When your character pulls back a weapon when attacking, hold A. Release A after the attack does damage.
Once you beat Crypt Ruins, you have access to the Bandit's Hideout. On the 3rd floor, collect the Broken Telescope in the northeast room. Beat Carcano and return to the Blaze Ruins. Collect the Cloudy Lens at the exit of the 4th floor(Maybe you've collected it already). Take it to the Appraisal Clerk, Keeno, and ask him to have the items 'Assembled'. You'll get 4,000 dinale.
