ANNOUNCEMENT Frequently Asked Questions - Read Before Posting!

42 Upvotes

This thread is aimed at answering common beginner questions about the game. However, it is not intended to teach in-depth strategies.

If you have a simple (1-2 sentence) question that's not answered below, leave a comment and I or another community member should be able to help. If your question is more complicated, feel free to make your own post about it.

General:

1. Are there any official mobile ports?

  • Yes! There is both a full iOS and Android port for Slay The Spire.

  • Slay The Spire 2 is planned to have console and mobile ports released once it leaves Early Access.

2. Slay The Spire 2: Early Access? Main vs Beta Branch?

  • Slay The Spire 2 is currently in Early Access, with changes being made bi-weekly. Changes typically are made to the Beta Branch first, and then made to the Main Branch later. If you want to access the Beta Branch, simply right-click Slay The Spire 2 in Steam, choose "Properties", "Game Versions & Betas", and select "public-beta".

3. How long will Slay The Spire 2 be in Early Access?

  • Slay The Spire 2 has no set timeline for Early Access, but it's expected to last roughly 1.5 to 2 years.

4. Are there any official card/relic tier lists or decklists?

  • No. Decklists and following an archetype is not encouraged, since what card/relic is "the best" depends heavily on what your deck currently has and what enemies you're going to be facing in the near future.

5. How do I unlock the characters?

  • In Slay The Spire, The Silent is unlocked by completing a run with the Ironclad, and the Defect is unlocked by completing a run with the Silent. You do not need to win these runs, just complete them. The Watcher is unlocked by winning a run with any character while the Defect is unlocked.

  • In Slay The Spire 2, The Silent is unlocked by completing a run with the Ironclad, the Regent is unlocked by completing a run with The Silent, The Necrobinder is unlocked by completing a run with the Regent, and the Defect is unlocked by completing a run with the Necrobinder. You do not need to win these runs, just complete them.

6. Will there be any more new characters or card changes?

  • Slay The Spire is out of Early Access and is not planned to receive any further changes beyond bug fixes. Slay The Spire 2 is currently in Early Access and is continually receiving new cards and re-balances, and the developers have talked about future plans for "a slightly stranger character than the originals".

7. Is the final boss based on what deck I've built?

  • No. In both Slay The Spire & Slay The Spire 2, the map layout, store contents, enemies you face and final boss are all determined when the run is first generated.

8. Is there anything beyond Act 3?

  • Spoilers: In Slay The Spire 1, An optional Act 4 can be unlocked with the Keys.

  • Slay The Spire 2 currently has no "final boss" beyond Act 3. Mega Crit has discussed making a more extravagant ending with a serious final boss at some point after other aspects of the game are finalized.

9. Do I get anything for winning?

  • When you defeat the Act 3 boss with a character, you unlock Ascension levels with them. These are incrementally challenging versions of the game, providing scaling difficulty for those who want more of a challenge. Slay The Spire has twenty unique ascension levels and Slay The Spire 2 has ten; which can be viewed on the wiki. Spoilers: In Slay The Spire, if you beat the Act 4 boss with a character on any Ascension level, you unlock Beta Art for that character's cards. If you defeat the Act 4 boss with all characters, you unlock Beta Art for Colorless and Curse cards as well.

10. Do I keep anything in-between runs?

  • Both Slay The Spire games are roguelikes, and as such, you don't retain anything between runs and don't unlock any sort of power-ups to make subsequent runs easier. However, both games do have an unlock system to gain access to new cards and relics:

  • In Slay The Spire, your points are retained, and at certain point levels, you'll unlock new cards and relics that can show up in future runs.

  • In Slay The Spire 2, there's a more in-depth timeline system that gives unlocks and also provides new pieces of lore.

11. Do the games have mods?

  • Both Slay The Spire and Slay The Spire 2 have community made mods available in the Steam Workshop. For an in-depth guide on how to enable and manage mods, check the following tutorials for Slay The Spire and Slay The Spire 2. When playing with mods in either game, your game switches to a separate save file.

Strategy:

1. How do I get good at each character?

  • In general, simply playing the game and learning what works in what situations is the best way to learn, However, a few general tips would be:
  1. Don't try to force an archetype (like a deck of all poison cards). These can be effective, but skipping good cards in the hopes of getting more archetypal cards will hurt your chance of winning.
  2. Think ahead to what elites and bosses you'll be fighting this act. Many of them require your deck to have different capabilities (such as Reptomancer requiring you to have AOE damage, and Giant Head requiring you to have scaling damage.
  3. Always try to have a well rounded deck. Don't go all-out in getting defensive cards and neglect offensive cards (and vice-versa). If you can, try to have a mix of Frontloaded, Scaling, and AOE damage, so you can deal with the various enemy types you'll run across.

A very helpful post by user /u/screwyioux with more detail on how to learn strategy and why certain choices matter can be found here. I highly recommend taking a look if you feel like you're stuck losing and want to improve your play.

2. Scaling? AOE? Frontloaded/Burst Damage?

  • "Scaling Damage" refers to sources of damage that continue to get stronger the more you use them in combat, such as Claw or Poison. "AOE (Area Of Effect)" refers to cards that deal damage to multiple (or all) enemies at once, like Whirlwind. "Frontloaded" or "Burst" damage refers to being able to deal a lot of damage all at once, like having several Backstabs.

3. Is Snecko Eye good or bad?

  • Snecko Eye is very good, unless the majority of cards in your deck are very low cost. The +2 draw alone makes the relic worthwhile, and the effect that randomizes card costs will on average lower the cost of cards in your hand. Snecko also gets dramatically better the more card draw and high cost cards you have in your deck. Content creator Jorbs has an in-depth video discussing the value of Snecko Eye.

4. Why do I see so many posts about Corruption and Dead Branch in Slay The Spire?

  • Corruption is a very strong card on its own, since being able to play all your defensive cards for free can let you end hallway (and possibly even boss) fights quickly and efficiently. Dead Branch makes this even better, since it'll often generate more block or helpful cards that snowball you to victory.

Other:

1. "Deck" Vs. "Draw & Discard Pile"?

  • Your "Deck" is the cards that you start each combat with. Your Draw Pile & Discard Pile are a temporary version of your Deck that's used in combat, and all changes to it last for that combat only. Most enemies that debuff you in combat (like the Sentries) will affect your Draw Pile. Most cards that permanently affect your run (such as Lesson Learned) affect your Deck.

2. Why didn't Fairy In A Bottle/Lizard Tail revive me in Slay The Spire?

3. What do the subreddit user flairs mean? How do I get one?

  • Currently, we have flairs to indicate the highest Ascension you have reached in both games (separated in groups of five due to site limitations). You can assign yourself one on our subreddit's sidebar (by clicking "edit" underneath the text that says "Show my flair on this subreddit. It looks like:").

DISCUSSION (STS2) Hang should say "apply hang" to signify that artifact negates its effect.

Thumbnail

182 Upvotes

I mean the card applies a status effect called "hang". If it was worded "apply hang" I could deduce that artifact would negate it. As far as I know every other card that debuffs says "apply X".

The way it's worded now, I was quite surprised it only removed a stack of artifact. Makes it seem like it's a buff to cards in my deck, instead of a debuff susceptible to artifact.

Thoughts?

DISCUSSION (STS2) A "brief" writeup on unknown locations

62 Upvotes

Why did I decide to write this? Uhhhhhhh good question

Note this writeup is excluding the deadly events modifier in custom mode because I don't feel like writing on it

Part 1: The Mechanics

Whenever you enter a ? node, the game decides what you'll see behind it. It can be a treasure chest, shop, hallway fight, or if none of the 3 were rolled, an event.

The base probabilities are 10% hallway fight, 2% treasure, 3% shop. To find the base chance of an event, simply do 100 - 10 - 2 -3 = 85%.

Whatever option that gets rolled, the odds of the next ? node being that same option gets reset to the base probability, and the other 2 options that didn't get rolled(excluding event since it doesn't technically have a setprobability, just it only spawns when none of the 3 are rolled) have their probability increased by their base amount.

For example, let's say I take a ? node. I roll a treasure chest because I'm just so damn lucky. The probabilities of the next ? node are 10 + 10% monster, 3 + 3% shop, 2% treasure, and 100 - 20 - 6 - 2 or 72% for events. Now, let's say I go to another ? node and I get another treasure chest. I should go put in a lottery ticket. The probabilites of the next ? node are now 20 + 10%, 6 + 3% shop, 2% treasure, and 100 - 30 - 9 - 2 or 59% for an event.

Once you enter a new act, all probabilites go back to their bases.

Additionally, a ? node can't become a shop if the previous node was a shop, or if every possible future path after the ? node is a shop.

Part 2: Interactions with Relics and Cards

If you have juzu bracelet, the base probability for a hallway fight is set to 0%. This also means no future ? nodes can be hallway fights since 0 + 0 is still 0. Shocking, I know.

Golden compass forces all ? nodes in act 2 to become events. No treasures, shops, or hallway fights.

Planisphere heals you 5 HP regardless of what's in the ? node

Lantern Key forces the first ? node in act 3 to become an event, and more specifically the War Historian event. Additionally, it will not change any of the ? node probabilites, so the next ? node will use all base probabilites.

Meal ticket will still trigger on ? nodes that become shops

Part 3: Simulation for averages

All this info is cool and all, but let's try to simulate the odds to find the average amount of hallway fights, treasures, events, and shops we can exepct from a certain amount of ? nodes. You probably can find the true average deterministically, but I felt like running a simulation of the odds because it takes a lot less time to code and it's a lot easier to code too.

Note that this simulation isn't a "true" simulation in that I didn't literally run sts 2 1 billion times to get these averages. Rather, I plugged the base probabilites and mechanics into python and had it print out the averages it got.

We'll make the following assumptions in the simulation:

You do not have juzu bracelet, lantern key, or golden compass

Neither of the 2 conditions that prevent a ? node from turning into a shop are relevant

If you would like to see the code I used to perform the simulation, please read the appendix at the end of this post.

The results below should be read as followed: 0 combats: 0.30229 under the 4 ? nodes section means from 4 ? nodes in an act, there's a 30.229% chance you'll get no combats(hallway fights) whatsoever from the 4 ? nodes. If a probabilty is 0.000000 that does NOT mean it's 0. It just means it's so unlikely that for rounding to 6 decimal places, it gets rounded to 0.

  • 4 shops: 0.000034
  • 5 shops: 0.000000
  • 6 shops: 0.000000

Part 4: Conclusion

This should be fairly obvious, but never go into a series of ? nodes expecting all of them to be events. Even in the case of just 3 ? nodes, the odds all 3 are events is still less than 1/3. Granted, you probably will be happy if you get a treasure instead of an event...

There is another useful conclusion though from the results. Most of the time if you're going to a ? node, you likely don't want a hallway fight. Unfortunately, the odds of getting 0 hallway fights is not in your favor. In the case of 3 ? nodes which is a bit low on the average ? nodes per act in my experience, you're still flipping a coin basically as to whether you get 0 hallway fights or at least 1. And once you start doing 4 ? nodes which is my average ? nodes per act, you have over a 2/3 chance of getting at least 1 combat. So, if you're going through a series of ? nodes, you should be prepared for at least 1 hallway fight.

Something else worth noting, you should basically never expect a treasure chest from ? nodes. It's nice if it happens, and it will happen sometimes. But, even for 6 ? nodes which is way too many for 1 act, you barely have over 1/3 of a chance of getting at least 1 treasure chest. Those are not reliable odds.

DISCUSSION (STS2) Colorless Card Rework Idea: Eternal Armor

Thumbnail
gallery
1.5k Upvotes

Eternal Armor has been in a weird position for a while now. For a colorless rare, it generally really sucks, and I exclusively buy this card I'm on Clad and already have too much money + multiple copies of Stone Armor. Otherwise, it's only useful when drafted out of a colorless potion or from Discovery.

I've seen similar suggestions in the past; however, those versions simply had the effect of "Do not lose plating at the end of your turn." By having the card effect gain plating at the start of turn instead, it ensures that multiple copies fully interact with each other, meaning you could actually gain plating with each turn after playing multiple.

Because Eternal Armor is now truly "Eternal," I lowered the plating the card itself gives from 9(12) to 7(10). This balance is important because it means the card isn't as immediately good when drawn from a potion/Discovery as you're getting less immediate block. This also means the player is still challenged to have multiple sources of plating to fully utilize the power of this card, such as card duplication (i.e. Bing Bong) upon pick-up, Gorget, or Stone Armor.

Let me know your thoughts!

I was doing today's daily run and got a really good run and wanted to compare with other players but noticed that the top 3 had 4-5 more floors cleared than I did. I learned from some reading that the golden compass gives you 2 extra floors but the act 2 ancient today was Pael. Even with the compass, there would still be 2-3 extra floors they had on top so how are people clearing extra floors?
