In the D3 demo, I've seen a few yellow orbs drop that produce a "Nephalem Glory" buff (that I've never seen in the PC version), but since I have no mouse, I cannot mouseover and figure out what the heck it does. The buff doesn't appear to do much, at least.
What does the buff do? Do they stack? Is there a cap? How long does it last? What are its drop conditions?

According to Blizzard:
So, it adds bonus damage plus an immediate burst damage and, as it stacks up to three times, it adds speed, chain damage and random burst damage, followed by burst damage when it runs out. It lasts 60 seconds by default, but all orb pickups will act in ways to extend this duration. It drops entirely randomly along with other globes when vanquishing an enemy.
