Crystal slayer

Where to start/ requirements In order to start crystal slayer you'll need 70 slayer, the Elf tracker (at the slayer masters in home or at the crystal cavern) can give you a task for 1m.

It can also be an asset to wear an Elven Signet, this causes you to automatically pick up the crystal shards.

How to get there These task takes place in the crystal cavern (the cave when you teleport to it) that can be found in the spell book under: Dungeons -> Crystal Cavern

Where you will have 3 options to enter the cave: Regular (you are able to place a cannon here) and you share this instance with others. No Cannon (self explanatory), but still shared with others. Premium, your own private instance.

Attached is also a complete map where you can see all the locations of the monsters.

Drops The biggest reason to do this slayer is because of the following drops: Crystal shards, these can be crushed with a pestal and mortar to create dust. Dust can be used to create divine potions. Crystalline key, a key that can be used to challenge Hunleff for a Hunleff key or alternatively be sold on the Grand Exchange. Crystal armor.

These keys can also be upgraded through ::upgrade or in home at the anvil, this will set you back 5m but you don't have to challenge Hunleff.

The Hunleff fight This fight is a bit tricky and you need to be prepared once you enter this instance there is no going back or you'll lose your key.

To fight Hunleff you need atleast 2 combat styles like melee and ranged. I'd advise at least barrows/ void before trying this fight, since there is no 100% surefire way to protect yourself from damage and of course attack Hunleff with the style he isn't praying against.

After a certain amount of damage Hunleff will change prayer and you'll have to switch your style (see attached GIF).

When starting this fight Hunleff will always start with protect from melee, so you should start with your ranged gear.

Inventory wise, I'd advise to make sure you are potted (with either an overload/ divine super combat and divine ranging / regular super combat and ranging potion), and that you are sure that you have enough prayer/ super restores and food.

Once you killed Hunleff you will get a Hunleff key, which opens the red chest at the Crystal Caverns. You can use a 15% chest rate here to increase your chances!
