Ponderous Spellcaster

Your spells take additional time to cast.
Prerequisite: Ability to cast spells.
Effect: The casting time of all your spells are doubled. Spells that normally require a single action to cast require a full-round action to cast instead. Spells that normally require a free action to cast now require a standard action to cast instead.
Suggested Class/Race: Cleric
