Specifically, it says that the room is in the west wing of the house and that it\u2019s a tribute to her childhood home in Eraja \u2014 the kingdom to the south (based on other clues around the estate). This means that <strong>you can only draft Her Ladyship\u2019s Chamber on the left side of the house and from a door facing south.<\/strong><\/p>\n<p class=\"has-text-align-none\">You can do a few things to help you draft Her Ladyship\u2019s Chamber beyond the layout of the estate:<\/p>\n<ul class=\"wp-block-list\">\n<li>Collect some<strong> Ivory Dice<\/strong> for the rerolls<\/li>\n<li>Draft the <strong>Study<\/strong> and collect a bunch of <strong>gems<\/strong>, again, for rerolls<\/li>\n<li>Solve the <a href=\"https:\/\/www.polygon.com\/blue-prince-guides\/558159\/chess-piece-puzzle-piece-power-choose\">chess puzzle<\/a>, pick the <strong>Banner of the King<\/strong>, and then select bedrooms (purple)<\/li>\n<li>If you\u2019ve hit <strong>50 stars<\/strong>, you can find the <strong>Inkwell constellation<\/strong> in the Observatory that lets you spend stars to redraw rooms<\/li>\n<\/ul>\n<p class=\"has-text-align-none\">Getting the room is only the first part of the problem, though. You\u2019ll also need to get the <strong>Diary Key<\/strong>.<\/p>\n<hr class=\"wp-block-separator has-alpha-channel-opacity\" \/>\n<h2 class=\"wp-block-heading\" id=\"where-to-find-the-diary-key-in-blue-prince\"><strong>Where to find <\/strong>the Diary Key in Blue Prince<\/h2>\n<p class=\"has-text-align-none\">Even if you manage to draft Her Ladyship\u2019s Chambers, you\u2019ll still need to unlock the diary. The Diary Key requires it\u2019s own quest to find. First, you\u2019ll need either a <strong>Burning Glass<\/strong> or a <strong>Torch<\/strong>.<\/p>\n<ul class=\"wp-block-list\">\n<li>For the Self-Ignited Torch, you\u2019ll have to solve the chess puzzle, you can select the <strong>Mantle of the Knight<\/strong> to add the <strong>Armory<\/strong> to your draft pool. That will let you buy a <strong>Self-Ignited Torch<\/strong>.<\/li>\n<li>For the <strong>Burning Glass<\/strong>, you\u2019ll need to find a <strong>Magnifying Glass<\/strong> and a <strong>Metal Detector<\/strong>, and then draft the <strong>Workshop<\/strong>. That will let you combine them to craft the <strong>Burning Glass<\/strong>.<\/li>\n<\/ul>\n<p class=\"has-text-align-none\">Once you have either of those items, it\u2019s probably safest to store it in the Coat Check until\u2026<\/p>\n<p class=\"has-text-align-none\">Next, you need to draft the <strong><a href=\"https:\/\/www.polygon.com\/blue-prince-guides\/560301\/tomb-puzzle-solution-angel-statue-order-how-to-solve\" data-type=\"link\" data-id=\"https:\/\/www.polygon.com\/blue-prince-guides\/560301\/tomb-puzzle-solution-angel-statue-order-how-to-solve\">Tomb<\/a><\/strong> as your Outer Room. You\u2019ve probably already been here to solve the <a href=\"https:\/\/www.polygon.com\/blue-prince-guides\/560301\/tomb-puzzle-solution-angel-statue-order-how-to-solve\">Tomb puzzle<\/a> and gain access to the Reservoir.<\/p>\n<p><img decoding=\"async\" src=\"https:\/\/arcader.org\/wp-content\/uploads\/2025\/04\/how-to-unlock-her-ladyships-diary-in-blue-prince-1.jpg\" alt=\"Blue Prince Tomb map\" title=\"Blue Prince Tomb map\" data-has-syndication-rights=\"1\" data-caption=\"\" data-portal-copyright=\"Image: Dogubomb\/Raw Fury via Polygon\" \/><\/p>\n<p class=\"has-text-align-none\">This time, though, you\u2019re looking for pairs of <strong>ruby-encrusted candlesticks<\/strong>. When you use the Torch or the Burning Glass on them, a secret passage will open.<\/p>\n<p class=\"has-text-align-none\">There are two pairs of candlesticks in the Tomb. The first pair is immediately left of the main entrance. This secret panel only reveals a small table with an <strong><a href=\"https:\/\/www.polygon.com\/blue-prince-guides\/562523\/upgrade-disk-locations-where-to-find-all-how-change\">Upgrade Disk<\/a><\/strong> and some other goodies.<\/p>\n<p><img decoding=\"async\" src=\"https:\/\/arcader.org\/wp-content\/uploads\/2025\/04\/how-to-unlock-her-ladyships-diary-in-blue-prince-2.jpg\" alt=\"Blue Prince secret passage opening behind a pair of ruby-encrusted candlesticks\" title=\"Blue Prince secret passage opening behind a pair of ruby-encrusted candlesticks\" data-has-syndication-rights=\"1\" data-caption=\"\" data-portal-copyright=\"Image: Dogubomb\/Raw Fury via Polygon\" \/><\/p>\n<p class=\"has-text-align-none\">At the back of the Tomb, between the statues of <strong>Joya <\/strong>(chef\u2019s hat) and <strong>Rynna<\/strong> (flat-brimmed hat), you\u2019ll find another pair in an alcove. These candles reveal a secret entrance to Lady Epsen\u2019s coffin.<\/p>\n<p><img decoding=\"async\" src=\"https:\/\/arcader.org\/wp-content\/uploads\/2025\/04\/how-to-unlock-her-ladyships-diary-in-blue-prince-3.jpg\" alt=\"Blue Prince Diary Key location\" title=\"Blue Prince Diary Key location\" data-has-syndication-rights=\"1\" data-caption=\"\" data-portal-copyright=\"Image: Dogubomb\/Raw Fury via Polygon\" \/><\/p>\n<p class=\"has-text-align-none\">Behind the photo on top of the coffin, you\u2019ll find Lady Epsen\u2019s <strong>Diary Key<\/strong>.<\/p>\n<p class=\"has-text-align-none\">Drop the key off in the Coat Check, and then wait until you draft Her Ladyship\u2019s Chamber again so you can open the diary.<\/p>\n<hr class=\"wp-block-separator has-alpha-channel-opacity\" \/>\n<h2 class=\"wp-block-heading\" id=\"what-clues-are-in-lady-epsen-s-diary-in-blue-prince\"><strong>What clues are in Lady Epsen\u2019s Diary in Blue Prince?<\/strong><\/h2>\n<p class=\"has-text-align-none\">For the most part, Lady Epsen\u2019s Diary is about sleeping in various bedrooms. This does apply to Simon, too \u2014 if you <strong>call it a day<\/strong> in the bedrooms, you\u2019ll get the effects described in the diary.<\/p>\n<p><img decoding=\"async\" src=\"https:\/\/arcader.org\/wp-content\/uploads\/2025\/04\/how-to-unlock-her-ladyships-diary-in-blue-prince-4.jpg\" alt=\"Blue Prince Lady Epsen\u2019s Diary final page\" title=\"Blue Prince Lady Epsen\u2019s Diary final page\" data-has-syndication-rights=\"1\" data-caption=\"\" data-portal-copyright=\"Image: Dogubomb\/Raw Fury via Polygon\" \/><\/p>\n<p class=\"has-text-align-none\">The most important part, though, is on the very last page.
