First of all, this is my first guide, so if you have any recommendations or tips to improve it, don’t hesitate to let me know.

I created this guide to help people unlock all achievements in Reignbreaker. If anything is unclear or you have questions, feel free to ask in the comments section.

100% Difficulty: 2/5

Average Time to 100%: 20–30 hours

Missable Achievements: None are truly missable. You can do everything in a single save, but you’ll need to complete at least 83 runs (you must reach the end of the Bastion 6 times and die 77 times).

Good luck to everyone hunting these achievements!

Rebel Girl
Break the Overseer and show what you can do.
Defeat the Overseer, the first boss you encounter after two areas.

A New Morning, Changing Weather
Break the Spitface and show the world who you are.
Defeat the Spitface, an alternate boss that appears after killing the Overseer. After that, you will have to fight them together.

Guerilla Radio
Encounter the Chimera and show the world how it should be.
After defeating both the Overseer and Spitface, you’ll face the Chimera after two more areas and a boss room. Defeat her.

U Should Not Be Doing That
Break the Corrupted Knight and let the queen know what comes for her.
In your next run after defeating the Chimera, face and defeat the powered-up Chimera.Be careful, it has now two health bars.

You
Encounter the Queen and witness what she can do.
Defeat the Queen after progressing through two areas post-Chimera.

I Am A Reignbreaker
Break the Queen and change the future.
Defeat the Queen a second time after six areas and two boss rooms) to complete the story and unlock the credits.

Cog In The Machine
Use their traps against them. Destroy 13 enemies using traps in a single fight.
Push enemies into traps. Avoid rooting them, as it prevents movement. Use the javelin with the tornado bayonet, Gear Glue mod, and Javelin Strike upgrade for easier control

Lockcrack Bop
Power up to deal 1000 damage with a single hit.
Use buffs and gear that increase impact damage. The explosion bayonet with critical-hit scaling works well. Build up a combo and unleash an explosive strike.

Rat Race
Reach the end of an area in under 1 minute.
Boss rooms count! Use speed boosts and the explosion bayonet. It's easiest against the Overseer, who only has one health bar.

Sabotage
Lockburst 666 enemies.
Kill enemies and use the lockburst mechanic. You’ll get this naturally over time.

Suck it Up
Improvement requires effort. Deal 25343 damage to Training Dummies.
Only works in the Training Grounds. Use the explosion bayonet -again-, group up dummies, and blast them repeatedly.

Soft As Molten Steel
Never wanted to travel far from home.
This one should go among the secret trophy but since it is related to combat prowess -or skill issue here- i decided to put it here. To obtain it you just need to die in the first area after you leave the camp - where you get your first item- and that's it.

I Can't Do Anything
Master the art of never staying down, die 77 times.
Just die, not really hard, but in case you finish the game before you obtain it, just go into the bastion, and blow yourself up with the explosion bayonet.

Baby, I'm An Anarchist!
Enter and leave the bastion without taking a hit.
Easier to do on the first run since you only have to kill one Boss, The Overseer, but can be done at the same time you do F**k Authority. You just need to avoid taking damage i think the best way is to play explosion bayonet - The GOAT- and use some launch buff from the sister -purple buff- but if you have skill you can do it with everything.

F**k Authority
Humiliate the Queen with a perfect victory.
You need to kill the Queen without taking a single damage it is a little bit hard but there is a trick to do this success and I'm An Anarchist easily -if you can accept being a fraud- just go into the options and activate the invulnerability in the accessibility section to get it easily.

Eat The Rich
Give yourself an upgrade.
Just buy anything in the resolve upgrades.

When The Wall Falls
Unlock all Utility character upgrades.
Prioritize this tree for increased Resolve gain, which helps unlock other upgrades more quickly.

To Them Streets Belong
Unlock all Survival character upgrades
Goes with "When The Wall Falls", " " Wake up" and " Up for Sale". Not really missable just don't forget to spend your resolve once you go back to camp.


Wake Up
Unlock all Combat character upgrades
Same as the others not missable and pretty easy you should all get it quicly if you use the upgrade which give more resolve.


Up For Sale
Unlock all character upgrades
Simple and self-explanitory as long as you spend your resolve everytime you go back to camp you should get it before you finish the game.

Not Yours
Find a shiny new toy and use it.
You get it after you pick up the first javelin, there is two way to obtain javelins, breaking the statue with purple shield you can find them in the room with no items at the end of every area or if when you start an area you see a chronometer in the upper right it means a javelin will be available once you reach the end quick enough usually you need to reach it under 3.00 or 4.00 minutes but if you missed it you can try again later don't worry.

Replace
Collect 10 javelins.
All javelins are obtainable with the two methods descripted under the previous success if you dont have them all just start a new run.

Rich Man War
Collect 25 javelins.
Same as the others break the statue with purple shield and try to beat all the chronometers.

Let Them Eat War
Collect all javelins.
In the options, you can activate Unlimited Dash in the Accessibility section. This makes it even easier to go through the map and find these javelins.
Be careful when you defeat the Queen for the first time — she drops a javelin named "Dancing Flames", which can be missed and won't be obtainable again later.
Thanks to Fenrir for the info.

Night Nurse
Patched up and ready to chat
Talk to Evangelyne after defeating the Queen twice.You must speak to her after each run when there’s an exclamation mark above her. Complete her dialogue to unlock this.

Soldier Girl
Make a friend
Talk to the Spear Sister after picking up her items and defeating the Queen twice.Speak to her at least three times (once per run). Use upgrades to increase her item spawn rate.

The Huntmaster
Hunters will be hunted
Same as Soldier Girl trophy you need to talk to him by picking up his items after defeating the queen until you get the success. If you have difficulty meeting him just use the upgrade who improve the appear rates of his items.

Broken Bones
Gonna patch you up, if you have the keys
Same as above: collect items, use spawn rate boosts, and talk to him while you are doing a run.

Oi To The World
