Hi, I think this is a very good guide and wanted to say thanks for doing it because it is helping me to 100% this game that I love so much.

But I think that adding the amount of tinderboxes you need to collect throughout the game to get the achievement "Illuminatus" might be helpful for everyone, so I wrote it down, this helped me to keep track if I left any tinderboxes behind. This it's only for the main game because I think Justine doesn't count for the achievement.

The following list is cumulative, meaning the Tinderboxes you grab will be added up as you progress through the castle. So, rather than a list per location, it's a list of how many Tinderboxes you should have throughout the game if you don't use any for each map. If you think it's necessary to do it by individual location, you're welcome to do so, but I found it easier to keep track as follows:

Part 1: Entrance Hall (TOTAL 36)

Rainy Hall: 5 Tinderboxes
Old Archives: 10 Tinderboxes
Entrance Hall: 14 Tinderboxes
Archives: 23 Tinderboxes
Wine Cellar: 31 Tinderboxes
Laboratory: 36 Tinderboxes

Part 2: Back Hall (TOTAL 85)

Refinery: 45 Tinderboxes
Cellar Archives: 45 Tinderboxes
Archive Tunnels: 45 Tinderboxes
Back Hall: 47 Tinderboxes
Storage: 72 Tinderboxes
Guest Room: 74 Tinderboxes
Study: 80 Tinderboxes
Machine Room: 85 Tinderboxes

Part 3: Prison/Cistern/Sewer (TOTAL 112)

Prison: 91 Tinderboxes
Prison - Northern Block: 103 Tinderboxes
Cistern - Entrance: 103 Tinderboxes
Control Room: 106 Tinderboxes
Cistern: 108 Tinderboxes
Morgue: 111 Tinderboxes
Sewer: 112 Tinderboxes

Part 4 (Last one): Nave (TOTAL 151)
Nave - Part 1 (Note that few objects will appear after you complete some part of story, and come back to Nave): 122 Tinderboxes
Nave - Part 2 (Note that few objects will appear after you complete some part of story, and come back to Nave): 128 Tinderboxes
Chancel (Note that few objects will appear after you complete Cells, and come back to Chancel): 133 Tinderboxes
Choir Entrance: 135 Tinderboxes
Choir - Main Hall: 144 Tinderboxes
Transept: 148 Tinderboxes
Cells: 151 Tinderboxes
Inner Sanctum: 151 Tinderboxes
Orb Chamber: 151 Tinderboxes

I hope this helps anyone that wants to get the achievement "Illuminatus" and if you find any mistakes, please share them in the comments so I can fix them. Thanks to everyone who found my comment useful and I hope you enjoy the game.

Thank you, this makes it a lot easier. Would be nice if the total amount of tinderboxes for each individual level was listed but other than that its great, much appreciated.

I think a reason some might miss it is because if your steam goes offline it won't count the achievements or achievement progress. And since it won't tell you it's gone offline while you're in a full screen game, you have to happen to look and see in the steam window yourself at the right time, you won't know when it happens.

Every single map is correct, collectible achievements are working and are not broken. Make sure to collect them on normal mode and dont forget to check Nave Part 1, Nave Part 2 and Chancel for few more collectibles after you came back from Cells.

Ok, I rechecked it, every single map is correct, nothing is missed, got both achievements for tinderboxes and notes (for Notes chievo you need to collect also notes in Justine DLC) on my alt acc without any problems. Only reason you didnt got your achievements that i can see only because you missed something or maybe played on Hardcore mode, I dont know if hardcore changes few of the locations and i doesnt think it is. Wasted 6 hours of life, gj missing collectibles and forcing me to check everything
