Secrets

Hidden rooms

The first five floors can each generate a hidden room: Mole Stronghold, Woodlands, Library, Wasteland and Rooted Cave. Qliphoth's Temple never rolls one. Finding your first grants the Traveler achievement, so walls are worth bumping from chapter 1 onward.

The Library carries one scripted room on top of the random roll. After the fight with Erma, the Mad Scientist, a secret study sits in the bottom-left corner of the map. Nothing marks it, the room stays invisible until you step into its passage, and inside waits a lore object for the journal.

A hidden room rolls one of five rewards, all equally likely: an EXP chest, a chest of leaf, dice, a Mystic Pot, or a cluster of breakable props (two of them, three when the run has three or more players). Dice arrive singly or in pairs and the leaf chest holds roughly 230 to 280 leaf. The props usually shake out consumables from this set:

• Focus Potion
• Apple Juice
• Nebbiolo’s Stubbornness
• Tempranillo’s Passion
• Ugni Blanc’s Mist
• Malbec’s Depth

A charm can turn up in place of all that, but it is by far the rarest outcome. What the Mystic Pot does is covered under special objects below.

Rare events

Seven events spawn rarely enough that whole runs pass without one. From most to least common: the lucky shrine, the dimensional rift, the obelisk, the blood donation altar, the wandering witch, the double doors and the magic fountain.

The lucky shrine is a straight pick between two statues: the heart adds 6 max HP, the shield adds 4 DEF. The dimensional rift is the portal into the pocket dimension and its sapphire shop, covered in its own section below.

Reading the obelisk grants one random buff: +4 or +7 physical damage, +3 or +6 fire, cold or lightning damage, +3 evasion, +7 DEF, +7% to +12% attack speed, +5 barter, 1 life steal, +4 luck, +3% move speed or 2 dice. Sometimes nothing happens at all.

The blood donation altar trades a third of your current HP for a charm or tablet. A bat always hangs around it, and killing the bat can drop this:

• Oath of the Vampire Lord

The wandering witch is the witch hat merchant on the move: six items at a time from a pool sold nowhere else, and its rock-bottom barter keeps every price low. The full stock is in the witch hat section.

The double doors appear only on floor 3: the gold door opens for 500 leaf, the blue one for 4 sapphires, and either pays out a random reward. The magic fountain appears only on floor 1, and a drink rolls 100 leaf, 200 EXP, two dice, an enemy ambush or nothing. It is the one event on this list that can actively hurt you, so drink with an escape route in mind. Dice from either event feed the reroll system described under special objects.

Special objects

Four interactables do more than hand over a pickup, and each has rules worth knowing before you spend on it.

Dice reroll an item reward you don't like. They drop from hidden rooms, the obelisk and the magic fountain, and several destiny tree nodes raise your starting count, pay dice for boss kills or hand one back whenever you forfeit a reward.

The Mystic Pot rerolls and upgrades charms. Feed it one charm and 50 leaf and it returns a different charm of the same rarity; feed it two of the same rarity and it returns one of a higher rarity. A legend charm only goes in alone, so two legends never merge into anything. Each pot survives eight uses per player, then shatters. Since the single-charm mode is a straight reroll, a pot is also the cheapest reroll station in the game. It shows up as a stage reward, a hidden room roll and the odd merchant room, and it won't open unless you carry at least one charm.

From the Wasteland onward, every safe zone puts a tablet combiner next to the merchant. For 200 leaf it fuses two tablets into one that carries both effects, with overlapping positive and negative tiles summing into a single value. An ingredient that rotates can still be rotated during the fuse, a placement constraint on either ingredient carries over to the result, two conflicting constraints refuse to combine, and the fused tablet can never enter another combiner. Each combiner works once, and you get to name the result.

The fruit skewer stand opens in the safe zone after finishing Kalle's snack side quest, itself a destiny tree unlock. Pick up to six fruits per run, or eight in the Farmer Squirrel costume. Each fruit steers one item set's appearance rate: its level runs from minus two to plus three, every step swings the rate by 50%, and the total is clamped between minus 100% and plus 150%. Picks that roll a sapphire icon also add 20% sapphire gain. The Carrot is the odd one out: a single pick that adds 25% more combo-matching items per combo artifact you hold, up to 75%, and it skips any set whose fruit sits at a negative level.

The pocket dimension shop

Any floor can hide a pocket dimension: the chance is 7% per floor, raised to 10% on runs whose seed is divisible by 10. Inside, first-time purchases permanently unlock the item for the sapphire price listed below; buying an already-unlocked item again costs double. Restocks roll rarity at 54% uncommon, 24% rare and 2% legend, and the Exit tablet only appears once the destiny tree's Tablet node is active. Entering for the first time also grants the "Where the Blue Being Lives" achievement.

The witch hat merchant

The witch hat trades from a fixed 13-item pool (11 charms and 2tablets sold nowhere else), shuffled per encounter, so two witch hats in the same run can carry different stock. Don't attack it: the moment it enters combat it stops trading, empties its stock and flees, and the trade orb breaks. The pool includes the three Tomes of Transmutation, which convert your attacks to the fire, ice or lightning element.

• Cursed LetterCharm
• Diamond BadgeCharm
• Garnet BadgeCharm
• Lunch BoxCharm
• Red MushroomCharm

• Tome of Transmutation - FireCharm
