And, "You can interact with one object or feature of the environment for free, during either your move or action...Some magic items and other special objects always require an action to use, as stated in their descriptions."
The default action for interacting with an item separate from another type of action is Utilize, which is an action in itself. "You normally interact with an object while doing something else, such as when you draw a sword as part of the
Attack action. When an object requires an action for its use, you take the Utilize action."
Finally Fast Hands, "
Use an Object. Take the
Utilize action, or take the
Magic action to use a magic item that requires that action."
So if it's not included as part of the Magic Action rule for activation, where are you getting it? And if it is part of the Magic action, then how is it not a magic item which requires the magic action?
