  • Increase the bonus to attack and damage rolls to +2. In addition, targets damaged with this weapon take an additional 1d6 points of force damage.
  • Whenever you use your Cutting Words feature while wielding this blade, the target has disadvantage on their next saving throw.

Exalted. When a character exalts Mythcarver, apply the following changes to the item’s traits:

  • Increase the bonus to attack and damage rolls to +3.
  • You can spend an action to let the spirit of the sword overtake you momentarily. You make four melee attacks with this sword, then suffer one point of exhaustion. You cannot use this ability again until you finish a long rest.
