Let me quote from the new Imperial Armour Apocalypse 2nd edition (emphasis mine):
pg. 128 wrote:If gargantuan creature is hit by a weapon that uses a blast master, the normal rules for determining if the creature is hit by the marter are not used(as the marker may be smaller than the creature's base, and so it could never score a direct hit) Instead the Gargantuan creature is automaticly hit if the hole in the center of the marker is over the gargantuan creatures base(or its body, if it does not have a base). If the hole is not over the base, but the rest of the blast marker covers part of it, the creature is hit on a 4+ as normal
What we can't seem to make sense is the two parts in bold that a) seems to imply that the whole base need to be covered by the blast marker and b) that if you are only touched by the marker it's a 4+ save. If I remember correctly this rule seems a lot like a 4th edition throwback, but I could be mistaken.
Anyways, just wanted to hear if anyone else had noticed this and perhaps had an explanation?
Cheers
