Ring of Strength: It is a transparent, slightly whitish ring that Yusuke created by customizing a shouka. The ring dramatically increases its wearer’s strength. Bahana’s Bow: It was a common, yet sturdily made wooden bow. As the rarity level of the bow was low, the customization Yusuke could perform on it was also limited. As he could not enchant ease of use effects like he did for Shinha’s great sword, he had to settle with an accuracy increasing buff.
