Shards refer to the shortened term, Obsidian Shards, which is the second key
ingredient in making the Fissure of Woe armor. Although Shards are not as
expensive as Globs of Ectoplasm, they are still in-demand by many Fissure of
Woe armor seekers. Obsidian Shards only drop in the Fissure of Woe, the place
where everyone goes to make the Fissure of Woe armor.

EXAMPLE: I only need 15 Obsidian Shards to complete the Fissure armor set.
