Hello, and welcome to what's left of the forum! I'm the one who's been trying to make a full walkthrough of the game, for quite a while now, lol. Life keeps getting in the way and making me put it on hiatus, but I'm determined to finish it one day or another! In the meantime I'm trying to at least answer any questions about the game anyone here may have, so here goes!
1. "Save Henrik" how can i get this quest, on what NPC?
Unlike most sidequests in this game, you don't actually get this quest from another NPC, you just have to simply find Henrik and talk to him to save him. This can first be done right after the 3Dazer on Day 13, when Luciana learns "Floyd's Beacon". First, set any teleport point, then enter the Slime's Nest, drop down to where you fought the Slime King, then jump down the right of the 3 pits to the south. You will come across an even deeper pit which you can't Egress out of if you jump down it, and down here is where Henrik is trapped. Talk to him to get him to join you as a comrade and get a quest completion. Then, simply Floyd's Beacon your way out, and go back to Metrolia's entrance gates to return him safely.
2. "Escort Mordock", why I don't get this quest from fighter guild? how can i get it
The only "Mordock" I remember is the one that "joins" you on that quest to get Duchess Melanice's jewels back to enter Bazizka Tower. This is part of the story.
3. "Bring package to Ubacca in Baluul", I dont get this quest too, On what day do i get this quest?
This one is gotten at the Fighter's Guild on Day 13. Simple enough, just get the quest and then talk to Ubacca, who resides in the inn of Baluul.
4. Where is the location of Xavier Dungeon when Baretta found secret recipe of Dan?
First, you have to get Baretta's Slayer Reward to Level 4. After that, it will appear just west of the Giants' Fortress.
5. How Can I finish translate the book quest on mage guild (I play non-import game)?
On non-imports, the Royal Encyclopedia is unobtainable, so you'll have to either get the Yuman's 5000 Laws book from the Guild of Fire after completing the quest for Baretta to get the Ox-Oramion back from the Ore Lab, or pay a ridiculous amount while at Gottwaldeyr (Island of the Giants) with Luciana in your party and at least 800,000 pp in your possession (though they actually only take 400,000) to get the Universalis Dogma.
6. Is there any hidden boss in mad world (laboratory institute when i touch red gem), how can i go into deeper?
There's no boss, and you can't go any deeper than that weird futuristic place with Dave.
7. How to catch Luba's Betrayal, I did not seem fiinding her betraying?
That was just a teaser, set up by DZK/Indinera (and I suppose the Cenodemons game-wise) to mess with you.
8. How to make black dragon appear after i open the quest or dream book? (I have met it but accidentally, I do not know how to get it out again)
That fight is a special, one-time-only event, that triggers on Day 13, after checking your Quest Book for the first time after checking the locked doors to Bazizka Tower.
9. Have you read "jack of all trades letter on mosquito swamp castle?" I have read it but i cannot find jack on coliseum
Yeah, I found this strange note, too, a while back. I found Jack at the Coliseum, too, but there are no additional events in the database associated with him. My best guess (though it certainly could be wrong) is that it was an unfinished event (probably a sidequest or special tournament or something) that DZK/Indinera planned but never got around to.
10. If someone can help, can someone make noticeable and prestigious victories on the list, so many monsters on my dream book have not yet been defeated
Yes, I have just composed a list, and will post it in a new thread shortly!
And there you have it! Sorry it took a while for a reply. Hope this helps! Just let me know if you need further clarifying or other questions!
