Awesome thanks for the quick answers.

Quick question: when reading the sweeping strike trigger on Euripides it reads " When resolving, the target takes + blast damage" Is this trigger adding a blast marker to the damage spread or is the target taking extra damage as if it had been hit by a blast marker? And if it's the latter option what damage is taken on a weak flip as there's no lower damage stat than weak? Thanks.
