Witcher 3 Remastered Transmog: How to Change Armor Appearance by Unlocking Reforge

The Witcher 3: Wild Hunt Remastered adds an armor appearance transmog feature officially called Reforge, unlocked by completing the Master Armorers questline from the blacksmith at Crow's Perch, which is recommended for level 24 and requires defeating an Ice Troll and an Archgriffin. After completion, the new forgemaster Yoana lets you pick one piece of gear for its stats and another for its appearance, paying a small fee per altered piece, and Reforge can only be used by returning to Yoana.
