Enchantment is the process of imbuing an object - or person - with magical power. Some enchantments are temporary, while others can offer permanent benefits. Enchanting can be difficult to learn, but it is one of the most potentially lucrative forms of magic to study. It is one of the studies of magic that is least likely to culminate destruction.
Disenchanting is the process of dispelling or removing magic. The dispel magic spell is among the most important in a mage's arsenal, as it can potentially reverse the catastrophic effects of a misfired spell. It is also possible to permanently disenchant a magical item. This produces a unique form of crystallized mana that can be used in the process of imbuing another item with magical abilities. While this can get expensive, it is often one of the best ways for a young mage to study the enchanting process.
