Agent Watch
Agent Watch scales weapon damage with the Keys you currently carry. The individual revision says Keys already held when you pick it up also count.

I would hoard a key through a combat room and spend it after the clear. The table ties the buff to holding keys, not to a permanent upgrade.
Effect
The tooltip describes collecting and spending Keys, but revision 7444 explicitly clarifies that the current held count determines the bonus. You do not need to collect the existing Keys again after taking the Watch. Spending a Key lowers the contributing balance; no damage percentage per Key is established.
