Drinking a potion or using an oil on an item of gear is a standard action. The potion or oil takes effect immediately.
Activating a command word magic item is a standard action and does not provoke attacks of opportunity.
Unless stated otherwise, activating a use-activated magic item is either a standard action or not an action at all and does not provoke attacks of opportunity, unless the use involves performing an action that provokes an attack of opportunity in itself.
So if I drinka potion of Lesser Restoration, its only a standard action to get the restoration effect, but if I cast it from preparation, its three rounds?
Am I missing something?
Scrolls and wands both state that they take a standard action unless the spell takes longer than that to cast, in which case you use the actual casting time.
WIth the magic creation rules, the PCs have built a belt that the monk uses to Enlarge Person on himself. SHould that take only a standard action, or a 1 round?
