shadow in the warp vs Eldrad?

[The Plumber]

Does anybody know how this works? It makes my head hurt when I think about it:confused:

Well, a comparable situation is addressed in the Eldar FAQ about Runes of Witnessing vs Runes of Warding. If you were to follow that precedent, you would roll 3d6 and use the lowest for purposes of passing the test, but look at the 3d6 for the purposes of any perils. Otherwise, a straightforward compromise would be to assume the two abilities negate each other and roll a straight 2d6.

Keep Eldrad in a transport and ignore all SitW effects ;)

Eldar FAQ

Q. How do the Runes of Witnessing work when facing
a Hive Tyrant with Shadow in the Warp?
A. The Runes neutralize the effect of the Shadow in the
Warp for that Farseer, so the Farseer will take Psychic
tests using 2D6, as normal.
