Database 6

Slay the Spire 2 Powers Database

A power page is only useful if it answers three questions fast: what stacks, what falls off, and what actually fires this turn. This database keeps those answers in one place with searchable rules text, trigger families, linked mechanics, and a clean pass over the full live list.

Use This Library

Use the powers page when the room is really a timing and stacking question

This is not a flavor gallery. It is a timing sheet for status icons that routinely bait bad assumptions.

First read

Settle timing and stacking first

Power pages are valuable only when they tell you what stacks, what expires, and which trigger window actually matters this turn. Once the rule is clear, the next page should answer the deck, route, or threshold question built on top of it.

When to use it

When this page helps

Use this page when you need to know what stacks, what clears itself, and what actually fires in the window you care about. It is strongest when the fight is being lost to status timing rather than raw damage totals.

Common misread

Most common misread

The recurring mistake is reading every Counter entry as a timer. Sometimes it is a countdown. Sometimes it is just a live quantity like Doom or Poison. If you collapse those into one rule, the page cannot save you.

Boundary

What this page cannot replace

The powers database is not a full interaction guide for every deck package. It settles the literal timing and stacking read, then hands off to mechanics, cards, or damage tools for the actual tactical decision.

Real use example

Use it when one status read is about to poison the fight

A real line is filtering by trigger family or state, confirming whether a status is a countdown or a live quantity, then jumping to Doom math or the card list once the rules ambiguity is gone.

How to Read the List

The point is not to memorize every state in the game. The point is to see, at a glance, whether a power is persistent, timed, reactive, or part of a larger package you should already be tracking.

Jump to Results Doom Calculator Card Database Relic Database Potions Database

40 entries do not expose a public type tag, and 40 do not expose a stack tag. This page keeps those rows searchable instead of pretending to know more than the data actually says.

198 entriesBuff

Buffs are the long game

Most scaling engines, retention tools, and resource boosts live here. When a run snowballs, a buff usually started it.

43 entriesDebuff

Debuffs create the opening

Weak, Vulnerable, Doom, Poison, and similar states shift the fight by cutting enemy output or opening lethal windows.

199 entriesCounter

Counters are not always timers

A counter can mean remaining turns, charges, raw scaling, or a persistent live value. Read the rules text before assuming it expires.

84 labelsTiming

Timing is the real argument

A power that fires at turn end plays nothing like one that fires after a card or during damage calculation. That timing difference is usually the whole fight.

Database Editorial

Power Lookup Needs Timing Context Or It Becomes Icon Soup

A power page should answer four blunt questions: what kind of state this is, what makes it trigger, whether it stacks cleanly, and whether the text is complete enough to trust without opening a second page. Everything else is decoration.

Why this page matters

Most power mistakes are timing mistakes, not reading mistakes

This database matters because powers look simple on the board and become ugly once timing, stacking, and cleanup enter the room. 281 status entries are only useful if the page separates buff from debuff, trigger family from passive text, and stable states from entries that decrement or clear themselves.

That is why this page groups spotlight packages, trigger windows, and filterable state types before the full list. The goal is not to help you memorize icons. It is to keep you from misplaying a state because the text looked familiar while the timing was completely different.

How this page is verified

Type, stack, trigger, and state flags come from the current power dataset

This page is wired to the live power dataset and icon manifest. Type labels, stack behavior, hook methods, related powers, placeholder flags, self-decrement markers, and self-removal markers all come from the same normalized source instead of being inferred ad hoc in the template.

That verification boundary is important. If a power exposes no public hook list, the page leaves it passive or unspecified rather than inventing a trigger family. That is slower on the ego, but much safer for a real database page.

Hook families are derived from the exposed hook methods, not from theme guesswork.
Placeholder text is marked openly so the page does not fake full certainty.
Related power chips are there to expose packages, not to imply identical timing.

What actually matters

Trigger family and stack behavior do more work than the icon name

When a fight gets messy, the fastest useful read is trigger family first. Turn-start engines, card-play reactions, damage modifiers, and passive rules solve completely different problems even when the icon bar makes them all look like one giant blur. That is why trigger buckets sit above the result list.

Stack behavior is the second real divider. Counter does not automatically mean timer. Single does not mean weak. Non-stacking does not mean irrelevant. The important question is whether the number compounds, refreshes, or simply sits there until some other rule clears it.

Use trigger family when the question is "when does this matter?"
Use stack behavior when the question is "what happens if the state is applied again?"
Use state flags when the question is whether the power persists, decrements, or self-clears.

Common mistakes / traps

The page is trying to stop a few very predictable lies

The first lie is treating Counter as shorthand for duration. Sometimes it is. Sometimes it is just a live value like Doom, Poison, Strength, or some other number that matters without behaving like a countdown at all. The page keeps that distinction explicit because the game punishes the lazy assumption.

The second lie is reading an unspecified tag as missing value. Unspecified on this page means the current data does not expose that label cleanly. That is a database honesty problem, not a gameplay verdict. The correct move is to keep the row searchable, not to guess.

Do not read every Counter entry as a timer.
Do not assume unspecified means weak, hidden, or incomplete in gameplay terms.
Do not confuse related powers with one shared trigger order.

Power Packages Worth Knowing

Most runs are not decided by one isolated status icon. They are decided by packages of powers that pull in the same direction. These quick clusters let you jump straight to the parts of the list that matter.

6 linked powersDoom line

Doom engines and payoff

When a Necrobinder line works, these are usually the pieces pushing the number over the top or cashing it into defense.

6 linked powersAttack math

Attack pressure and debuff math

If a turn lives or dies on clean damage math, these are the statuses you keep checking.

6 linked powersBlock shell

Block retention and scaling

These powers turn defense from a one-turn patch into something that actually carries a fight.

5 linked powersOrb control

Orb and Focus packages

Defect turns get much cleaner once you can see which powers are scaling the orb shell and which are just noise.

Trigger Map

Where Powers Usually Fire

Trigger family matters because timing mistakes lose turns. Start-of-turn engines, on-play effects, and damage modifiers solve different problems even when their text looks similar.

95 powersTurn timing

Turn-start and turn-end engines

These are the powers that care about upkeep, countdowns, or end-of-turn resolution.

65 powersCard play

Card-play reactions

These reward, punish, or reshape what happens when a card gets played.

57 powersDamage

Damage modifiers and punish windows

If a power changes the math mid-hit, it usually lands here.

15 powersBlock

These powers modify block gain, preservation, or block loss.

FAQ

Common Questions

A few answers players keep needing when a fight turns into a pile of icons.

What does “Unspecified” mean on this page?

A small slice of entries does not expose a public buff, debuff, or stack tag in the current rules data. They are still searchable by name and rules text, but the type badge stays Unspecified instead of guessing.

Why do some powers show hook timing and others do not?

Some powers expose clear combat hooks such as turn start, card played, or damage modification. Others only expose stable rules text, so this page treats them as passive entries instead of inventing timing that is not surfaced.

Does a power with Counter always expire?

No. Counter means the amount matters. Sometimes that amount is remaining turns, but sometimes it is just a live value such as Strength, Poison, or Doom.

Can I use this page to find Doom support powers quickly?

Yes. Use the Doom spotlight at the top, or search for Doom, Melancholy, Shroud, Despair, Countdown, or No Escape to jump straight to the relevant package.
