How to unlock the Ultimate Stress Relief achievement in Tales of Berseria - Definitive Guide
The enemies range from Lvl 70 - 124 throughout the dungeon. It is recommended you attempt this in a New Game+ with 2x or 3x EXP but it can be done in your first play-through with some intense frustration and grinding. I had to be Lvl 98 to complete this. You will just need to progress as far as you can and grind where you are having issues.
The dungeon itself is a pain in the butt because of how it is designed. There is usually 3 rooms of puzzles and then a room with a big flame of malevolence. Enter it and defeat the waves of enemies. Upon defeating it, a timer will start and you will need to find tiny malevolence flames and defeat the wave of enemies with in them all before the timer ends. If the timer hits 0 it removes the small flames and the big flame reignites. If you complete the final flame after the timer hits 0, it still registers as a fail.
There is a Katz in the area that can make things easier for you but it will cost Katz souls. I recommend taking advantage of it to locate the small flames and extend the timer. These must be purchased before entering the giant flame, the purchase is also permanent per level. Once you complete that you can continue on to the Boss of the Floor. Defeat the Boss and the next room will contain another Katz. Speak with him and use 100 souls to create a warp point so that when you fail you can teleport there, rather than starting over from the start.
You will have to do this 6-7 times. This is also required to obtain the Dual Mystic Artes. 3 of the Bosses upon their defeat unlock a dual Mystic art. They are: Velvet\Laphicet, Eizen\Rokurou and Eleanor\Magilou
After beating the game, load the clear data. In Danann Highway nearby to the entrance to The Empyrean's Throne, there is a Katz. Talk to him for a scene. Go to Mount Killaraus to the second area inside the volcano, where a new fire portal appeared located nearby the Katz Chest. Do not forget to activate the new teleporter that also appeared nearby. Make sure you have at least 100 Katz Spirits before proceeding. Enter the portal. Follow the way until you are at the top of the volcano and enter the portal there.
You will now be in a small room with three Katz. Do not immediately touch the big dark aura. Instead, touch all the small thorny dark auras around the big dark aura, including the appearing auras when you get nearby. Once you have touched all of them and they disappeared, touch the big dark aura. When you have finished the battle, there will be a time limit. Within this time limit, you have to touch the three newly appeared small dark auras and fight their battles. The time limit will continue during the battle. If there were any thorny auras left, you would get a time penalty for touching them, which is why you removed them all beforehand. If the time limit reaches 0 before you could finish all battles from the small dark auras, you will have to try again.
Once you cleared this room, a new portal will appear. Enter this portal and talk to the Katz in the following room. Make sure you select the option to make a warp point here so that you can come back later. This will cost you 100 Katz Spirits, but the shortcut will come in handy later. Use the warp point to return to the first room of the dungeon and save. Warp back to the first floor and enter the portal. Now the actual Bonus Dungeon begins.
When you enter the portal, a random room from the following list appears:
- A room full of Katz Spirits, about 400. This is useful for the Katz Person trophy.
- A room with 9 treasure chests, with random content. This is useful for the Item Collector trophy.
- A room with enemies, in different variations of room layouts. Random treasure chests may also be in this room, but not as many as in the random room with the 9 treasure chests.
It is possible to warp out at any time. You can abuse it to get a result you want for this random room. Warp back out to the entrance of Mount Killaraus, go back inside the dungeon, use the warp point to warp back to the current floor you are in (or any previous floors), check what room you get after continuing. Then you can warp back out or proceed.
After clearing this random room on the first floor, a boss will appear in the next room. Defeat it and proceed to the next room. Here is a Katz where you can buy a warp point for 100 Katz Spirits.
The following five floors all work the same. After the room with the Katz where you can buy the warp point, a random room from the list above appears. After clearing the random room, a room with the layout from another part of the world appears where you have to activate a time limit by touching the big dark aura, and then clearing all small dark auras within the time limit. This is what you had to do at the beginning of this bonus dungeon, so you will know how it works. Clear the area of all thorny auras and possibly all enemies first before touching the big dark aura. After clearing the time limit, a boss room will appear. Defeat the boss and you will be on the next floor starting with a Katz where you can buy a warp point for 100 Katz Spirits, which you should definitely do. So in short:
Warp Point Room -> Random Room -> Aura Room -> Boss Room.
The Aura Rooms are fixed in the amount of treasure chests and the position of the auras and treasure chests, and you cannot avoid doing them. If you run out of items, there is one Katz which sells you items in exchange for Katz Spirits. Each Aura Room has one recipe you can collect, so make sure you get it since it is important for the Chef's Soul trophy. It is easier to collect them before touching the big dark aura and thus before the time limit starts.
- The Aura Room that looks like it is from Yvolg Ruins: The treasure chest with the recipe for Seashell Pasta Minestrone is located in the western room. 4 small auras can be found here.
- The Aura Room that looks like it is from Aldina Plains: The treasure chest with the recipe for Extra-Rich Soft Serve is located at the dead-end north-north-west. 6 small auras can be found here, one of them on the top platform.
- The Aura Room that looks like it is from Lothringen: The treasure chest with the recipe for Giant Squid Pizza is located in the central room. 6 small auras can be found here.
- The Aura Room that looks like it is from Hexen Isle: The treasure chest with the recipe for Special Miso Hodgepodge is located at the north-east from your starting point. 5 small auras can be found here.
- The Aura Room that looks like it is from The Empyrean's Throne: The treasure chest with the recipe for Pirate King Seafood Bowl is located at the central part behind the big dark aura. 7 small auras can be found here, 3 of them in the upper part.
Upon defeating the sixth boss, you will be at the end of the bonus dungeon. After watching the following scene, this trophy will unlock.
