Spell

A spell or incantation is a series of words that, when spoken, invoke some magical effect. Reciting a spell is commonly referred to as casting a spell or chanting. In order to be effective, spells must be performed by a magical being. To this end, a spell recited by a mortal will not work. Whilst spells require to be spoken they can also be performed non-verbally and can be channeled and used by powerful telepathic beings.

Spells that create negative magical effects, that harm others, are called curses. These spells are difficult and should not be taken lightly.

To reverse the effects of a spell, one can use a reversal spell.

Spell Casting
The ability to cast spells is called spell casting. It's a basic ability that all natural born witches possess (along with sensing and potion making). Some spells require more power and thus must be cast by one witch or multiple witches at once.

Serena Spellbook
Every Serena Witch traditionally write her spells into their Serena Spellbook, both for their own reference and to preserve them for posterity. Of course, spells are also collected in other books.

The Serena Spellbook that is considered to contain the most powerful spells is the family spellbook. With spells written by witches from the entire Serena Family line, it contains a plethora of spells, potions, and pages of every powerful Serena Witch. The page of the spellbook contained a "Witch Pregnancy", which describes what a Serena Witch goes through in her pregnancy.
