Some spells and other effects require Concentration to remain active, as specified in their descriptions. If the effect's creator loses Concentration, the effect ends. If the effect has a maximum duration, the effect's description specifies how long the creator can concentrate on it: up to 1 minute, 1 hour, or some other duration. The creator can end Concentration at any time (no action required). The following factors break Concentration.
