Warhammer 40K Tabletop XIV: "Pray for 6's!"

[Etcetera]

Pretty sure that's what happened, yeah. (Except that as I outlined above, it's exactly 50% chance of failure for Ld 10) I'm pretty sure the question was about Shadow in the Warp, though, since the topic of discussion was the value and reliability of GK force weapons, especially against 'nids.

Well, we now have the numbers for both. And in my opinion, they underline just how useful runes of warding are.
