For me, the magic sauce of DB was Willpower Points and Attributes as they set up Skill levels and bonus damage.
For my second DB campaign, I set up an attribute array to ensure the highest attribute was 15, which gets d4 bonus damage and a trained skill of 12, which is a 60%. Definitely gave the game a gritty genre.
This forced my traditional min/maxer into engaging in the environment and other players to look for boons or create banes. It's been the first time he's ever done that.
It was also interesting in that while he admitted getting more WP from Heroic Abilities was the best move, he kept getting tempted to pick other HAs that looked sexier than just "get 2 more WP."
