The game itself is one of the best games on the Xbox 360, not just one of the best RPGs. However, like most RPGs the achievements take a long time to get and the "Treasure Trove" achievement will drive you insane if you don't follow the guide religiously.
Welcome to Lost Odyssey. This game has a total of 36 achievements and requires only one playthrough to get 1000. Of the achievements, four are unlocked simply by playing through the story. The rest will require you do collect items and perform certain tasks.
There are only two things that are missable in this game and if you do miss them you will not get the "Spell Collector " achievement. The following is verbatim from the spell location guide:
"Shieldus and Barricadus - Purchased from either Damiroh's Grab Bag (Experimental Staff) or Kessle's Tool Shop (Gohtza - Middle Town). ***Attention: These two spells must be purchased at one of these two points, when you arrive there, or they will be lost forever and you will NOT get the spells achievement.**"
Many people think "Treasure Trove" is a missable achievement, but it is not. If an area can no longer be accessed, its items will be in the auction house. Otherwise, you will need to return to an earlier location to find what you are missing. Follow the Treasure Trove guide linked below to save yourself about 30 hours of extra work, as that is what a "Treasure Trove" run will take.
Finally, there are many walkthroughs for this game. Two of the best are written by INVAL1D posted HERE, and a video guide by Split Infinity: Disc 1, Disc 2, Disc 3 and Disc 4.
Step #1: Prepare
One of the best and easiest ways to avoid frustration and rage at this game is to prepare. The following, in addition to the walkthroughs above, are important links that you will want to utilize at least one point during your playthrough:
- Locations of Everything!
- Treasure Trove Achievement Guide
- Character Leveling Guide
- List of Skills and Accessories
Step #2: Play the Game:
The easiest way to stay on track and still enjoy this game is to follow one of the two walkthroughs linked above. If you don't want to use a walkthrough at least use the Treasure Trove guide to keep track of what you have gotten and what still remains. If you don't keep track you may end up like the countless souls who have posted in this thread. Last, make sure you don't save after you beat the final boss in case you need to work on any other achievements.
Once you get to Disc 4, take the time to look at all the optional boss achievements. See the leveling guide to power up and then take down all the bosses. Remember to do the Backyard challenges just before the end of the game, spend time linking all your skills and equipping all accessories to get the "skill master" achievements. All you should have left to do is taking out the final boss and finish the game for good.
If you are missing achievements at this point you can load up an old save and go back and get them. That is unless you still ended up missing the two spells mentioned above. If you did miss those or can't find what you are missing for "Treasure Trove," you will need to start a new game, though you can use a New Game + to start all your immortals at level 50. No items, skills or spells will carry over though. Good luck!
Seeker of the Deep DLC:
Seeker of the Deep is a short; but challenging DLC addition for Lost Odyssey. It is available for download for $1.00 (originally it was $4.99). The DLC consists of 26 floors you must traverse to meet and beat one of the harder bosses in the game. The 25 previous floors are very straight forward and not at all difficult to navigate. There is random loot available on most levels as well as 'prizes' for completing every 5th level.
What makes the dungeon challenging is there are no save points. Should you return to the top from (as an example) Level 10, you can't return to that specific level; you'd have to start at level 1 all over again. And of course, should you die, you must start over from your last save outside the dungeon.
**Please note that none of the rings, accessories or chests have any bearing on the main campaign achievements.**
On the world map the Underground Research Division is located: HERE
The dungeon is available to access on Disc 4; once you have the 'White Boa' to explore the oceans. Upon arrival you will meet Cartographer Mardohl who will offer you treasure for every 5th level you reach (there are also no monsters on every 5th level). You can only return to the main level via the elevator that leaves from every fifth level as well. The treasures received are as follows:
- Level 5: 3x Ambrosia
- Level 10: 5 Godly Dragon Tears
- Level 15: 5 Slot Seeds
- Level 20: Mana Protector
- Level 25: 10 Slot Seeds
- Once you defeat the boss on Level 26: 5 Full Heals
It is recommended that you travel all the way down to level 25 and then return to the top, speak with Mardohl and receive your prizes, exit the dungeon and save (Remember there are no save points in this dungeon).
Here's a link to the wiki for additional drop and enemy info: Seeker of the Deep
Once you've collected all the goodies you want and have made your preparations to make a boss run; just do a speed run through the dungeon as best you can. Run from battles if necessary utilizing the 'Turn Tail' skill as you see fit; but the goal here is to make it down to the bottom floor to face Killalon. Upon reaching the boss, there are numerous strategies that can be applied, but they must be followed very closely. Mistakes are punished severely. Once Killalon is in a heap the final achievement will unlock and the DLC is complete!
Here is an excellent strategy if you are leveled and prepared: Professor K Boss Strategy
This is a very straight forward set of achievements and can be easily done if you are adequately prepared. With a few hours of time and a good strategy in hand you can finish this DLC and net your 100.
