Alchemy

Alchemy is the art of creating and fusing Magicite, alchemical items,
and potions.  Alchemy uses Craft (Alchemy) and Knowledge (Arcana) for
its operation.  Fusing magicite is a tricky business, and can take
more mundane, but expensive, components than just the magicite to be
fused.  For more information on spell recipies, consult the Magic
file in the Rules section.

To make spell magicite, you must have 1/2 the market price of the
spell in materials, and the required magicite to fuse together.  The
market price of most spells is the spell level squared x 1000 gil.
Much Magicite, when used, 'attunes' to the character that uses it
first.  In these cases, the magicite cannot be used by anyone *but*
that person.

The craft DC for making most spell magicite is equal to 20 + spell
level x 2.

Creating alchemical items operates just like it did previously in 
d20.  Consult the 3.5 SRD skill section on Alchemy and the Arms and
Equipment Guide for more information on this craft.

Finally, Alchemy can be used to create potions.  This operates just as
the Brew Potion feat, except that instead of using experience, you use
a craft check.  If you fail the check, you botched and lost all
components used to craft the potion.  DCs will be determined by me on
a case-by-case basis, but I will try to be consistant.
