Wild Mage

"Your innate magic comes from the wild forces of chaos that underlie the order of creation. You might have endured exposure to some form of raw magic, perhaps through a planar portal leading to Limbo, the Elemental Planes, or the mysterious Far Realm. Perhaps you were blessed by a powerful fey creature or marked by a demon. Or your magic could be a fluke of your birth, with no apparent cause or reason. However it came to be, this chaotic magic churns within you, waiting for any outlet."

The wild magic

A wild mage knows fewer spells than a sorcerer, yet can create more spells then sorcerer. (Wildmage know only 23 spell + 5 SLA, but have 6 wildcast with "any" random spell, additional each spell has a chance to create bonus multiple effect.)

The randomness of wild magic doesn't mean you can create any spell from the level (that couldn't be handled in the game).

Each of the six wild magic abilities requires a list of usable spells. After all, who would want to teleport instead of a reinforcement before the end of the mission. Not to mention that there are protective spells that require an additional choice (e.g. Resist Energy).

It's probably easier for the system to list only offensive type spells. 

Possible (this can already be attributed to the nature of random magic):

• • • Wild mage create a touch range spell to a distant opponent (e.g. Ghoul Touch). 

    • Wild mage cast a spell that doesn't match the target type (e.g. Command Undead to an elf).

In such a case, the magic (and the required SP) will be used up without any effect. 

Of course, spells that are too special or strong, or it would simply be too difficult to build into the wild mage can also be removed from the lists.
