      Copied from the Upgrades page:

      Fatal Upgrades
      Upgrade weapons with the Fatal upgrade path from +1 to a max level of +5. This upgrade path requires the Marrowstone. The effect of the Marrowstone applied to weapons such as the Dagger, Estoc, and Rapier grants a Critical damage bonus towards backstabs/ripostes. But it also lowers the base damage of the weapon.
