naturally gifted in wiles and charm. She gains a bonus to Persuade and Bluff equal to half her CL.

7. Imperious:
Like those that came before him, the sorcerer is naturally domineering and imposing. He gains a bonus to Intimidate and Taunt equal to half his CL.

8. Claws:
A manifestation of their draconic/feral/outsider heritage, the sorcerer gains sharpened nails and fingertips. His unarmed attacks deal extra damage. This works as per the feat Weapon Specialization: Unarmed Strike (+2 to unarmed damage) and Improved Unarmed Strike.

9. Animal Magnetism:
While many sorcerer’s power stems from worlds away, this one is born of the earth and her creatures. She gains Animal Empathy as a cross-class skill and Trackless Step as the default feat.

10. Battle-Tested:
Given that their magic comes so naturally, the Sorcerer has even more time to focus on the grittier aspects of combat. PC gains Weapon Focus in one Simple Weapon or Unarmed.

11. Arcane Defense:
The sorcerer becomes more hardened against spells related or opposing their paradigm. As per the Arcane Defense feat.

12. Changeling:
Any spells of the Polymorph subschool are automatically treated as Extended. Does not stack with Extend Spell. In addition, this qualifies the PC to take Shifter as a prestige class, if the Sorcerer knows Polymorph Self or Shapechange.

Instead of Spells per Day, Sorcerers receive a pool of "points" based off of their class level and CHA modifier. When a spell is cast, its Spell Level is subtracted from the total. Cantrips, being 0-Level Spells, consume no points.

WIZARD SPELLS
Wizard spells range from spells of simple utility to great and powerful magics. The
wizard spell group has no single theme or purpose. The vast majority of wizard spells
were created by ancient wizards for many different purposes. Some are to serve the
common man in his everyday needs. Others provide adventurers with the might and
firepower they need to survive. Some are relatively simple and safe to use (as safe as
magic can be); others are complicated, filled with hazards and snares for the rash and
unwary. Perhaps the greatest of all wizard spells is the powerful and tricky wish. It
represents the epitome of spell-casting--causing things to happen simply because the
wizard desires it to be so. But it is a long and difficult task to attain the mastery needed to
learn this spell.
Although some characters can use spells, the workings of magic are dimly understood
at best. There are many theories about where the power comes from. The most commonly
accepted idea is that the mysterious combination of words, gestures, and materials that
make up a spell somehow taps an extradimensional source of energy that in turn causes
the desired effect. Somehow the components of the spells--those words, gestures and
materials--route this energy to a specific and desired result. Fortunately, how this happens
is not very important to the majority of wizards. It is enough to know that "when you do
this, that happens."
Casting a wizard spell is a very complicated ordeal. The process of learning the correct
procedure to cast a spell is difficult and taxing to the mind. Thus, a wizard must check to
see if he learns each new spell (according to his Intelligence--see Table 4). Furthermore,
there is a limit to just how much of this strangeness--illogical mathematics, alchemical
chemistry, structuralist linguistics--a wizard's mind can comprehend, and so he must live
with a limit to the number of spells he can know.
As the wizard learns spells, he records their arcane notes into his spell books. Without
spell books, a wizard cannot memorize new spells. Within them are all his instructions
or memorizing and casting all the spells he knows. As the wizard successfully learns a
new spell, he carefully enters its formula into his spell books. A wizard can never have a
spell in his books that he does not know, because if he doesn't understand it, he cannot
write the formula. Likewise, he cannot enter a spell into his books that is higher in level
than he can cast. If he finds an ancient tome with spells of higher power, he must simply
wait until he advances to a level at which he can use them.
The exact shape and size of a character's spellbooks is a detail your DM will provide.
They may be thick tomes of carefully inked parchment, crackling scrolls in bulky cases,
or even weighty clay tablets. They are almost never convenient to carry around. Their
exact form depends on the type and setting of the campaign world your DM has created.
Ultimately, it is the memorization that is important. To draw on magical energy, the
wizard must shape specific mental patterns in his mind. He uses his spell books to force
his mind through mental exercises, preparing it to hold the final, twisted patterns. These
patterns are very complicated and alien to normal thought, so they don't register in the
mind as normal learning. To shape these patterns, the wizard must spend time
memorizing the spell, twisting his thoughts and recasting the energy patterns each time to
account for subtle changes--planetary motions, seasons, time of day, and more.
Once a wizard memorizes a spell, it remains in his memory (as potential energy) until
he uses the prescribed components to trigger the release of the energy patterns. The
mental patterns apparently release the energy while the components shape and guide it.
Upon casting, the energy of the spell is spent, wiped clean from the wizard's mind. The
mental patterns are lost until the wizard studies and memorizes that spell again.
The number of spells a wizard can memorize is given by his level (see Table 21); he
can memorize the same spell more than once, but each memorization counts as one spell
toward his daily memorization limit. Part of a wizard's intelligence can be seen in the
careful selection of spells he has memorized.
Memorization is not a thing that happens immediately. The wizard must have a clear
head gained from a restful night's sleep and then has to spend time studying his spell
books. The amount of study time needed is 10 minutes per level of the spell being
memorized. Thus, a 9th-level spell (the most powerful) would require 90 minutes of
careful study. Clearly, high-level spellcasters do not lightly change their memorized
spells.
Spells remain memorized until they are cast or wiped from the character's mind by a
spell or magical item. A wizard cannot choose to forget a memorized spell to replace it
with another one. He can, however, cast a spell just to cleanse his mind for another spell.
(The DM must make sure that the wizard does not get experience for this.)

A rapidly growing number of individuals, however, master arcane practices that ignore the act of spell preparation. These characters instead focus their talent in learning a narrow range of spells, comprising a limited scope of effects. Instead of spending long hours poring over spellbooks, these casters need mere minutes each day to ready their magical potential. One can't help wondering if this represents merely a passing fad or an evolutionary "sea change" in arcane magic as a whole

But why so many components? Although arcanists have historically claimed that these incantations and magic powders are akin to keys—necessary to unlock the final effect of a spell—another, new theory has begun to gain ground among younger researchers. These energetic sages assert that components aren't keys, but rather locks—suggesting that even the most learned of arcanists don't fully control their own powers, and that components are necessary instruments to keep the spells in check. Whether these locks were placed by the deities themselves or are simply such an old convention that no one today questions their utility is anyone's guess.

All spells share the characteristics discussed earlier, but all spells aren't alike. To the layperson, there's not much difference between the spells wielded by a wizard and those cast by a cleric. To the student of magic, however, profound differences abound. Divine spellcasters draw their magical power through a specific source that serves as both a conduit and a filter. As the name suggests, the source has a divine nature, whether a deity, a whole pantheon of gods, or merely a powerful cause or ideal. Regardless of the actual source, divine magic is intensely personal and comes to the user through devotion to a concept such as law, war, or truth, or to some aspect of the universe, such as nature. Put simply, to a divine spellcaster magic is a matter of faith, not learning. Interestingly, the source of the magic seems to have little or no impact on the resulting effect. The protection from evil spell cast by a cleric functions identically to that cast by a sorcerer, even though each caster would claim that his spell results from a different power. This isn't to say that arcane and divine magic have no differences, but rather that the differences appear in flavor instead of effect. The mystical gestures required by divine spells tend to be less expansive and complicated than those of their arcane counterparts, but no compelling theory explains why. Those who hold to the "component as lock" theory (mentioned above) suggest that divine casters need fewer innate restrictions on their spells, since a higher power has already entrusted them with the effect. For a divine spellcaster, preparing a spell is mostly a matter of the spirit. The spellcaster prays or meditates, entreating the divine source to provide power for the spell. Arcane spellcasters, on the other hand, see preparing a spell as an intellectual exercise. The arcane spellcaster ponders the spell's intricacies and builds it within his or her mind, piece by piece. Divine casters must also obey certain strictures on their use of magic, varying from limited access to spell preparation (typically to a particular time of day associated with the source) to outright restrictions (such as the inability to use spells opposed to their alignment). Rare is the divine spellcaster who doesn't have to deal with at least one quirk that an arcane caster might find quaint or even outright annoying. Curiously, one arcane caster—the wu jen—shares a similar stricture in the form of taboos. This similarity suggests that the origins of the wu jen's magical talents might lie closer to the province of the divine than commonly accepted. Despite the different methods arcane and divine casters use to prepare and cast their spells, it's worth remembering that both groups ultimately tap the same source of magical power. Once a spell has been cast, it's effectively impossible to tell whether it is arcane or divine. If an observer actually witnesses the casting, the spell's components might give a clue to the spell's nature; for example, divine spells typically employ a holy symbol as a focus for the spell. Otherwise, nothing distinguishes an arcane spell effect from a divine spell effect.

Healing: Certain divine conjurations heal creatures or even
bring them back to life. These include cure spells.

Wizards, sorcerers, and bards cast arcane spells, which involve the direct manipulation of mystic energies. These manipulations require natural talent (in the case of sorcerers), long study (in the case of wizards), or both (in the case of bards). Compared to divine spells, arcane spells are more likely to produce dramatic results, such as flight, explosions, or transformations.

Clerics, druids, experienced paladins, and experienced rangers can cast divine spells. Unlike arcane spells, divine spells draw power from a divine source. Clerics gain spell power from deities or from divine forces. The divine force of nature powers druid and ranger spells. The divine forces of law and good power paladin spells. Divine spells tend to focus on healing and protection and are less flashy, destructive, and disruptive than arcane spells.

Wizards and sorcerers should not cast healing spells, but they should have the best offensive spells. If the spell is flashy or dramatic, it should probably be a wizard/sorcerer spell.
