Trial of the Scholar
1) This quest starts in the Einhasad Temple in the Town of Dion, with Magister Mirien. She gives you 168 dimensional Diamonds and sends you to High Priest Sylvain.
Trust me, you'll want to use as many as those diamonds as possible with this quest.
11) Maria asks you to track down some scrolls from the Leto Lizardman Warrior. At least you get out of town right?
13) If you go to Oren you can port to Plains of the Lizardmen to find the Leto Lizardman Warriors. They are not aggro, but the Overlords and Lord of Plain groups are.
You need 5 brown scroll scraps. Then go back to Dion, and Maria.
17) Jurek is in the Magic Guild, which is to the right of the temple across the water. He gives you a list of mobs to collect things from to bring back to him.
18) You'll need 5 Monster Eye Destroyer Skins, 5 Breka Orc Shaman Necklaces, and 2 Shackle Scalps. Once you have all this go back to Jurek in Giran. Monster Eyes and Shackles can
be found around the Plains of Dion, and the entrance to Dragon Valley off Death pass, respectively.
21) Cronos is to the left of the Gatekeeper, and you are forced to be rude to him but he calls you cheeky twice so fair's fair. Then it's back to the Magic Guild in
Giran, this time to Magister Dieter.
27) Walk over to the Harbor and Drunkard Triff (/target Triff) is along the left side of the Harbor across all the walkways, all the way to the back. He sends
you off to find two people, Blacksmith Poitan in Dion and Warehouse Keeper Valkon in Giran.
29) This step is optional, you can go right to Valkon in Giran. If you choose to visit Casian anyway, you can either port from Gludio to the Ants Nest and run South, or go to Gludin and ports to the Wastelands and run North to find him. He's behind the big spire rocks so a /target Casian will be useful. He says nothing at all useful.
Go to Giran to the Warehouse to see Valkon.
33) Casian gives you a list of things to collect to bring back to him. You're almost done with the quest!!
34) You need 10 Ghoul Skins, 12 Medusa's Blood, 5 Fettered Soul Ichor, and 5 Enchanted Gargoyle Nails. Only Medusas are aggro, you can find the mobs in the following locations.
When you have all the parts return to Casian.
37) In Dion talk to Mirien and you're DONE! The reward used to be Mark of Scholar, 80,2665 exp and 30,000 SP, nowadays it's Mark of Scholar, 159,814 adena, 876,963 exp and 56,877 SP.
