When you begin your ValdaSpire24Extras, you can choose to replace the Graceful Dodge benefit with Shadowdance.
Shadowdance
You create a shadowy duplicate of yourself which dances alongside you in your space. When a creature hits you with an attack roll while your duplicate remains, roll your Dance Die. If it rolls a 3 or higher, the duplicate is hit instead of you and the duplicate is destroyed. A creature is unaffected by this feature if it has the Blinded condition, Blindsight, or Truesight.
The duplicate vanishes when this ValdaSpire24Extras is no longer active. Your duplicate reappears at the start of each of your turns.
