Hilbert's Hotel Catalysts
All 166 run-scoped Catalysts with their full effect text at every level, what each one is bound to, and every Synthesis recipe.
A Catalyst in Hilbert's Hotel is a buff you draft between rooms. Clear a combat room and the game offers you three, each costing a flat amount of the run's own currency; the one you take applies for the rest of that crawl and expires with it. There are 166 of them.
These are not the Reactor Catalysts you equip outside combat. Those are permanent, there are 17, and they slot into a character's Reactor. The two systems share a word and nothing else, which is a genuinely bad piece of naming and the reason this page exists separately.
The three tiers
A Catalyst arrives as one of three things, and knowing which changes how you draft.
Base Catalysts are what the offer screen hands you, 59 of them. Most run from Lv. 1 to Lv. 3, and the level is what the numbers scale on.
Refined Catalysts are the upgrade, 50 of them. A Refined Catalyst is a differently named Catalyst rather than a fourth level: Fuming Sulphur becomes Molten Sulphur, and the 20% proc chance becomes 40%. It replaces the Lv. 1 to Lv. 3 range with a single stronger effect.
Synthesis Catalysts are made from two others, 57 of them, and they are the top of the system. Calcined Copper is Molten Sulphur combined with Fulgurite Copper, and it carries both effects plus a link between them. Every recipe is listed further down.
That structure is the whole strategy of the mode. Taking the strongest-looking card in every offer leaves you holding a spread of unconnected Base Catalysts at the end of a run; committing to one chain early is what gets you to a Synthesis while the fights still matter.
What a Catalyst is bound to
Read the tags before you read the effect. This is where runs are lost.
Character Catalysts (69). Bound to one member of the roster. They rewrite that character's damage profile, usually trading Ultimate damage away for a much larger Skill or Charged Attack, so they are worth a great deal on the character you actually play and nothing at all on the rest.
Attribute Catalysts (20). Keyed to a Reactor Attribute rather than a person. They add bonus damage of that attribute and build its Resonance, so they follow whatever your team is already stacking.
General Catalysts (77). No binding at all. These proc off something anybody can do, a crit, a parry, an Execute, a Tactical Assault, which makes them the safe pick when a run has drifted away from your main character.
A Character Catalyst that reads beautifully is worth nothing if it is bound to a teammate you never tag in, and the draft screen will not stop you taking it.
All 166 Catalysts
A Base and the Refined it becomes sit side by side, so you can read what the upgrade actually buys. Synthesis Catalysts have their own band lower down, because each one merges two Refined from different chains and belongs to neither. Effects shown are the top of each one's own range.
Upgrade chains (49)
Every Base Catalyst that upgrades, and what it turns into. A Refined Catalyst replaces the Lv. 1 to Lv. 3 range with one stronger effect rather than adding a fourth level.

No Catalysts match those filters.
All 57 Synthesis recipes
Every Synthesis Catalyst and the pair it is made from. Both ingredients have to be in hand, so a recipe is a plan for a run rather than something you stumble into.
Where Catalysts come from
- Clearing a combat room is the source. You are shown a choice of three and take one, and most rooms offer a single pick, some two, and a few three.
- Each one costs run currency. Ten against a pool of 295 was the observed price, so a run's budget decides how many of the offers you can actually take.
- They last one run. A Catalyst is drafted inside a crawl and expires with it, the same way Mementos do.
- The higher tiers are built, not drafted. A Refined Catalyst is the upgrade of one you already hold, and a Synthesis Catalyst is made from two of them, which is why a run that commits to one chain early ends up stronger than one that takes the best card in every offer.
Frequently Asked Questions
What is a Catalyst in Hilbert's Hotel?
A Catalyst is a buff you draft between rooms inside a Hilbert's Hotel run. Clearing a combat room offers you a choice of three, each costing run currency, and the one you take applies for the rest of that crawl. There are 166 of them across three tiers, and they expire when the run ends.
How many Hilbert's Hotel Catalysts are there?
There are 166: 59 Base, 50 Refined and 57 Synthesis. This page lists all 166 with their full effect text at every level.
Are Hilbert's Hotel Catalysts the same as Reactor Catalysts?
No. They share a word and nothing else. A Reactor Catalyst is permanent, slots into a character’s own Reactor outside combat and fires on a Tactical Assault; there are 17 of them and they live on the Catalysts page. The ones here are drafted mid-run, apply only to that run, and disappear when the stage ends.
What is a Refined Catalyst?
A Refined Catalyst is the upgrade of a Base one, and it is a differently named Catalyst rather than a fourth level. 50 of the 166 are Refined. Base Catalysts run from Lv. 1 to Lv. 3; a Refined one replaces that whole range with a single stronger effect.
What is a Synthesis Catalyst?
A Synthesis Catalyst is made from two others rather than drafted. There are 57, each combining a specific pair, and every recipe is listed on this page. They are the strongest tier and the reason a run that commits to one chain early beats a run that takes the best-looking card in every offer.
Which Hilbert’s Hotel Catalysts work on any character?
77 of the 166 have no binding at all and proc off something anybody can do: a crit, a parry, an Execute, a Tactical Assault. Another 20 are keyed to a Reactor Attribute rather than a person, so they follow whatever your team already stacks. The remaining 69 are bound to one member of the roster and do nothing on anybody else.
Do Catalysts carry over between Hilbert’s Hotel runs?
No. A Catalyst lasts the run you drafted it in and expires with it, the same way Mementos do. Leaving part-way through and coming back is different: a save and resume drops you at the room you left with everything you were holding.
Every Catalyst effect here: last checked . Values can change as the game updates.
