We know that casting a spell often requires verbal and/or somatic components. Verbal and somatic components are clearly defined game concepts, but on discharging a spell, all I have is this:
Occasionally a spells lasts for a set duration or until triggered or discharged.
Sometimes, the discharging requirement is obvious, such as with True Strike. But what about those spells that require specific activation to discharge? How does the caster do that?
My specific situation: The party Wizard has been paralyzed. Can she take the swift action to discharge her Heart of Water spell (Complete Mage) while paralyzed?
