6th-level transmutation (Sorcerer,Wizard)


  • Casting Time: 1 action
  • Range: Touch
  • Components: V, S, M (an ointment made of 50 gp of diamond dust for each 10 cubic feet of material)
  • Duration: Permanent

This spell permanently reinforces the strength and durability of materials. Paper is much harder to tear, wood is more durable, and glass is harder to break. You can touch and affect up to 50 cubic feet of material each time you cast this spell. The material becomes resilient if it was fragile, and its AC is increased by 4. If a material is already resilient, it doubles in hit points. For example, if you touch a resilient section of wooden wall that has 50 hit points, its AC would improve from 15 to 19, and it would have 100 hit points.
