Buy RS3 Alchemical hydrix dust
Alchemical hydrix dust is a members-only item in RuneScape 3. It is the fine dust of an alchemical hydrix gem. Its main job is simple. One dust recharges an Essence of Finality amulet by 50 percent. It also works on the ornamental version of the amulet.
The Essence of Finality amulet is a top combat amulet. It gives a +56 bonus to all combat styles and a +7 prayer bonus. It can also store a weapon special attack. The amulet runs out of charge over time, so players need this dust to keep it working.
Players can make the dust by crushing an alchemical hydrix with a chisel. This needs level 90 Crafting and makes 10 dust per gem. It can also be made at an Inventor's workbench with level 117 Invention and level 90 Crafting. The dust drops from the Zanaris Market trinket stall at level 116 as well, but it is rare there.
The dust is tradeable and stackable, and it weighs nothing. Buying it saves time and skill requirements. It is a smart pick for anyone who uses an Essence of Finality amulet in tough fights.
