Crystal dust is a Herblore tertiary ingredient used for creating divine potions. Divine potions provide the same level of stat boosts as the base potion they are made from, but renew their boost every 15 seconds for 5 minutes instead of the boost reducing by one level per minute as normal potions do.
Crystal shard dust can be made by using a pestle and mortar on crystal shards, to create 10 dust per shard. One dust is used per dose (similar to amylase crystals in stamina potions); therefore, a single shard provides enough dust to create two and a half full divine potions.
