uncancellable and cancellable damage on the same target

By hogilogic, in Warhammer Invasion Rules Questions

imagine player A attacked with a bloodthirster and an ironclaws horde and blayer B defended with 2 ironbreakers of ankhor with x=3 (-> toughness 3).

the bloodthirster would deal 5 uncancellable damage (right? the text says "damage cannot be cancelled."), while the horde would deal 4 damage.

the first 3 uncancellable damage could kill one ironbreakers (because they have 3 hp), right?

and the remaining 2 uncancellable damage would be assigned and applied to the second ironbreakers (since it circumvents toughness), but A would have to use all 4 remaining cancellable damage to kill it (because it has toughness=3 only 1 damage would come through, which would then suffice to kill it), right?

now imagine an effect that gave A's bloodthirster +1 axe, would this 6th axe also be uncancellable, i.e. would A be able to kill both ironbreakers with his bloodthirster's damage and the 4 damage from the horde come through?

sometimes i wish the damage tokens had two different sides, so that one could represent assigned and applied damage differently.

Bloodthirster makes ALL damage uncancellable, not only damage dealt by Bloodthirster.

wait, what?? does this mean, that ANY damage dealt while the bloodthirster's in play is uncancellable? great news, this makes my orc-chaos deck so much stronger :D

That is correct. Bloodthirster is a global effect.
