I just played artifact anarchy, my mage (forgot the name) with life saving block lost to punishing bolt by another mage attached with spark generator. I checked my mage facing the opponent and there is no mud on terrain. Is this a bug or suppose that way
Life saving block only counts the attack base damage, not buffs. If the base damage is not enough to kill you, it does not activate. The buffed damage can then kill you. See here for more information.
Can we get an update to the card text? I just got completely hosed by Totem Blast in the second fight of the last AotA adventure because it says, simply, "Only triggers if damage would kill you." Then it didn't trigger, and then damage killed me.
