Freeclimber's Sidekick

You have mastered free-climbing and now open new opportunities to yourself. 

 You now have a base climbing speed, equal to Half your Movement, so long as you have a Piton Equipped.
 
 You now gain proficiency with the Piton as if it were a Dagger/Dart and can make Melee and Ranged Weapon attacks with them as such, their Damage Die is that of the same weapons(D4), and takes your dex modifier. 

 You may use Pitons as free-climbing assets without a rope. For every piton you set on the way up a scale, you may remove five feet of movement needed to descend the same trip.
