Avernium

Avernium is an alloy created by the fusing of living Alyarite and Byzrite. It can be created at 85 Smithing skill by smelting an Alyarite geode, a Byzrite shard, four pieces of Imcandite and one heap of Hellflux in a Fume-hooded furnace granting N/A experience. Outside of Daemonheim, it is the highest level bar in the game.

At any anvil, players can smith Avernium bars into various Avernic weapons and armour, granting N/A Smithing experience per bar used. When smelted and smithed, a Avernium bar produces N/A Smithing experience in total.

Avernium is made by heat-fusing an Alyarite geode and Byzrite shards using Hellflux. The Hellflux mimics the composition of Avernic ichor, and is used to reinvigorate pieces of Alyarite before it is forged with Byzrite, and keeps it alive in the high temperature conditions of the forging process. The resulting metallic substance has colours encompassing a spectrum going from dark red, crossing through purple, to light blue.
