Tried using the mining drill on crystal islands but not getting any shards

Mantis+ hatchet= good shard farm

On crystal isles DO NOT USE the mineing drill for this resorce it dosent work ankys are top for this

Use the mining drill in the volcano on genesis on red crystals and then take the shards to a tek replicator to make loads of element

Useing a hachet is better for more shards outcome, because the shard is substituted by rocks

Crystal isles....crafted hatchet and mantis

Go on eldritch island in CrystalIsles this is a little bit dangerous but you gonna have a lot of element shard.

If you have one, a Phoenix can be used to harvest the crystals at the Eldrich Isles using the tertiary attack. There is a glitch however where at a specific spot, you will teleport into a bubble full of jellies not far from where you exit, the Phoenix will spawn on top of you however.

Over on crystal isles there's a snow crystal biome with light ;kue crystals. These drop straight element shards.

Not sure who rates these but the mantis with good pick on lunar is far better then an anky.
