You have learned to manipulate the Tessen in new ways, using its pointed spokes as weapons and tossing it at your foes from a distance. You gain the following benefits.
Ability Score Improvement. Increase your Strength or Dexterity score by 1, to a maximum of 20.
Adaptability. For you, a Tessen has the Adaptable (Piercing) and Thrown (range 20/60) properties.
Projectile Deflection. While wielding a Tessen, you gain a special Reaction that you can take once during each round. This Reaction can only be used to attempt to deflect a projectile with the Tessen’s Special: Fan Shield property, and you can’t use it on the same turn that you take your normal Reaction.
