A '''Signature Spell''' is usually a low-level skill from which the [[Wizard]] reduces the cost of skill that requires no [[Arcane Power]] with 1 each time he or she levels-upto cast. It is most likely that these spells are known by all users of magic and are learn by apprentices.

Signature Spells were previously called Academic Spells. Before becoming completely free to cast, their [[Arcane Power]] cost was reduced by 1 with each time the [[Wizard]] leveled-up. Also, the [[Obsidian]] rune effect of [[Energy Twister]] requires one of the Signature Spells in order to release all Wind Charges.
