Drafting effects
Drafting effects are effects of rooms, items, constellations, experiments, and any other sources that in some way alter the ordinary drafting process or draft pool. Drafting effects may add or remove floorplans to or from the draft pool, make certain floorplans more likely to be drawn, provide additional options that can be used while choosing a floorplan to draft, or even cause the drafting process to be skipped entirely.
Many drafting effects add a visual indicator of their effect to the drafting interface.
Draft pool manipulation
Several effects alter the draft pool either temporarily or permanently by adding extra floorplans, or by removing floorplans, preventing them from being drafted.
- Additions: Temporary drafting effects, like that of the Pool, can add floorplans for the day, while permanent effects like the Drafting Studio add them indefinitely.
- Duplication: Some effects, like the Chamber of Mirrors, can duplicate existing floorplans. Like with Additions, these duplicates may be temporary or permanent.
- Removal: Some floorplans, like the Freezer, remove themselves to prevent them from being drafted on back-to-back days. Other effects may remove floorplans other than themselves.
Making certain floorplans more common
Many drafting effects have a probabilistic effect on the drafting process by making floorplans of a certain type of quality more likely to be drawn from the draft pool. Multiple such effects can affect the drafting process at once.
Making certain colors more common
These effects cause certain colors of floorplans to be drawn more often. They should not be confused with color-selective drafting.
- Drafting the Greenhouse makes Green Rooms more common today.
- Drafting the Furnace makes Red Rooms more common today.

The Banner of the King power allows a color to be selected each day, which will create an effect making floorplans of that color more common. All seven colors may be chosen.
[Found Floorplan: Treasure Trove] The Royal Scepter provides the same effect if it was picked up today. Selecting the same color with both effects does not stack, though it is possible to make multiple colors more common at once.
Making other types of floorplans more common
- While drafting in the Library, Unusual and Rare floorplans are more common.
[Studio Addition: Solarium] Drafting the Solarium will make Unusual and Rare floorplans more common for the rest of the day, though to a lesser degree than the Library.
- Activating the The Southern Cross at an Observatory will make 4-way floorplans more common today.
- Activating the Draxus, the Dead at an Observatory will make Dead End floorplans more common today. This includes "Dead End" floorplans.
[Luxury item Spoiler: Chronograph] The Chronograph makes Tomorrow Rooms more common while held.
[Contraption Spoiler: Powered Electromagnet] The Powered Electromagnet makes Mechanical Rooms more common while held.
Forced draws
Some effects force a particular floorplan to be drawn, completely overruling the usual process of drawing floorplans in a particular slot.
- The first draft of the game always consists of a Bedroom, a Closet, and a Hallway.
[Upgrade Spoiler: Nook] While drafting in the Reading Nook, the Library is guaranteed to be the third floorplan drawn no matter what other drafting effects are in play.- [Post-Credits Room: Gift Shop] The Gift Shop is guaranteed to be drawn once it has been added for the first time, immediately after reaching Room 46 for the first time.
- [Found Floorplan: Tunnel] The Tunnel is always drawn while drafting in the Tunnel.
Drafting options
Drafting options appear to the side on the drafting interface, and can be chosen after the first three floorplans have been drawn. Many options have identical effects, but come from different sources and may have different costs attached to them. Free options often suppress identical options with an associated cost attached to them while they are available.
Redrawing floorplans
To redraw floorplans is to discard the three floorplans that are currently shown and to draw three new ones from the draft pool. The newly drawn floorplans are drawn via the same process as the initial three floorplans. The three discarded floorplans are filtered out, and are only drawn again if the draft pool starts to become depleted from repeated redraws. There is no limit to how many times floorplans can be redrawn in one draft.
The option to redraw floorplans is a key tool in navigating the random nature of Blue Prince, to the extent that there is a resource item, ivory dice, dedicated to this purpose.
Spoilers Within
This section contains spoilers for all ways to redraw floorplans.
- During any draft, while holding at least one ivory dice, an option appears that redraws floorplans any number of times, at a cost of one die per use.
- While drafting in the Drawing Room, an option appears that redraws floorplans once per draft, at no cost.
- While drafting with at least one gem while there is a Study on the estate, an option appears that redraws floorplans up to eight times per draft, at a cost of one gem per use.
- While both the Drawing Room and Study options are available, the Study's option is suppressed.
- While drafting in the Classroom, an option appears that redraws floorplans as many uses as there are Drafting Rooms in the house, at no cost.
- After activating the Ink Well at an Observatory today, an option appears that redraws floorplans any number of times, at a cost of one star per use.
- If a Paper Crown is owned, an option appears to redraw floorplans if there are no Red Rooms drawn in the round and no redraws have been performed yet.
- While drafting into one of the four corners of the Estate with the Resilience of the Rook power obtained in the Precipice, a Rook option will appear that redraws floorplans up to four times, at no cost.
- The effect of the Crown of the Blueprints is able to redraw floorplans when a red room is drawn, in addition to its other effects of removing the room from the draft pool and giving 1

Rotating floorplans
Some floorplans, specifically L-shape and T-shape floorplans, can be drawn in multiple different orientations depending on which of their doorways is connected to the drafting door. To rotate floorplans is to rotate all currently drawn floorplans with multiple orientations to the next valid orientation. L-shape rooms, which have two possible orientations during the drafting process, are flipped to the other side. T-shape rooms, which have three different orientations, are rotated to the next clockwise orientation, even though the floorplans appear to rotate anticlockwise visually.
All rotation options can be used any number of times in succession, though some have an associated cost. Floorplans can never be rotated so that a doorway points outside of the house. This means that T-shape floorplans can only be rotated while drafting into a central tile, and L-shape floorplans can only be rotated while drafting either to or from a central tile. Some floorplans which would appear to be rotatable, such as the Patio, are not due to unique drafting restrictions. If there are no floorplans drawn which can be rotated in the current position, then the option still appears but can be activated, instead bringing up a message saying that the floorplans cannot currently be rotated.
List of ways to rotate floorplans
There are four ways to rotate floorplans. Only only rotation drafting option can ever appear on the drafting interface at a time; if more than one of the following effects is active at the same time, the uppermost effect takes priority.
- [Studio Addition: Dovecote] While drafting while the Dovecote is one of the three drawn floorplans, an option appears that allows floorplans to be rotated freely. Notably, the Dovecote floorplan can only be drawn in positions where it can be rotated, meaning that this option can always be used.
- While drafting in the Rotunda, an option appears that allows floorplans to be rotated freely.
- While drafting, holding the Ornate Compass, and choosing from the first three floorplans drawn, an option appears that allows floorplans to be rotated freely. Using any effect that redraws floorplans will remove this option for the remainder of the draft.
[Outer Room: Shrine] While drafting while the Blessing of the Dancer is active, an option appears that allows floorplans to be rotated at a cost of one gem per use. As the only rotation option with a cost, it is also the only option for which the direction of the rotation of T-shape rooms matters.

Other drafting options
- While holding the Chronograph after a redraw, an option appears to rewind floorplans back to the previous draw.
- [Outer Room: Shrine] While drafting with the Blessing of the Berry Picker active, an option appears that draws and drafts a random floorplan from the draft pool immediately, disregarding the three drawn floorplans.
Selective drafting
Some effects dramatically alter the drafting process so that it solely draws floorplans of a certain quality or type. Effects of this type usually act like entirely different drafting processes, and may follow their own rules instead of using the draft pool and rarity systems.
Color-selective drafting
Successfully using the Prism Key on a locked door, or drafting from the Secret Passage, will initiate a draft in which all floorplans drawn are a specific color. There are five types of color-selective draft:
- Violet or Bedroom drafts
- Orange or Hallway drafts
- Green or Green Room drafts
- Gold or Shop drafts
- Red or Red Room drafts
There is no way to select Blueprints or Blackprints specifically. While it is ordinarily only possible to perform a color-selective draft from the Secret Passage or a locked door, it is possible to perform a Hallway draft anywhere in the house by way of a particular Prism Key interaction.
Color-selective drafting should not be confused with making floorplans of a certain color more common.
During a color-selective draft, only floorplans of that color can be drawn. These floorplans will be drawn from the draft pool if able. If there are not enough floorplans of that color, or if there is no special floorplan for the first slot, then the draft may draw upon reserve copies of floorplans. These reserve copies may ignore the unique drafting restrictions of those floorplans, though they still obey basic shape placement rules, and may be duplicates of rooms in the estate. Some relatively early-game additions are available for reserve floorplans, even if they are not currently in the draft pool:
- [Secret Room: Morning Room]
- [Studio Addition: Solarium]
- [Studio Addition: Dormitory]
- [Studio Addition: Casino]
These reserve floorplans are drawn separately from the draft pool and will not be drawn again if they are discarded by redrawing floorplans. While drawing, if there are still no valid choices even after considering the reserve floorplans, the draft resorts to showing a "default" floorplan, of which there are three for each color. These floorplans may break the usual rules of drafting by including doorways pointing outside of the house if drafted on an edge or corner. Doorways that point outside the house will appear boarded up with no drafting door, the same as when they are drafted pointing towards the wall of another room.
| Bedrooms | Bedroom | Boudoir | Guest Bedroom |
|---|---|---|---|
| Hallways | Hallway | Passageway | Aquarium |
| Green Rooms | Courtyard | Aquarium | Cloister |
| Shops | Commissary | Kitchen | Locksmith |
| Red Rooms | Gymnasium | Darkroom | Chapel |
- If two different color-selective drafts are attempted at once by using a Prism Key on the Secret Passage door, the Prism Key takes priority, resulting in a Hallway draft.
- Since most Green Rooms and all initial Shops have a gem cost, color-selective drafts of those colors will be frequently unable to find a valid free floorplan for the first slot, instead placing a special floorplan in that slot and waiving its cost.
- Since almost no Hallways are Dead Ends or L-shaped, using a Prism Key in a Hallway to draft in a corner tile will always result in drawing floorplans with doorways that point outside of the house, regardless of the state of the draft pool. (The Secret Passage has drafting restrictions that usually prevent it from doing this.)
- [Upgrade Spoiler: Cloister] If the Cloister is upgraded such that its color changes to no longer be green, Solarium replaces its spot as the default.
Grounds drafting
Spoilers Within
This section contains spoilers for west path.
On the west path in the grounds, a single Outer Room may be drafted. The rules for drafting the Outer Room are very different to drafted in the house:
- The draft pool is not used whatsoever. Consequently, effects that add to or remove from the draft pool, such as the Pool or Repellent, do not affect drafting from the grounds. Instead, a separate "deck" of floorplans is made from the eight Outer Rooms, from which three are drafted.
- Redrawing floorplans causes the previous three to be discarded and a new set of three to be drawn, making it possible to see every Outer Room with two redraws. After the second redraw, previously discarded floorplans may be seen again.
The ability to draft Outer Rooms is unique to drafting from the grounds, as they cannot be drafted inside the house by any means. However, it is possible to draft non-Outer Rooms from the grounds; see Blessing of the Monk and Blessing of the Berry Picker.
Other selective drafts
- The Silver Key results in a draft that exclusively draws floorplans with three or four doorways if able, with one exception. Rooms with two doorways are drawn only if either the draft was performed in a corner or if all rooms with more doorways are depleted or unavailable.
- [Upgrade Spoiler: Cloister] Drafts initiated in the Cloister of Draxus will exclusively draw Dead End floorplans, including "Dead Ends".
Other drafting effects
The Compass adds a high tendancy for drawn floorplans to be oriented with a north door if possible. While drafting northwards with a Compass, T-shape rooms are guaranteed to have a north door. While drafting westwards or eastwards with a Compass, both T-shape and L-shape rooms are highly likely to have a north door, though not guaranteed.
Spoilers Within
This section contains spoilers for the Workshop.
The Compass is the component of two contraptions: the Dowsing Rod and the Powered Electromagnet. When the Compass is used to assemble either contraption, its effect is gained for the rest of the day even if the contraption is lost or never picked up. The Compass' effect is also applied for the whole day if a Compass-based contraption is in Coat Check at the start of the day, even if Coat Check is never drafted.
