Amylase crystal detail

Amylase crystals are a herblore secondary used in the creation of stamina potions. A player can mix amylase crystals with a Super energy potion at 77 Herblore to make a stamina potion. One amylase crystal creates a single dose of stamina potion from a Super energy(1), and as such, four amylase crystals are required to create a stamina potion(4) from a Super energy(4). One amylase pack contains 100 amylase crystals, costing 10 marks of grace, and can create 25 Stamina potion(4). Amylase crystals can be bought from Grace found in the Rogues' Den.


  • In real life, amylase is an enzyme secreted by salivary and pancreatic glands used to break down starches.
  • Upon release amylase crystals were not tradeable. However, Mod Ash announced this was an error as Mod John C had already written in the developer blog that they would be in fact tradeable[1] and announced they would be made so in the update the week after their release.[2]
