Q: What happens to an embarked Dreadnought that suffers an Immobilized result from the hit when the Stormraven it is embarked in Explodes? (p38)
A: It is Destroyed as it is unable to disembark.
Were people arguing this one, after it was answered in the Grey Knights codex? Probably. Thats it for Blood Angels.
Q: Does the Crucible of Malediction affect vehicles that are also psykers? (p60)
I had thought this one was already answered. Regardless, it is now.
Q: Does every psyker in a unit of psykers, which are in range of the Crucible of Malediction when it is opened, have to take a Leadership test? (p60)
A: Yes. The notable exceptions to this are units with the Brotherhood of Psykers special rule. These units just take a single test, and will loose a single model if failed.
This one is pretty much as written, but I have had to clarify this rule for people in the recent past.
That is pretty much it for the faq changes. I am glad GW is still working on the FAQs and willing to do even minor changes. Links can be found here
