I figured as much, at least with the Invoice I know I didn't investigate the wine; the rest were rather cryptic in their purpose, after clearing the map of all enemies loot and mini-events and there's nothing else it's either it's the exit or the sublevel entrance. I also collected a few necklaces that I'm not sure what they open D:

Hi FilliesAreBest, those are quest based items for the same level where you found them. If they stayed in your inventory when you left the level, most probably is because you didn´t do the quest.

There are a few items (quest items, I suppose) that I picked up on my thief run that I am unsure of their purpose and were binned in the storage box. I think one or two may have been used for level transition purpose, but some I don't know what their 'function was'. Items include: Invoice of sale (think this one had something to do with the level with wine caches), rusty crowbar, shroud of nephre-ka. There was more that was related to opening the Desert sublevel.

thank you for listening.
have a nice day!

Thanks for the quick answer. Yeah, you are mentioning the exclusive items for each playable character. We only included in the list the items that drop from chests and altars, as they had hidden properties but, you are right, and we should include those items exclusive for each character. We will work on it. Thanks for telling us.

During my playthroughs for each character I discovered some items missing here. For example, for Ghoul there are "Gold pocket watch" which from my judgment works somewhat like the Tiki Idol. Then "Pocket watch from Mom" which increases life amount.
"Rubber boots" and "Lab goggles" for the Professor. I start seeing a trend of class-specific items not being present. From experiments, I couldn't find difference between Lab Goggles and Eye of Hydra in eyesight but Eye is clearly better.
"Noden's Needles" and "Ancestral mask" are witch-only items.
Same for Thief and Detective gear like "Ammunition belt".
hope it helps.

Hi Storm Raider, we will check about Noden's Needles. You also say that there are many things missing. Could you be more specific?

Thanks in advance.

Why are Noden's Needles not on the list?
In fact, if this is the official list, why are so many things missing?
I can't seem to find any guides or information on this game anywhere on the net.
The only help is from the author in the random comments in discussions, guide section and official youtube channel.

Hi, thanks for updating the table, I can confirm that the information is much more correct. However, there are still some items that I've never seen in the game even though I've completed it and visited every known secret. The items are:

Cthugha's displeasure
He is the Gate
He is the Key
Hypnos' Rejection
Ithaqua's enmity
Lengian Amber Lens
Lengian Ruby Lens
Shabbith-Ka's rancour
Ubbo-Sathla's animus
Ubbo-Sathla's displeasure
Xexanoth's Hetradoxy
Yig's odium
Yululun's thread

Can you check if they are actually included in the final version of the game? If so, can you say how they are obtained? Thanks!

Dear all, thanks a lot for your comments and help. Sadly, the initial information that we had for this table was old, and different to the actual stats of the items, which were changed during the last updates.

Good news is, that we have updated the table with the most updated information, and added some missing items.
