Crystal Shard

Crystal Shards are a common Hardmode crafting material found in the Underground Hallow, where they naturally grow on any side of Pearlstone Blocks and Pink Ice Blocks. Due to their constant regrowth, they can be farmed. Crystal Shards emit a small glow, similar to Demonite Ore and Crimtane Ore. They do not spread the Hallow.

On the, Crystal Shards are available pre-Hardmode, as they are always dropped by Arch Demons in stacks of 3–4.

Crystal Shards are also placeable in nearly any position (on walls, floors, and ceilings), though they are often not luminous enough to replace other light sources, and placement has no other functional effect. Although natural Crystal Shards can only grow on Pearlstone and Pink Ice, once harvested, they can be placed anywhere.

Crafting all items, including only one color of Phasesaber (excluding consumables), requires a total of 115 Crystal Shards. Add 250 for all the other Phasesaber colors.

Tips

 * Crystal Shards have an unusually high sell value relative to their commonness, so farming them can be one of the most effective ways of making money throughout Hardmode. A full stack is worth.
 * With Pixie Dust (otherwise worth less than /stack) available, crafting and selling Greater Healing Potions multiplies the payoff on a few crystals to /crystal. The Alchemy Table's bonus raises that further, to about /crystal.  A stack of 99 Pixie Dust with 33 crystals (and 100 sand for bottles), crafted at the Alchemy Table, yields about, a % increase over selling the ingredients.
 * Crystal Shards can be farmed with an appropriate layout. See Guide:Farming Resources for details.
 * Since they emit a glow, getting rid of light sources makes it easier to spot them.
