So, say my Rune Priest casts Tempest's Wrath. And let's say a fast skimmer (take your pick which kind) attempts to turbo boost away, takes a dangerous terrain test due to my psychic power and fails it PRIOR to actually moving.
Is the vehicle immobilized and thus destroyed because it was ABOUT to turbo-boost? Or would it only become relevant after the vehicle moved?
Interesting question here with no clear answer in the rulebook. All it says is that skimmers take DT tests and all it says about dangerous terrain tests is that you take the test for any model that "enters , exits or moves through" terrain it never says WHEN in the movement phase you have to take the test.
Any ideas? Am I missing something very simple?
