Crystal Key & Chest Guide

Introduction

Crystal Keys are made from combining a Tooth half of key and a Loop half of key which are obtained through killing monsters that drop each piece. You can also buy the half pieces and the complete Crystal key on the Grand Exchange or from other players.

Some monsters may drop a completed Crystal Key. Most players will ignore/high alch the pieces but saving them and combining them can be very useful, especially for an ironman.

Chest location

When you have assembled your Crystal Key you can take your key to the closed chest here in Taverly. You can easily get there by clicking teleport on your Crystal key or by going to your spellbook → Towns → #B Taverley

After teleporting, go to the chest and use the key on the chest.

How to obtain a Crystal Key

There are a wide range of monsters that drop pieces of a Crystal Key and a select few that will drop a complete Crystal Key.

Drop Tables

There's only one monster that has a triple drop chance for the Loop and Key half pieces, which is the Cyclops with the chances being Rare, Very Rare, and Ultra Rare.

The full drop table can be found on the official Wiki Drops Page. This page will automatically update if any changes are made.
