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. Does Hard to Kill reduce the damage taken for the purposes of irreducible damage?
A. No. Hard to Kill prevents a model’s Health from being reduced and does not reduce damage.
