heavy quartz orb duration and magic item use

[AestheticDeath]

What is the base duration on the heavy quartz orbs?

Does magic item use increase the duration?

I do believe it's five minutes on the dot. I calculated it for Brian and PSInet 2 -- I am also fully singled in MIU, and noted no increase in duration as opposed to my other characters.
