Eager for Battle

5) Boxcars

In the battle against Ten Stonehearts: Aventurine of Stratagems, cause at least 2 "All or Nothings" to simultaneously roll a 6 with a single attack. Before starting, I would like to remind you to bring characters that can deal AoE or Blast attacks (whether on their Basic/Skill/Ultimate) to increase your chance to win. Then, attack Aventurine until he enters his second phase so he can summon 4 dices instead of 2. Use all your Blast/AoE attacks on the dices and pray you got 2 of them to roll a 6 (It's not as hard as I expected as I got it accidentally).

6) All My People, All My People…

In the battle against Ten Stonehearts: Aventurine of Stratagems, have 4 characters in the team win in the same round of Gamble. What you need to take advantage here is ability to hit the dices multiple time by using the Ultimate loophole. In other words, make sure all your teammates have near full Ultimate > use their attacks to gain the remaining Energy > use their Blast/AoE Ultimate to deal damage to all Dices and get points higher than Aventurine.

7) Lady Snowblood

In a single battle, using Acheron's Ultimate "Slashed Dream Cries in Red" to defeat all enemies and achieve victory in the battle. While the description mentions using Ultimate to defeat all enemies, I still get the achievement after Acheron uses her Ultimate (but the enemies didn't die yet) and then uses her Skill twice to defeat the enemy.

8) Blind Stealing

In a single battle, when Blind Bet is at 0 point(s), use Aventurine's Ultimate "Roulette Shark" to obtain 7 Blind Bet point(s). You can play Trial Aventurine during the Trailblaze Mission (or just wait until phase 2). His Ultimate will give a random amount of Blind Bet points (minimum is 1 and maximum is 7) so you may need to try this multiple times.

First of all, you need to make sure his current Blind Bet is 0 (can be seen from his icon. When he has 7 Blind Bet, Aventurine will use his talent 'Shot Loaded Right' to deal damage to enemies and renew your team's shield, while also resetting the Blind Bet to 0 (+ more if he got more than 7 Blind Bet).

When he only has 0 Blind Bet, use his Ultimate and pray you will get another 7 Blind Bet. Remember that it's random so you may going to repeat this process multiple times.

9) Purging Heatiness

Clear the full stacks of Obscure Blaze on the Memory Zone Meme "Shell of Faded Rage" during a Weakness Break. There are multiple ways for this boss to earn Obscure Blaze stacks: deal Quantum damage or use certain skills to gain stacks. The maximum number of Obscure Blaze stacks it can get is 5 times.

Since the description mentions clearing the full stacks, I'd recommend you to wait until it has 5 stacks of Obscure Blaze (open the Enemy Details to view how many stacks it has) before Weakness Breaking it. Once you Weakness Break it, all the stacks will disappear and you will get the achievement.

10) Fight Fire With Fire

In a single battle, defeat Memory Zone Meme "Shell of Faded Rage" without causing Weakness Break. This one is pretty easy, just bring characters that do not match with the boss' weakness and go to the lowest level to complete the challenge. Honestly, you can still bring characters with the same elemental weakness at the lowest level. If your DPS is too strong, they will defeat the boss with a few hits without Weakness Breaking.

11) Performance Evaluation

Use ally Aventurine to fight Senior Staff: Team Leader and deal the finishing blow. Go to Forgotten Hall and check the lower floors for the Senior Staff: Team Leader. When I'm writing this, there's one of them in Stage 2 (Forgotten Hall: Chronicle of the White Nights Dream), so you can bring your Aventurine and make sure he deals the finishing blow.

12) Divine Judgment Does Not Discriminate

During exploration, use Acheron's Technique "Quadrivalent Ascendance" to defeat 5 enemies consecutively. You can easily complete this achievement inside her Character Trial because they have prepare 5 mobs for us to take care of. But remember to keep using her Talent and make her stay inside the black-white world while defeating 5 enemies consecutively or it won't count. Well, you can just re-enter this stage if you failed.

Moment of Joy

13) Why Is the Origami Bird So Huge?

Yank out the Origami Big Bird at Dewlight Pavilion. First of all, go to the City Sandpit from the Dewlight Pavilion. Use the Bubble Pinball Machine to get to the upper level of the City Sandpit. There, you will find a huge Origami Bird stuck on the huge billboard. Talk to it and it will ask you to find the finest wine.

Next, teleport to the Reception Counter in Dewlight Pavilion and head to the spot above to see 3 wine bottles floating. Talk to them until the end and you can choose one of the three bottles. I don't know if it will affect anything, but I chose the Yellow bottle. Bring back the bottle to the Origami Bird and you can yank it out to get this achievement + a sticker for your Dreamscape Pass

The Memories We Share

14) Attendance Rate, Zero

Make Radiant Speedster lose its fans. Defeat the enemies surrounding a sports car in Clock Studios Theme Park and you will get this achievement.

15) Birds Art Life: A Year of Observation

Become a master bird observer at Dewlight Pavilion. Go to the room above the Reception Counter in Dewlight Pavilion and interact with all 6 statues. After that, interact with any one of the statues one last time to get this achievement.

16) For Great Goods

Obtain all 4 Clockie merchandise. Go to Themed Restaurant Server in Clock Studios Theme Park, and but everything from the menu to get the achievement.

17) The Cabin in the Woods

Witness the bizarre experience of the five at a certain place in Clock Studios Theme Park. There are 3 spots in the Clock Studios Theme Park you need to go in order to complete this achievement. Keep in mind that I find them in this order:
1. Listen to the group of NPCs in a secluded area, you can reach them here using the Bubble Pinball Machine.

2. The second spot is inside a closed space. You can only reach this place after turning into Hanu and entering a vent near that location (you won't miss it). But once you enter the room, change back to human form or you can't interact with them.

3. The last spot is at the Screening Area Entrance (west side of the Clock Studios Theme Park). This time, all of them are in human form so just approach them one last time and you will get this achievement.

18) Proofs And Refutations

Purchase a certain good from a food truck owner at a high price during a conversation. Talk to Warner in Clock Studios Theme Park and buy the Soulglad from him for 2000 Credits.

19) A Variation Named "I"

Meet a "detective" with peculiar physical attributes in Clock Studios Theme Park. Go to the spot above and you will see a Billboard Investigator surrounded by a bunch of popcorn. Talk to it until the end and whenever you have to choose an option, I choose all the top answers.

After a daily reset, you will get a message from the Billboard Investigator regarding the case. Close the message and you will get this achievement alongside a sticker.

20) The Lady in Gold

Investigate the portrait of a certain famous performer at Dewlight Pavilion. Currently, there is NO method to obtain this achievement and we can only wait until the next update. I will include this achievement in the next version's achievement post if we can get it later.

21) Lord of War

Bring Oksana to justice. Talk to Oksana near the Dreamville-Themed Restaurant in Clock Studios Theme Park and use Happy Gear on her to start the Adventure Mission 'Clockwork: Oksana.' Based on your choices, you will either get Lord of War achievement, Better Late Than Never, or Dishonored Legacy achievement (only one of them).

22) Better Late Than Never

Expose Oksana to the Bloodhounds. Talk to Oksana near the Dreamville-Themed Restaurant in Clock Studios Theme Park and use Happy Gear on her to start the Adventure Mission 'Clockwork: Oksana.' Based on your choices, you will either get Lord of War achievement, Better Late Than Never, or Dishonored Legacy achievement (only one of them). Unfortunately, I already got the first one, so I don't know how to get this achievement. If you do, feel free to share in the comment~

23) Dishonored Legacy

Let Oksana go. Talk to Oksana near the Dreamville-Themed Restaurant in Clock Studios Theme Park and use Happy Gear on her to start the Adventure Mission 'Clockwork: Oksana.' Based on your choices, you will either get Lord of War achievement, Better Late Than Never, or Dishonored Legacy achievement (only one of them). Although I already got the first one, pretty sure the branch here is when you need to choose between 'You can keep your filthy blood money' that will lead to Lord of War achievement, while choosing 'That's what I meant' will lead to this achievement.

24) Big Shot!

Leave your special mix at the Dreamjolt Hostelry. After completing all the event missions in Vignette in a Cup, you'll have a chance to mix a drink with your name. Complete it and you will get this achievement.

25) Make Your Dream a Blast

Help all the monsters in the Dreamjolt Hostelry deal with their emotional troubles. You will automatically get this achievement after completing the Vignette in a Cup event. A more detailed guide about the event can be seen here: Vignette in a Cup Event Guide

26) To Each Their Own Drink

Serve the correct drinks to the customers 10 times. During Vignettes in a Cup, follow the instructions given by customers and get them the correct drinks. A more detailed guide about the event can be seen here: Vignette in a Cup Event Guide

27) Omakase

Serve the wrong drinks to the customers 5 times. After you complete the whole Vignette in a Cup event, you can still mix drinks for customers. There, just give random drinks to them and you will get this achievement.

28) Operation Dreampunk Drinksmith

Complete all Dreamjolt Hostelry recipe deductions. There are a total of 12 recipes you can create from the Vignettes in a Cup event. A more detailed guide about the event can be seen here: Vignette in a Cup Event Guide

29) Family Portrait

Take a family photo of the Express Crew at the photo board in Clock Studios Theme Park. Go to the photo board of 4 people like in the image above (south of Clock Studios Theme Park), and when the options time come, make sure to choose all the Express Crew: Welt > Himeko > Dan Heng > March 7th. You can either get Family Portrait or "Clock" In achievement.

30) "Clock" In

Take a group photo at the photo board in Clock Studios Theme Park.

Fathom the Unfathomable

31) Home Alone

Defeat 3 of Boss Stone's minions at once in a Hanu's Adventure stage. To defeat enemies in Hanu's form, you need to use the Hanu Launcher and ignite a firework in the enemies' direction. You can find a Hanu Launcher in the 3D room west of the Dewlight Pavilion.

Conveniently, there are also 2 groups of enemies in this room. Wait until they group together before attacking them with the launcher to defeat them all simultaneously.

32) Anti-Balloon

Break the special Boss Stone balloon in Clock Studios Theme Park. It's easy to find, just go to the spot above and use any long-ranged character to hit the balloon on the platform hidden behind a building.

33) Saga of the Dreamhaven Tumult

Break the special Boss Stone Balloon in Dewlight Pavilion. Specifically, go into the City Sandpit and use the Bubble Pinball Machine to go to the third floor of a building. There, walk around the area to reach another Pinball Machine and you will see the special balloon floating between the building. Use any long-ranged character to hit the balloon.

34) Safety Car

Complete the shoot without any damage in any mode in Clockie's Extras. Look at the Number of Attempts on the top left. Make sure you have it full when completing the shoot, aka don't get hit by any enemies during the whole shooting.

35) Non-Racing Line

Stay in the middle lane continuously for 10 second(s) in any mode in Clockie's Extras. You will learn to stay in the middle lane in Way of the Wolf (Continued) Part 1. After you learn it, stay in the middle lane for 10 seconds. Then, end the shooting (you can either win or lose the shooting) to get the achievement. You will still get this achievement if the photoshoot fails.

36) Pole to Win

Re-accumulate maximum energy within the duration of Nutty Blitz or Hanu Time in any mode in Clockie's Extras. For this one, it's a bit complicated, but I recommend playing on Hamster Ball Knight: Fast & Furynuts instead of Brother Hanu: Way of the Wolf since the method to accumulate energy is easier and faster.

1. First, you need to enter the Nutty Blitz (where the background turn orange). You can do this by accumulating energy by triggering Turbo Dash and picking up supplies. Turbo Dash is when you dodge right before you're about to crash.
2. Once you're into Nutty Blitz, continue doing the same as what you're doing before which is collect energy by triggering Turbo Dash and picking up supplies.
Tips. When you're about to dodge an enemy to trigger Turbo Dash > Flip once again to kill the enemy that you just dodge. This way, you will gain double the energy since defeating the enemy during the Turbo Dash also gives energy. Please refer to the GIF above on how I do it.

37) Biggest DRS Beneficiary

Perform Turbo Dash 10 times in a row without mistakes or interruption in Clockie's Extras: Fast & Furynuts. Make sure you go to the Fast & Furynuts and not the Way of the Wolf. You can perform a Turbo Dash by dodging right before you're about to crash into a roadblock. In Fast & Furynuts (I) Part 2, there will be multiple enemies in a row and you can do the Turbo Dash 10 times in a row to get this achievement.

38) Slow Road to Hell

Defeat all enemies that appeared in Clockie's Extras: Way of the Wolf. Remember to go to the Way of the Wolf, and not the Fast & Furynuts. In the shooting, hit all enemies on both lanes before reaching the end to get this achievement.

39) A Dreamy Town, Oak Paradise!

Enter the miniature sandpit in Dewlight Pavilion for the first time. Complete the Trailblaze Mission [Cat Among Pigeons - Double Indemnity] and you will automatically get this achievement.

40) Dreamweaving Industrialization

Complete the Dreamwalker Challenge at the Dewlight Pavilion for some extra income. Complete the Adventure Mission Outsourcer to get this achievement. A more completed guide to get all the treasure chests and achievement was covered in another post: Outsourcer Adventure Mission | All 9 Treasure Chests and Route

41) To Get Blood Out of a Stone

Transform into Hanu and use Hanu Rocket to defeat Boss Stone's minions for the first time. You will automatically get this achievement if you've done the previous achievement, also at the same location.

42) Living With a Wolf

Collect the complete Hanu's Adventure (Part 2) collection. If you already collected all treasure chests, you should automatically get this achievement too cause all the Hanu's Adventure pages are hidden inside treasure chests that you can find when morphing into Hanu.
But if you haven't yet, look at the 4 spots in the image above and complete the Hanu-related puzzle to unlock the treasure chest, and you will get this achievement.

43) Maximum Firepower

Obtain the maximum ammo limit of Hanu Rocket in Hanu's Adventure. Enemies will drop ammo after being defeated. If one round of ammo hits multiple enemies, more ammo is dropped at once. In the same room as the Home Alone achievement, there will be 7 enemies, try to hit the 2 groups of enemies (3 enemies in each group) and you will get more than 5 ammo.

44) Secret Party

Discover Clock Studios Theme Park's hidden area via Bubble Pinball. Go to the location above in Clock Studios Theme Park and interact with the Bubble Pinball. Change the trajectory like in the image above to reach the hidden area.

45) Pac-Man

Smash all destructible objects in Clock Studios Theme Park's maze garden. First of all, go to this location to find a puzzle hat guy (I don't remember the exact name). Complete this puzzle to unlock the other half of the maze garden.

Then, go down to the maze garden and destroy every balloons you find until the end. It's in a long line so you shouldn't miss any of it.
