Mantle of the Protector (CoP) - duration

[Buba HoTep]

In champions of purity the magic item Mantle of the Protector has a duration of ten min. Can the user spread this duration out incrementally? It doesn't say once a day or anything to indicate otherwise but I does state the ally loses the benefit of his armour and shield for one minute.

At the start of each day, the owner of a mantle of the protector may spend 10 minutes attuning the mantle to his armor and shield. He may then lend his attuned mantle to an ally, who can activate it as an immediate action at any time to gain the owner's armor and shield bonus as well as any other special properties the armor may have for 10 minutes. When the mantle is activated this way, the owner's armor and shield go dormant, and he loses any benefits they may provide for 1 minute.

The way it's worded it sounds like once your ally activates it, it stays on for 10 min.

Also, the owner of the cloak loses the benefits of their armor/shield for 1 min, not the ally.

Yeah I was speaking in the first person so the ally was the person lending the armour in this case.
Interesting, but I'd like to see a version that could be incremental. Perhaps with another spell added and a cost increase.
