Wild Magic for Spells Chapter. Comments for revision needed.

Suggestions would be great. This system is based on Sean K Reynolds' wild magic on his website ( http://www.seankreynolds.com/ ), so a great thanks for the core mechanic.

Here it is nicely formatted. Gonna have to cut and paste...

Wild Magic
“The forces of chaos are best avoided.” Ex-Factol Hashkar of the Fraternity of Order spoke these words not more than three years before his death. Wild magic theorists understand these words, but for one reason or another choose to ignore them. Some fancy themselves pioneers in the field, willing to take the risks that others would not, all in the name of discovery. Others, those lacking in their character that vital bit of self-preservation required to survive on the planes very long, find bliss in constantly risking themselves and those around them to the untamable and fickle spirit of chaos. The truth is, every student of wild magic has his reasons, and no two students have the same reasons.
However, whatever an individual wild mage’s reasons for his entrance into the field might be, their goal is always the same--to push the limits of magic, bringing its very essence to its breaking point, with the goal of increasing their spells potency and versatility. Some see the greater wild surges (and their often dangerous effects) as a pleasantly surprising, while others see it as a glitch that must be stomped out to perfect their magical ability.

Rules
Wild Magic Zones.
In a dead magic zone, magic is suppressed to non-existence. The reasons for this vary. In some cases, the magical energy of the area has simply been used up. In other cases, by terrible accident or divine intervention, these locations are stripped of their energy for a questionable length of time.
In the same way, by some of the same forces that create dead magic zones, wild magic zones are brought into existence. In these places, magical energy is in a constant state of flux. In most cases, this simply means that every arcane spell cast causes a wild surge, but other, less predictable effects have been known to occur. Some report that the wildlife of the area was given sentience or that one could only move if walking backwards.

Wild Surges.
Unless the caster is in some type of wild magic zone, a Wild Magic Point (WMP) must be expended to induce a wild surge. In such a scenario, an otherwise streamlined and safe spell is pushed to its breaking point, sometimes decreasing, but oftentimes increasing the effectiveness of the spell.
The mechanic is as such: When a spellcaster induces a wild surge, the corresponding player rolls 4d6, drops the lowest, and compares his roll to ‘Table 1-1: Ability Modifiers’ in the Player's Handbook. The result is known as the Surge Modifier. The surge modifier is applied to the caster level of the spell. The caster level can never be modified below 1. If a spell can no longer reach its target, the spell instead targets the closest spot it can along the imaginary line between the caster and the target. If the Surge Modifier is an even number or 0, a Greater Surge occurs.

Greater Surges.
Pushing magical essence in such a manner sometimes causes the space and time around the caster to change in unpredictable ways. We call this a Greater Surge.
The mechanic is as such: The caster may roll a Willpower saving throw (DC 15+spell level) to prevent the Greater Surge, or may voluntarily fail. If he succeeds, the fabric of existence remains unaltered. If he fails his saving throw, the player must roll a 1d% and compare the results to the Greater Surge chart (below) to see what happens. Use the caster level modified by the Surge Modifier for any effects which depend on caster level.
DM’s are encouraged to look over the Greater Surge chart and change any lines that do not fit his campaign style. What one might do is create a different chart for each plane (some being wilder than others) or planar group. Perhaps he instead slowly, over the course of the campaign, changes lines and rearranges others. Or better, he replaces the lines that the resident wild mage hits, ensuring that no wild effect is ever repeated.

Wild Mages.
Wild Mages are those individuals willing to take the risks required to harness the illusive arcane energy which we still known so little about. However, not all ‘Wild Mages’ take their studies in Wild Theory as far as others. Those who do dedicate themselves to the field often take their research in very different directions.
To be more specific, wild magic theory research branches out in a tree of feats (as shown below). A wild mage may choose only to dabble in wild magic, climbing the tree only part way, while another might seek better understanding, giving up feats otherwise used for item creation or metamagic in the name of progress. A minor prestige class is offered below (at the DM’s option), for those who want to more seriously apply themselves to the field.
DM’s are once again strongly encouraged to add to the Wild Magic Theory tree or to use it as the basis for other types of magical specialization in his campaign. The arcane casters on the Beastlands might have developed some theories on fusing arcane energy with nature spirits and some on the Outlands might be studying that planes ancient Mirror Magic. Doing so would allow caster’s distinction, allowing some to focus on one type of magic theory or dabble in a few.

Feats.
Advanced Wild Magic Theory [Wild Magic]
You are an expert in wild magic and are able to wield it much more frequently.
Prerequisite: Iron Will, Wild Magic Theory, Potent Surge, Powerful Surge
Benefit: You now have 2/3rds more WMPs, rounded down. This feat still counts as a wild magic feat for purposes of establishing a WMP pool. Thus, if a character has all nine wild magic feats listed here, including this one, then he would have 15 WMPs.

Control Greater Surge [Wild Magic]
You studies allow not only give you control over magical energies, but over randomness itself.
Prerequisite: Iron Will, Wild Magic Theory, Potent Surge, Force Greater Surge
Benefit: When you roll a Greater Wild Surge, you may alter the result by one number up or down. For every WMP you dedicate to the cause, you can alter the result by one additional number up or down.

Deaden Magic Zone [Wild Magic]
You learned so much about repressing magic that you may deaden magic in an area for a limited amount of time.
Prerequisite: Iron Will, Wild Magic Theory, Repress Greater Surge, Wild Counterspell
Benefit: You may create a 30-foot radius dead magic zone, centered on an area, an object, or the caster. The area stays deadened for 10 minutes per WMP spent. No magical effect or spell may be initiated within the spell, nor can any magical effect or spell target anything within the area. All magical items cease to function. All magic is dead.

Force Greater Surge [Wild Magic]
You can cause chaos where there is none.
Prerequisite: Iron Will, Wild Magic Theory, Potent Surge
Benefit: You can opt to cause a Greater Wild Surge even when you roll an odd Surge Modifier.

Potent Surge [Wild Magic]
You can eliminate some of the negative effects of wild surges.
Prerequisite: Iron Will, Wild Magic Theory
Benefit: You gain a +1 bonus to your Surge Modifier

Powerful Surge [Wild Magic]
You almost completely eliminate the negative effects of wild surges.
Prerequisite: Iron Will, Wild Magic Theory, Potent Surge
Benefit: You gain a +2 bonus to your Surge Modifier. This bonus does not stack with the bonus from Potent Surge.

Repress Greater Surge [Wild Magic]
You’ve learned to repress some of chaotic aspects of wild magic.
Prerequisites: Iron Will, Wild Magic Theory
Benefit: You may spend one WMP to keep a Greater Wild Surge from occurring.

Wild Counterspell [Wild Magic]
You have learned to mutate spell energy in order to counter aggressive spells.
Prerequisite: Iron Will, Wild Magic Theory
Benefit: You may counter a spell being cast with any spell of one or more levels higher than the target spell.

Wild Magic Theory [Wild Magic]
Your studies in the field allow you to cause wild surges in your arcane spells.
Prerequisite: Iron Will
Benefit: You now have an amount of Wild Magic Points (WMP) equal to the number of Wild Magic feats you possess, counting this one. While casting an arcane spell, you may expend one WMP to cause a wild surge.
Special: Any person with this feat may accept a -2 non-magical penalty to their Wisdom score to cause a Wild Surge without expending a WMP. These penalties stack and is recovered at the standard rate of 1 point per day.
As a character’s wisdom score decreases, he finds it harder to make logical decisions and cannot stay focused on anything for too long. He begins to have strange emotional sensations that he cannot explain and does not react to normal stimuli in a consistent manner. He might hallucinate. He might loose his sense of space and time. If a character’s Wisdom score ever drops to below 1, he falls unconscious and is trapped within vivid nightmares until he recovers.

Class Features:
Weapon and Armor: Wild mages gain no proficiency with any weapons, armor, or shields.
Spellcasting: A wild mage continues training in arcane magic. Thus, when a new wild mage level is gained, the character gains new spells known and spells per day as if he had also gained a level in an arcane spellcasting class he belonged to before he added the prestige class. He does not, however, gain any other benefit a character of that class would have gained (such as metamagic or item creation feats). This essentially means that he adds the level of wild mage to the level of some other arcane spellcasting class the character has, then determines spells per day and caster level accordingly.
Wild Magic Skill: At 1st level, the wild mage gains a +2 bonus to Spellcraft checks regarding known wild magic effects (including, if a wizard, checks made to inscribe a wild spell into a spell book).
