The ENCHANTER is *NOT* the 'Enchanter Spec. Mage' from the PH2.  In the
system of magic I have put forth, 'Enchantment' encompasses spells that
temporarily or permanently 'embed' magical power within objects or
creatures, often using it to transform them into something else (e.g.,
polymorph, metamorphose liquids, fabricate) or to imbue them with some
supranormal ability (e.g., fly, strength, Tenser's transformation).  This
also includes spells that place magical powers within objects (e.g.,
alarm, explosive runes, glassee, phase door, symbol) and 'alchemical'
spells that involve poison and acid.  Thus, the Realm of Magic called
'Enchantment' is similar in many ways to the 'Alteration' school, but with
many additional spells culled particularly from Enchantment/Charm (i.e.,
the object-affecting spells, not the mental attacks), Alchemy, and
Artifice.  They love studying in their laboratories and remain somewhat
tied to them.

Enchanters are skilled at pulling in magical energy from their environment
and at storing magical energy, both in the form of stored spells ready for
instant use and in the creation of 'quasimagical' items akin to standard
magical items but only of temporary use.  They also are sensitized to the
natural ebb and flow of magical energy in the world.  Enchanters *can* be
very effective in combat, but their best skills rest in support roles and
overcoming obstacles.

The Enchanter kits are:

ALCHEMIST - expert at ID'ing and creating potions, poisons, and misc.
chemicals and using magical power through their alchemical arts.  They are
studious and knowledgeable but highly specialized and not as good at
non-Alchemical magical tasks as other Enchanters or as in tune with the
magical environment.

ARTIFICER - akin to an Alchemist, but specializing more in the realm of
permanent and temporary magical item creation and spell storage.  They are
also highly lab-oriented and less in tune with the general environment.

NATURALIST - the opposite number in many ways of the Alchemist and
Artificer, Naturalists can sense and channel magical energy inherent in 
nature and especially devote their focus to the study of animals and
plants, with great mundane and magical skill in this area (including the
ability to calm animals (and plant creatures!) as a ranger can).  They can
even use certain priest spells in their area, but are not as good as most
forms of wizardry as other Enchanters.

TRANSMUTER - something of a middle ground subspecialist, Transmuters focus
on magic that effects a 'state change'--a real, tangible, substantial
change to the form, figure, or substance of a creature or object rather
than just imbuing a magical effect.  They do like to experiment a bit, but
they eschew lab work in favor of 'field work' as the best place to really
test the limits of magic and how it can be used to 'make its mark' on the
world.
