Dread Scythe

The arcane damage is not dependent on the attack hitting.

The defending player chooses if they are taking the arcane damage first before defending the attack.

Both the attack and the arcane damage count as damage by Dread Scythe and either would cause the hero dealt damage to not gain during their next action phase.

If a hero dealt damage by Dread Scythe would gain during their next action phase they instead gain 0. (They may still play the card or activate the ability that would gain )
