Trooper A is immobilized-1 state in ITS11 “Hunting Part”. Trooper A declares Reset. Enemy trooper declares BS attack ARO with his stun pistol. Both troopers pass their skills rolls. Trooper A fails the BTS checks, which causes him to fall in immobilized-1 state twice. Q1: Is trooper A in immobilized-1 state after the order? Q2: Is immobilized-1 state stackable? If model trooper suffers multiple Immobilized-1 states, does he need to declare multiple Resets to get rid of them?
Using doctors healing unconscious models while under fire as precedent, I would say that you clear the previous IMM state and then apply the new one, yielding no net change.
States, by default, can't be possessed multiple times. You can't be IMM-1 multiple times any more than you can be Prone multiple times. That's part of the reason why doctors healing unconscious models while under fire is a useful precedent. Rather than try to figure out an ordering, and whether the trooper dies temporarily, the two mutually opposing effects simply cancel each other out and you're where you started at.
There was thread earlier here about Antipode pack freeing their buddy with power of friendship*. If I remember correctly, the consensus was that trooper can suffer multiple Immobilized-2 states at the same time. Why this situation would be different? But let’s assume that this is different, because everyone hates Antipode rules. A model can only get one immobilized-1 state regardless of number of different sources. The immobilized-1 state can’t get worse even if Reset failed and Stun pistol ARO critted multiple times. So it’s not the same as unconscious getting shot while being treated by a doctor. * Antipode pack can self generate and heal Immobilize-2 . Certain non-lethal weapons trigger the same state.
Antipodes are weird and need to be dealt with specifically, this question is general as were the previous answers. God I hope Antipodes dies as a rule in N4.
That was being IMM'd via two different methods which have two different cancellation conditions. It's not really comparable, and I don't think changes the answer to this question.
