A bit of a tactics with a dash rules query.

Space Wolf Rune Priests have a couple of cool "defensive" powers namely Storm Caller and Tempests Wrath.
Now I've been thinking, if you put a Master of Runes with said powers in a Land Raider you end up with quite a large bubble in which landing Jump Infantry, Jetbikes and Skimmers have to take a difficult and dangerous test.
If I remember the outcome of the landing on wrecked vehicles debate correctly, then jumpers and jetbikers will have to take two dangerous terrain tests each, no?
Combine this with a raider with a 5+ Cover Sv, times two, add some troops to each raider so they can take objectives and you get monster area denial against anything airborne.
Let’s see rubber hawks get though that.

So, what do you all think?

Why 2 dangerous terrain tests?

Wrath makes everything a wreck.
Wreck is difficult and dangerous
Previous arguments have said that
Bikes treat difficult as dangerous
Therefore moving through such things is moving through dangerous and dangerous.

I can't remember the outcomes.. but in 5th ed p14 its one test per model per "its move" so on a move they'd each take a test, in run, they'd each take a test assualting they'd each take a test.. but you wouldn't take 2 during any phase.
I think thats right anyway

I see, I was under the impression that the outcome was that, they had to take one danger test for dangerous and one danger test for difficult, so two per wreck. However if that is not the case, so be it.

EDIT:

Just had a read of the rulebook, here's what I found:
Deep Strikers will only take one test, as they treat difficult terrain as dangerous, and you only take one test for any number of dangerous terrains.
Skimmers are the same, as landing in difficult or dangerous causes one test.
Jump Infantry (both types) and Jetbikes however, will take one test for moving into dangerous terrain, and as ending a move in difficult terrain makes them take a dangerous terrain test, they will take two test in total.

Hope that makes sense.

So now we have the concept of "more dangerous" terrain
