I ran into my first issue with most rolls succeed with a perk or complication, defenses. When the players roll their defenses I want 4 states, avoid with perk, avoid, take damage, or take double damage.
But every other roll in the system is succeed with a perk, succeed, succeed with a complication, and fail with a complication. How can I phrase "you succeeded in avoiding being hit, but you still took some damage, not as much as you could have taken, but still some."
