Idle Slayer - Steam Achievements Guide

At the moment of writing this the game "Idle Slayer" has 641 achievements on Steam. Here is a guide to help you navigate through them.

Introduction

This is more of a list, rather than a guide. Since there are a lot of achievements in the game, dividing them into groups makes the navigation way easier, and that was exactly what I wanted to achieve by creating this guide.
If you need more information about any game mechanics/currensies/quests etc., I recommend visiting the game's wiki.
The game still receives updates, I do keep track on them and will be updating the guide when I have time to do so.

Final Words

Thank you for reading my guide. I hope it was helpful!

[SiegeFalconIX]

Thanks for the run through

[ACID JUNKIE]

Thx

[juanjbaena]

thks

[Magister Septimus]

Maybe. It changed place after i had found it though. So to find it, it may well be at the first place i looked into.
Well day three and i'm still stuck with first day played.... I guess i'll try to erase my progress :/
I'll check with the discussion tab if it's not a bug first though.

[SadSensei]

@Magister Septimus, changing time on your device doesn't help with the "days played" achievements (nor with getting offline resources faster). This number is tracked inside the game, not via the device settings.

About the secret achievement - for me it is first in the fifth line from the bottom, like your previous comment. Maybe it changes positions with the game's window size.

[Magister Septimus]

Btw now the special achievement is in the 6 ligne, 4 row in the left. Maybe because i found him?

[Magister Septimus]

It said one but i started playing yesterday at 10 am.
I tried to do like cookie clicker and move the clock manually to get the one year achievement, maybe that has broken a bit things? I'll update it if it doesn't change.
No worries. You guide is of great help^^ TY for that!

[SadSensei]

@Magister Septimus, maybe it is. There should be a "days played" counter or something like that somewhere in the menu, check what it says.
Also, thank you for notifying about the secret achievement! I guess it moved positions after more achievements were added.

[Magister Septimus]

I'm at my second day playing but nothing happened. Is it a bug?
For the secret achievement to find, it was first left, on the fifth lane from the bottom for me.

[SadSensei]

@Lubibinho, seems like it isn't. One achievement (in steam, at least) was definitely removed with the latest big update and some more were added. I still haven't checked which one was removed, so thank you for the notification!
I will update the guide at some point.
