So, the Grav-Weapon Conundrum

[jaqenhgar]

Personally, I think it loses only 2HP since the first hit means immobilised and -1 hull point, the second hit it loses a hull point and is already immobilised so that has no effect. I understand an immobilised result usually also results in a hull pt loss and hence where the 3 hp is coming from, but I think it's trying to specifically state that each 6 causes 1hp loss.

Regarding cover, not really sure, it is a hit and it doesn't specify ignores cover which a lot of things do, but it wouldn't be unreasonable for a grav weapon to ignore cover so could go either way with this one.

Why can't GW write rules properly?!
