I played Forbidden Lands and loved everything, except that it uses dice pool.

It had the perfect level of crunch and lethality in combat. I loved the critical injury system.

So im basically looking for Forbidden Lands but not dice pool.
And Dragonbane seems kiiinda similar?
But deathsaves and larger hp pools kinda bums me out.

So, need advice on DB:

Do you think the game supports a mature and dark story?
How lethal is the combat?
Can you easily modify the system to be like I want it, without breaking it, or is it better to stay with Forbidden Lands?
