Magister Iker:
All right, this is what I need.
First, the teeth of the Wyrm that lives in the Sea of Spores. 20 of them should be enough.
You must also bring me the Leto Lizardman's amulet. You can find the Leto Lizardmen in the southern parts of Oren. You must bring me 20 of these..
And last, I need the stoneheart of the enchanted stone golems that may be found near the Ivory Tower. I will need 20 of these...
These are quite a few items so I've written them down for you. Bring them to me and you shall have your jewel...
