Q. Are two Abilities that are prefaced by the same text (before parenthesis) the same Ability?
A. No. Abilities such as Demise (Eternal) and Demise (Dead Horse) are two separate Abilities and can both affect a model at a single time. There are some effects that specify Demise Abilities, which affect all abilities prefaced by Demise.
Q. When a Shockwave or Pulse affects both friendly and enemy models at the same time, who chooses the order that models resolve the generated duel?
A. The model that generated the Shockwave or Pulse determines the order for all affected models. When a model is chosen to resolve a Shockwave, it resolves its duel and any subsequent damage completely (including any new generated effects, such as Pulses or effects that trigger when a model is killed) before the next model is chosen to resolve the Shockwave’s duel and damage. This may result in situations where a model is killed by an effect such as Demise (Explosive +3) before it resolves its Shockwave duel, in which case the duel generated by the Shockwave is ignored.
