Dragonstone dragon

Dragonstone dragons are high-level Slayer monsters released on 3 April 2017. They are part of the gemstone dragon group, and are the weakest dragon of this type. 95 Slayer is required to kill them.

A total of six dragonstone dragons are located under the Shilo Village mining site. They require the completion of the Hard Karamja Tasks in order to access them in the gem rock cavern underneath. In order to pass the barrier to confront them, players are also required to sacrifice a number of uncut dragonstone, uncut onyx, or uncut hydrix gems - with each gem type allowing the player to kill a certain (2, 400, 4000 kills per gem) number of dragons within their respective chamber; up to a limit of storing 60,000 kills at a time. If the player is on a Slayer task for dragonstone dragons, however, they may enter the dragonstone dragon area without the need for charges, and, if the player has already donated gems for charges, the charges will not be consumed while on-task.

Dragonstone dragons, as with all Gemstone dragons are not affected by Dragon slayer gloves.

Strategies
Dragonstone dragons attack primarily with magic, although they will use both magic and melee if within melee range. In addition to the typical dragonfire attack.

Dragonstone dragons will periodically use their special attack, which sends a purple trail to the players initial spot (similar to glacors) which erupts into a 4x4 square, dealing up to 4500 magic damage and draining the timer on any antifire potions currently in use. Protect/deflect from magic will decrease the damage, but will not negate the secondary effect.
