Research and Development Quest

Ask Spectulus for a task. This quest is part of the Tibia Tales.

First Mission is rather simple. Go to the Edron Graveyard hereand use the Magical Measurement Device Spectulus gave you on four graves (a Squidgy Slime will spawn each time the device is used). When you are done, return to Spectulus.

Talk to Sinclair and ask him for a mission. He will give you the Spirit Cage. Collect a sample of ghost in it. Return the filled cage to Sinclair. You will receive the achievement "Guinea Pig".

This is the point where the Spirithunters Quest starts. Speak to Sinclair. During this task you have to catch 5 Ghosts, 5 Nightstalkers and 5 Souleaters.
