Crystal Slayer Guide

What is Crystal Slayer?

Crystal Slayer is an entire category of slayer unique to Xeros. You can acquire Crystal tasks starting at Slayer level 70. It is very strong in early-mid game with many common drops of Rune and Dragon items and often more supplies than you could get by skilling. It also gives you access to the Crystalline boss, Hunllef, which can drop some of the best Ranged and hybrid gear in-game - along with the Blade of Saeldor.

Gearing Up

Crystal Slayer is relatively easy and does not require much to get started. Any combat style is viable, although I recommend using your best Range or Melee gear. It is also highly recommended that you have 43 prayer for protect melee, as this will allow your trips to be a lot longer.

Highly Recommended

Dwarf Multi Cannon

Elven Signet

The Elven Signet is a ring bought from the slayer shop which will increase your maximum melee damage against Crystalline Monsters, and the imbued version (Celestial Signet) also auto-loots Crystal Shards for you. It is recommended to wear either this or a Ring of Wealth (i) in the ring slot.

How To Get A Task

To start Crystal Slayer:

Starting Your Task

Once you have a crystal slayer task from the Elf Tracker, open the teleportation menu and go to:

After you teleport, clicking the cave entrance will give you the option to pick Regular, No-Cannon, or Premium.

There are a total of 9 different Crystalline monsters inside the Cavern: Bats, Spiders, Rats, Bears, Unicorns, Scorpions, Wolves, Dragons, and Dark Beasts.

Crystal Shards

Each Crystalline monster you kill will drop a few Crystal Shards. It is possible to pick these up automatically, by wearing a Celestial Signet (obtained by using Imbue Dust on the Elven Signet, from the slayer shop).

Crystal Shards can be used to enter the premium cave, at 1,000 shards per entry. But they can also be used to make Divine potions. By using a Mortar and Pestle bought at the General store or Ironman shop, you can crush the Crystal Shards into Crystal Dust.

Once you have the Crystal Dust, you can use it on potions to convert them into Divine Potions. Divine versions of a potion give you its maximum stat boost for 5 minutes without the stats automatically decreasing. It is recommended to use the Dust on Super Combat potions or Range potions.

Crystalline Keys

Crystalline Keys are a rare drop from any Crystalline monster. These keys can be used to fight Hunllef, the Crystalline boss.

Having a Crystalline Key in your inventory will unlock the "Hunllef" teleport, in the Boss Teleports section of the interface. That teleport will take you just outside Hunllef's lair, deep in Crystal Cavern. Entering his lair will consume your Crystalline Key, so you will not get it back if you die.

Hunllef Mechanics

Loot

Once you have killed Hunllef, you will be given one Hunllef's Key (MUST have an open inventory slot for this, or the key will be lost) and automatically teleported outside Crystal Caverns, where you can click on Hunllef's chest to acquire your loot.

Rare items from Hunllef's Chest are full Crystal equipment, full Corrupted equipment, Blade of Saeldor, and Youngllef (the pet). Although, even the common loot can be quite valuable. You can check that loot table and all the others by doing ::mbox in-game.

Good luck!
