How to get it
- Defeat Rocket Grunts, Leaders, or Giovanni, or complete eligible Shadow Raids.
- Shard collection is restricted when you are already holding the normal maximum of Purified Gems.
How to use it
- Collect four and allow the Shard Refiner to combine them automatically.
- Use the resulting Gem during an eligible enraged Shadow Raid.
Worth knowing
The usual Rocket rewards are one shard from a Grunt, three from a Leader, and four from Giovanni.
