Anyone have the old WD 255? I don't know what the special rules are for the terrain, and I tried contacting GW but they weren't able to provide a ruling on the subject either. Alan and I will need those rules by Monday, or a ruling from Chase on the subject.
I can't find a thing, there's nothing in the US WD 255 to cover this. So I went looking for something fluffy,
I'll propose this.
*Earthshock: When the final position of the tremor cannon blast is
determined, place a suitable marker under the hole and roll 4D6. This is
the size of the shockwave zone generated by the shot. The shockwave
lasts until the start of the Banehammer’s next turn. Any units moving
through the shockwave zone will do so as if they were moving through
difficult terrain. Any units moving through difficult terrain in the
shockwave zone will roll 1D6 less than normal to determine their
maximum movement. Vehicles treat the shockwave zone as dangerous
terrain – including skimmers (their motive systems are particularly
vulnerable to boulders and rock shards being hurled into the sky).
Its from the Tremor cannon on a Bane Hammer. I'd say we just roll a D3 for each every turn, there will be D6+1 of these so if we roll high that could get ugly very quickly.
Just a thought.
Cheers,
Alan
