An adrenaline crystal is a reward from Bounty Hunter. It costs 1,000 Bounty Hunter points to purchase ten adrenaline crystals from the Bounty Hunter & Deathmatch Reward Shop.

The crystal can be added to a 3-dose adrenaline potion or a 6-dose replenishment potion to upgrade them to a super adrenaline potion or enhanced replenishment potion, respectively. Upgrading an adrenaline potion requires level 87 Herblore and grants 200 experience, and upgrading a replenishment potion requires level 90 Herblore and grants 256.9 experience.

The upgraded potions grant 30% adrenaline instead of 25% when consumed (replenishment still provides the normal super restore effect).
