Default Blueprints

While not necessarily just for glasses, the glassblower is good for windows and any other form of glass object.  They can make the following at the start:

  • Glasses
  • Simple windows
  • Vials
  • Flasks

Skill Usage

  • Arcana, History: Your knowledge of glassmaking techniques aids you when you examine glass objects, such as potion bottles or glass items found in a treasure hoard. For instance, you can study how a glass potion bottle has been changed by its contents to help determine a potion’s effects. (A potion might leave behind a residue, deform the glass, or stain it.)
  • Investigation: When you study an area, your knowledge can aid you if the clues include broken glass or glass objects.
  • Identify Weakness: With 1 minute of study, you can identify the weak points in a glass object. Any damage dealt to the object by striking a weak spot is doubled.
