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).


  • In real life, amylase is an enzyme found in saliva 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]
