Playing Sentinel Tactics, The Wraith is attacking Baron Blade with a 4-die attack, and aiming. One of the attacks is a 6, so she ends up with four 6s.
Baron Blade rolls his three defense dice -- All 6s. I stare at it in disbelief. I mean, through all the years of rolling up D&D characters, in particular, and all sorts of other games, I don't know if I've ever seen that -- a natural 18.
Then I notice that Blade has out his power that allows him another defense die and roll it. Another six.
Then I notice that The Wraith has out her power that allows her to reroll a defender's defense die. Another six.
A 4-die, aimed attack resulting in four sixes, plus the ability to reroll a defense die. All blocked.
It's good for you, because you get to share a pretty cool story and bask in the jealousy of your peers. For the heroes and/or villains? That depends on which side you were rooting for at that moment.
