Empower

Empower is an Activated Ability keyword, normally present on permanents and legends.

It is formatted as "Empower [Cost]" and is functionally short for "[Cost]: Empower this. Play only if not Empowered."

Empower has a cost to activate and Empowers the source of the ability when the cost is paid. The source game object is not a target of the Empower ability.

Empower costs may include both resource costs and non-resource costs.

When the Empower action completes from this keyword, the source permanent or legend becomes Empowered. This is an event other Game Effects and Triggered Abilities can reference.

Multiple instances of Empower are equivalent to multiple activated abilities and can each be activated separately by paying the corresponding costs.
