Grade 3 Skybuilders' Umbral Magma Shard

Though the name may seem at first to be an oxymoron, each fragment actually contains magma in liquid form beneath a thin crust. Anyone foolish enough to put one of these shards in their back pocket before sitting down will cause a hole to be burned not only in their breeches, but also the chair on which they sat. Can only be gathered during an umbral flare. Used in expert crafting recipes.
