Coupel of tips/secrets from the russian forum (not tested)

[Handel]

This is a rough translation of couple secrets @ tips found on the russian forum (I did not test them)
1. If you equip the "clay bowl" and go to the dragon nest in Vernon Wasteland there will be no battle but instead you will get a free black dragon egg.
2. If you equip the "torn boots" (forgot the exact name of the artifact - torn, destroyed, shredded or something like this) and go to the tavern keeper in Arlania, he will give you a package (don't know what is in it).
3. There is at least 1 secret room in the dungeon of the destroyed castle (where the ghost sits and tells how to get out). You have to click on a torch roughly opposite of the king's bedroom.
4. For those like me which don't know how exactly the raven works:
- he (it?) can write one wanderer scroll every 10 fights. If the raven agrees to eat a thorn seed, the number of fights is reduced considerably.
- if you click on the 3rd line (about the saga) he will replenish a random amount of rage, mana or both. This ability is recharged through battles and you can stack up to 3 charges.
Hope this helps

Edit: Just checked the secret room. The torch is near the entrance of the king's bedroom. There were 2 chests with items and a leadership banner inside.
Edit: Now I tested how exactly the raven writes scrolls. If left w/o food he writes 1 scroll per 10 battles. BUT after 5 battles he can eat a thorn sprout and after the next battle the scroll is ready. Providing the Ancient Knowledge scroll lasts 5 battles this means you can spam it (after you find at least one AND you need a source of thorn sprouts) and fight only one battle from every 6 without bonus XP.

I can confirm the part about the raven telling a saga.

think someone has mentioned the clay bowl trick aswell.

Didn't know about feeding thorn sprouts to speed up wanderer scrolls.

However, each wanderer scroll he make costs you about 5 crystals. I'm so crystal poor because of this, but the price to pay to get early Archdemons/Ice Dragons!

By the way guys, you do NOT need the raven equipped to write scrolls anymore. Also, he won't notify you when he finished. Just check your wanderer inventory.

Pretty odd that this run through I've gotten nearly every wanderer scroll whereas last one I did not get much. It is due to my archdemon. Love those guys.

Very good information, thanks Handel!
