Byzrite

Byzrite is an beige, bone-like organic substance found in the hornlike protrusions on the bones of Avernic demons. While all Avernic races grow these protrusions, those of the Byzroth – particularly their skull crests - are both more prominent and more varied than those of the Alyaroth and Tsutsaroth; hence the substance is named them. The root material, where the protrusions attach to the bone, is the strongest and most sought-after.

Byzrite shards can be obtained through the Mining skill in various places throughout RuneScape by mining a Byzrite deposit. Shards can be mined with a Mining level of 85 or higher, and doing so grants N/A Mining experience. The shards can be smelted with one Alyarite geode, four pieces of Imcandite and one heap of Hellflux through the Smithing skill to form an Avernium bar, which can then be smithed into various  pieces of Avernic armour.
