Lamp being lit immediately stops sanity drain from darkness and allows it to recover if too low.Дaniel starts the game at 100% Sanity and 100% Health.Д®dit: Thanks for the corrections. Amnesia: The Dark Descent, developed on a shoestring budget by five Swedes, is a rare game that outshines (or rather, out-scares) the high-end, high-budget, triple-A titles that so often lay claim. Drains for a second even after putting away lamp so no cheating by rapidly 'cycling' the lamp. <25% - Health status changes to Barely conscious.'Д % - Daniel goes into the fertilizer business. Start the game and then save as soon as you can. <50% - Health status changes to 'A wound is bleeding quite badly.' Daniel's movement speed begins to slow below this point at a rate of 0.5% speed loss for every additional 1% health lost. Create a New Profile (lets call it Daniel for this guide) 3. Noticeably faster than sanity regeneration. <75% - Health status changes to 'A few cuts and bruises.'ДҐ2% - Slowly heals to this point when below it.

Sanity is then set to 37%.Д®very 8 Seconds of darkness drops Sanity by 1%. Below this point the camera will get worsening motion blur and a heavier 'mouse acceleration' effect as sanity lowers further.Д % - Ears ring, 'pass out' (POV goes near floor) for several seconds, and then gets back up. <50% - Sanity status changes to 'Head is pounding and hands are shakeing.'Дў0% - The first time this is reached the hint message about low sanity will appear.

An alternative to this video you can use to gather all collectables in the game, are the Maps the Amnesia Wiki has for each location, including coloured markings for every item and interactable, both collectable and story-related.

<75% - Sanity status changes to 'A slight headache.'ДҐ1% - Slowly rises to this point when below it and not being drained. The Dark Descent: Illuminatus + Master Archivist Video Guide Credit to Mudbill for the video. Didn't see this info on the wiki so I'm just sharing this for any interested in how the game works.

Played this when it first came out but I didn't really understand how sanity worked then, so when replaying it now I did some quick testing. Going through some old spooky games and this was one of them.
