Published 29 Aug 2026, 4:01 pm · 8 min read
Anime Squadron Update 3.75 is a smaller update, but it adds a pretty important new Divine unit, Sid, also known as Shadow Atomic. Alongside Sid, we also get a new corrupted stage, new rewards, codes, gear changes, and some useful improvements for newer players.
In this guide, I’ll show you how to get Sid, what you need to do to unlock his Divine form, and how to complete the new Underground Ruins Corrupted Stage. I’ll also cover the new codes, drop rates, quest requirements, and the other changes that came with Update 3.75.
The good news is that this update is quite friendly to free-to-play players. You can even use the team provided by the game to clear the new stage, so you don’t necessarily need an extremely powerful setup to get started.

Anime Squadron Update 3.75 Guide – Divine Cid, Codes
There are two new codes to redeem in Update 3.75:
Update3.75! Reward: 100 Rolls + 1,500 Gems
ShadowGuardian! Reward: 50 Trait Rolls + 1,500 Gems
I recommend redeeming both codes as soon as possible. The extra rolls, trait rolls, and Gems are especially useful if you’re trying to build Sid and work toward his Divine version.

The free Game Pass Voucher at Level 75 is particularly useful for free-to-play players, as it gives you another valuable reward simply for progressing through the game.
How to Get Sid
The new Corrupted Stage is where you’ll want to go if you’re trying to obtain Sid.
From the lobby, head into the play area and select the option for Corrupted Stages. You’ll see different stages available, including the one connected to Sid.
The Sid stage gives you a 0.25% chance of obtaining the unit directly.
There are also other rewards available from the stage, including:

• Shadow Sword
• Prisms
• Gems
• XP
• Sid
The Shadow Sword has a listed 0.5% chance, while Sid himself has a 0.25% chance.

There is also a pity system, which makes the grind much more manageable if you don’t get Sid from the normal drops.
Underground Ruins Corrupted Stage
The new game mode is called the Corrupted Stage, with Underground Ruins being one of the main stages connected to Sid.
To access it, go into the play menu and look for Corrupted Stages. You can build your own difficulty using the available modifiers.
There are different options available, including stages connected to other units such as Gojo, while the Sid stage is the one you’ll want for his rewards.
How to Beat Underground Ruins
One of the best things about this update is that you don’t necessarily need an endgame team to clear Underground Ruins.
The game actually provides a recommended team that you can use.
When I tested the stage, I decided to use the present team supplied by the game rather than relying entirely on my own units. This makes the guide more useful for newer players because you can see what the game itself recommends.
The provided team included units such as:
• Uta
• Sukuna
• Gojo
• Nezuko
• Fast Wagon
The team also comes with useful traits, including Cloner on some units.
Use the Provided Team
If your own team isn’t particularly strong, don’t worry.
The game gives you a preset team specifically designed to help you get through the stage. This means you can potentially start farming Underground Ruins without having a completely optimized account.
The game shows an average clear time of around 4:30, although the actual time can vary depending on your setup and how efficiently the units clear the stage.
AFK the Stage
Once you’ve selected your team and placed the units correctly, you can essentially let the stage run.
This is especially useful because Sid’s Divine quest requires you to complete Underground Ruins 50 times.
Rather than manually playing every single run, you can set up your team and allow the stage to clear repeatedly.
If your own team is strong enough, you can use it to improve your clear times. However, the provided team is a great starting point if you’re still building your account.
Sid’s Secret Passive
Once you obtain Sid, you can check out his Secret passive.
Every 15 seconds, Shadow summons another shadow that fights independently.
Each shadow copies:
• 10% of damage
• 10% of HP
Sid can have up to 5 active shadows.
This gives Sid a unique playstyle where his power gradually increases as he builds up his shadow army.
How to Get Divine Sid
Getting the basic Sid is only the first step if you want his Divine version.
You’ll need to complete his Divine Quest Line.
The requirements include:
• Complete Underground Ruins 50 times.
• Summon 1,000 shadows using Shadow.
• Reach Level 50 on Shadow.
• Roll a Mythic trait on Shadow.
• Roll Triple S stats on Shadow.
These requirements might look intimidating at first, but they’re fairly manageable if you’re actively playing the game.
The 50 Underground Ruins clears will probably be the biggest grind, while the trait and stat requirements will depend on your available resources and luck.
How to Complete the 1,000 Shadow Requirement
Sid’s kit naturally helps with this requirement because his passive allows him to summon shadows during gameplay.
Every 15 seconds, he summons another shadow, with a maximum of five active at a time.
So, the easiest approach is simply to keep using Shadow while farming stages. Over time, you’ll gradually build toward the 1,000 shadow summons requirement.
Reach Level 50 With Shadow
You’ll also need to level Shadow up to Level 50.
Feed XP to the unit and continue using it until you reach the required level.
This is one of the more straightforward Divine quest requirements, so you shouldn’t have too much trouble completing it if you have enough XP resources.
Roll a Mythic Trait
Another requirement is to obtain a Mythic trait on Shadow.
Head to the trait reroll system and use your Trait Rolls to try for the required rarity.
This is where the new ShadowGuardian! code can come in handy because it provides 50 Trait Rolls.
If you don’t get the Mythic trait immediately, you’ll need to continue rolling until you meet the requirement.
Roll Triple S Stats
The final major requirement is getting Triple S stats on Shadow.
You’ll need to use the stat reroll system to improve Shadow until you reach the required Triple S result.
This can take some resources, so I recommend saving your stat-related items rather than wasting them before you’re ready to build Shadow seriously.
Shadow’s Divine Form
Once you’ve completed all the Divine quest requirements, you’ll be able to unlock Shadow’s Divine form.
The update essentially gives you a progression path from obtaining the unit to leveling it, improving its stats and traits, farming Underground Ruins, and eventually unlocking the Divine version.
Free Game Pass Voucher
Another nice addition in Update 3.75 is the Free Game Pass Voucher at Level Milestone 75.
This is particularly good for free-to-play players because it provides a valuable reward without requiring you to spend Robux.
If you’re already close to Level 75, make sure you keep progressing so you can claim it.
Gear Changes
Gear has also received several improvements.
A search feature has been added to Gear, making it much easier to find specific equipment when your inventory starts getting crowded.
The Gear equipment system has also been reworked, and the update fixes issues where incorrect stats could be assigned to Gear.
These changes should make Gear management much less frustrating.
Awakening Search
Search has also been added to the Awakening menu.
This is another small quality-of-life change, but it’s very useful once you have lots of units.
Instead of manually searching through your entire collection, you can quickly find the unit you’re looking for.
New Shops and Items
Update 3.75 also adds new shop bundles, including an Update 3.75 bundle.
There are also new Shadow-themed items connected to Sid, including the Shadow Guardian and Estimation Mark mentioned in the update.
These additions fit the theme of the new unit and give players more things to collect while working through the update.
Best Strategy for New Players
If you’re a newer player and want to work toward Divine Sid, I’d recommend following this order:
• Redeem Update3.75! for 100 Rolls and 1,500 Gems.
• Redeem ShadowGuardian! for 50 Trait Rolls and 1,500 Gems.
• Enter the Corrupted Stage.
• Farm the Underground Ruins stage.
• Use the provided team if your own team isn’t strong enough.
• Obtain Sid from the 0.25% drop or work toward pity.
• Level Shadow to 50.
• Summon 1,000 shadows.
• Roll a Mythic trait.
• Roll Triple S stats.
• Complete Underground Ruins 50 times.
• Finish the Divine quest and unlock Divine Sid.
Anime Squadron Update 3.75 may not be the biggest update we’ve seen, but it adds a lot of useful content around Sid and makes the game more accessible for free-to-play players.
The 0.25% Sid drop means you’ll need some luck or patience with the pity system, but once you get him, his Divine quest is fairly straightforward. The provided team also makes Underground Ruins much easier for newer players because you don’t necessarily need an incredibly strong account to start farming the stage.
Don’t forget to redeem both new codes, especially the Trait Rolls from ShadowGuardian!, and start working toward the 50 Underground Ruins clears, Level 50 Shadow, Mythic trait, Triple S stats, and 1,000 shadow summons.
Once you’ve completed everything, you’ll be well on your way to getting Divine Sid / Shadow Atomic and preparing your account for the next major update.
