User blog comment:AtheistUntoDeath/Which of these Champions Would win? Part 4/@comment-5035765-20140523035813

If Veeeektor could get a clear shot, his death reay would tear Ori some superfluous holes in her metal exterior.

HOWEVER, given their environment, if Orianna was able to distract him while the ball knocks Viktor into some of the machinery with the concussion pulse from Ori's Ultimate, it'd spell a messy end for our favourite Machine Herald (i'm imagining the place is somewhat like the droid factory from Star Wars Episode II from your description). Viktor doesn't have the same kind of displacement tech (at least in his kit) to take advantage of such environmental hazards.

So, unless Viktor gets a Death Ray shot in, Ori wins... but that's a big-ass but.
