So as well all know, Runes of warding states that all enemy psychic tests must be rolled on 3d6, suffering a perils of the warp on a result of 12 or higher. However, we also know that Perils of the warp normally occurs on a roll of 2 or 12 on 2d6. Does this mean that if, during a psychic check while under the influence of runes of warding, a psyker rolls two 1's in the 3d6 do they still take perils of the warp?

It's an odd discussion Splug and myself were kind of involved in more than once on occasion and I'd like to see what everyone else thinks.
