This quest can be started by saying "quest" to the ancient smith located in the North Britain Blacksmiths shop (near the graveyard).

Once you start this quest, you CAN NOT restart it, so choose wisely, and DO NOT lose your crystal ball. The quest itself is divided into several parts.

By completing the first step, you must kill 10 points worth of monsters (table below) and when you turn in the crystal ball, you will be rewarded with a slayer weapon.

In the next steps, you must kill various points worth of monsters and when you turn in the crystal ball, you will be rewarded with slayer upgrade deeds. These deeds can be used on the slayer weapon you initially received to improve its damage and attributes.

When you have completed the last level of the quest, the ancient smith will ignore your character, stating "I don't need any souls from you anymore. Thanks for your help".

Here is a list of the monster types, and how many points each is worth. Please note that YOU must kill the monster. If you let summons do all the killing, or try to take a soul from someone elses kill, it will NOT work.
