Talismans are a special form of Charm that can trigger one or more additional effects if provided with extra Power by whoever is maintaining them. These effects are known as Activation Effects and occur whenever the Talisman is provided with additional Power equal to or greater than its minimum Activation Power. This Power is handled separately from the normal maintenance cost of the spell, and can come from a separate Channel. It may not exceed the Talisman's maximum Activation Power. Activation Effects are effectively Fleeting in duration and can be triggered at any time – allowing them to be combined with Reactions.
