Magic reagent

Magic reagents are items used by witches to cast spells. Sims can obtain them in two ways:
 * 1) Craft them with a cauldron.
 * 2) Buy from the high witch with the same alignment as the Sim's.

List of reagents

 * Dragon Scales - Scales given from an Elder Dragon. (neutral)
 * Mystic Dust - Mystic Stone turned to dust. (neutral)
 * Crystalized Moonbeams - A moonbeam turned perfectly into stone. (good)
 * Essence of Light - The essence of a star in a vile. (good)
 * Viper Essence - Essence taken from a Viper. (evil)
 * Eye of Newt - Eyes take from a baby Newt. (evil)

Casting Spell without reagents.
There is a mod in Mod the Sims that make spells castable without reagends.

In other words no reagends needed for spells.
