Re: Does Blade Shield proc Rift orbs?
Yes, I can guarantee you that if you make a "Rift" and put it on a 'Sin, Blade Shield WILL trigger off Frozen Orbs.
None the less, it would still be a pretty hard to do, IMO. Riftdins work because they have Conviction. Now, assuming you have a mercenary with "Infinity", then, other the other issue I see is low trigger frequency. You're going to need some pretty wicked AR sources to get Blade Shield to fire off a Frozen Orb, and not only that, FO only triggers 16% of the time.
