The Chosen has a hunter move called Resilience: You heal faster than normal people. Any time your harm gets healed, heal an extra point. Additionally, your wounds count as 1-harm less for the purpose of the Keeper's harm moves.

Can someone please explain what "your wounds count as a 1-harm less for the purpose of the Keeper's harm moves."? Is that like +1 armour? Does Keeper harm consist of "environmental harm" as well as Monster harm? -_- so confusede
