Thanks for the feedback! As for the Skill, it's not used through the menu. The skill should trigger automatically when interacting with breakable objects. The only breakable objects right now are cracked rocks. All chest should be accesible in one way or another. Knowing that, if you keep experiencing issues let me know.
Also, Psy-Launch should be greyed out too! So I'll be patching that as well in a future update.
