When you are in positive credit with the magical bank, the institute of karma, we say you are "charmed." You become a vessel of good luck, you lead a charmed existence and everything that can go right will. When you charm a person, you become a form of medication for them, curing, healing, with only the presence of your words.
Spells revolve around spellings to weave their "magical" effects, being charmed is a blessing from the universe, a reward for being an agent of good magic.
When you achieve the status of angel warrior you are armed with charms, you see harm and cure it with words, with spells, and the universe coordinates with you to bring maximum good results.
