Too Many Words about Slay the Spire 2, Part II of ∞
My win rate is up slightly, probably due more to a balance patch than any mindfulness on my part.
Remember, the four fundamental questions you should be asking yourself are:
- How will I attack?
- How will I block?
- How will I do all-out-attack (“deal with multiple enemies.”)
- How will I scale?
This article deals with the last question. “Scaling, or ‘Why Furnace is a desperation pick.'”
Things I’m rethinking (from the Prior Article)
- I’m slightly less enamored of Leafy Poultice, particularly on Necrobinder (with her low Max HP dropping it further means rests have limited value). Similarly I’m experimenting more with Precarious Sheers, particularly if the Act I map has an early rest, because that cancels the current HP loss and removing two starters is a big deal …. long term.
- I feel like I’ve been over-valuing gold. Card removes are more expensive in StS 2. It’s true you have less shot at a Pandora’s Box (which removes all your strikes and defends); but many Ancient Rewards / Artifacts effectively let you remove big chunks of your deck (or improve them enough to be worthwhile), which counterfeits the store’s “remove a card” option. Because of that, I’ve started looking at Cursed Pearl with a much more jaundiced eye. Yes, it might let you snowball, but if it doesn’t …
- Stone Humidifier (“Gain 5 Max HP when you rest”) is also downgraded, because it does nothing for the early fights. You really need to have an extra rest prior to your elite and hope that the Max HP helps. I had a string of runs where I took this and was not quite strong enough to deal with my first elite, even with delaying it.
- Nutritious Oyster (“Gain 11 Max HP”) provides the Max HP now, so is probably a better choice unless you have a rest-heavy first act.
- This does confirm that Neow’s Talisman (upgrade a strike and defend) is actually good, which was my guess. It probably saves at least ~3-6 HP in every fight up for most of Act I. (And putting Spiral on an upgraded defend in that early event is a big deal)
- I didn’t mention Phial Holster in the last article (as it was new and I’d only picked it a few times). It gives you two potions and an extra potion slot. This is generally solid, it lets you burn an early potion or two and might let you high-roll into a much earlier elite fight, and the extra slot will likely be useful all game (particularly if you must hang onto a potion or two to deal with a hard elite/boss … now you can still gain and play other potions).
(Many of the examples/explanations below are simplified and not dealing with corner cases.)
Understanding Scaling — Kinetic vs Potential Scaling
I won my low ascension Regent runs grabbing Furnace, a power that gives 4 Forge1 a turn. It seemed comparable to Noxious Fumes, a power that adds 2 poison a turn. But that was shallow thinking, and at higher ascensions it failed hard. It took me a while to unpack why, but there are multiple reasons.
The first is that Noxious Fumes is “Play and Forget.” It does 2 damage, then, 3, 4, 5, 6 etc2. With Forge you also have to play the Sovereign Blade to do any damage. Your sword will be worth 14, 18, 22, etc … but attacking with it costs two mana per attack; then you have to wait and get it back, which also means one less other card in your deck. It costs time and card draw.
Noxious Fumes is active from next turn it’s played … doing damage each turn (but starting smaller). Furnace enbiggens your sword, damage requires further costs. I’ll talk more about Forge below, but the point is that Furnace is passive scaling … If you got a second Noxious Fumes, your numbers and damage would go up, but a second Furnace just makes your potential damage go up.
I don’t love this passive/active terminology, perhaps Poison is “complete” and Forge is Incremental? Or “Potential” vs “Kinetic” is best? Kinetic scaling does actual damage. Potential Scaling might do damage down the line.
But that’s not the only issue
Understanding Scaling — Linear vs Geometric Scaling
Consider Inflame. +2 Strength, once. All attacks do (at least) two more3. It’s a perfectly find card, and may help through early elites and bosses. In theory its potential scaling, but in practice it activates pretty fast. Ironclad is usually playing attacks, so boom. Three attacks a turn (say), means six extra damage a turn. That’s OK. But it doesn’t grow. Noxious Fumes starts off small but gets bigger over time.
But if you double something, it gets bigger much faster. Voltaic channels a lightning Orb for every Lightning Orb already channeled. Play it 5 times (even without any other lightning) and you channel 1,2,4,8,16. A geometric progression. If you have even another orb or two played each time through the deck (like Zap) the number can get ridiculous fast (depending on card order). Voltaic can cause 500 damage on it’s own. Inflame requires 250 attacks. A linear progression. If you added a second inflame your deck would be more reliable. A second voltaic would be a grotesque win.
(Again, I don’t love the terms; perhaps “Additive vs Multiplicative” scaling might be better).
Any card that doubles (or halves) deserves a close look. Colossus blocks, but also halves the damage vulnerable opponents inflict.
There are some other types of geometric scaling built into the game:
- All out Attack
- Any enchantment (etc) that adds “Replay” to a card is literally doubling (or tripling) the card. Hidden Gem can be a great purchase, even though replay is being applied to a random card. It’s just that strong and as your deck gets stronger cards it will proportionally scale.
Back to Furnace, and Scaling vs Big Impact Now
Putting it all together, I was treating Furnace like a scaling card, but it’s the worst kind of scaling — linear (+4 to the swords damage …), and potential ( … when you play the sword). Its much closer to Inflame than Noxious Fumes. It has a place, but that place is providing a bit of extra damage when you are low, against not-particularly fast opponents. It absolutely can make the difference in the Act I boss fight … linear scaling is usually enough.
It just won’t win the game, and the opportunity cost of having it take up a valuable card draw (and mana if you play it) may outweigh that in many fights. And often the damage output it does provide is completely inferior to many other options.
Compare Furnace to Wrought in War4. If you play Furnace, next turn you can play your sword for 14. If you play Wrought in War, you can play your sword this turn for 17, plus the 7 you already did. WiW converts 3 mana into 24 damage, a respectable first damage card. That’s its role, with a smidge of linear scaling each further time through the deck. Now granted, if you play Furnace and wait 5 turns, you’ll do more damage, but that’s an eternity in a hallway fight (unless you can consistently block for huge numbers each turn). If you play The Smith (“Forge 30”) and then your sword, you do 40 damage now (for 3 mana and some stars).
The Big Number is much better than scaling in almost all fights. But … you can make The Smith multiplicative by playing it via Decisions Decisions, which plays a skill three times. Now on the turn you play them, your sword hits for a hundred, which would take Furnace 23 turns! (Or you can play it each time it comes through the deck, and if you play your sword each time, it’s a bit multiplicative).
Yes, those cards require a star economy, and are rare, etc. But the point is that the numbers matter, not just the type of growth.
Comparing Forge to Vigor
So I’m not particularly happy to take Furnace. It’s a “I need more damage and haven’t seen great cards” pick. But I’m pleased to grab a Prep Time (“4 Vigor at the start of your turn”) as Regent. Why? Because Vigor can be multiplicative; Regent has lots of targets for multiplication. If you sit and block, you can get 8, 12 or more vigor built up; Build up stars, a card like Stardust (which is an X cost attack, but X is stars, not mana) or Heavenly Drill can quickly grow. Furnace is +4 damage a turn, but even a moderate growth in star economy can turn each point of vigor into 10 or 20 hits, and both numbers can grow each turn …. Geometric, not linear.
You can totally win a Regent run by playing only a single attack. Play two powers Prep Time (+4 Vigor a turn) and Genesis (+2 stars a turn), through out block, and wait for a Stardust to do something like 5 (base damage) + 12 (3 turns vigor) times 20 (stars). As a bonus, you can enchant it to do double damage (or +8 vigor first time played). Prep Time gives you a corner stone you can latch onto; and with a few more pieces (and a lot of block) you have your scaling.
Furnace comes nowhere close.
Redeeming Forge
But Forging can. Summon Forth forges 8 (a reasonable number) …. and puts the sword back in your hand. If your deck was only Summon Forths, you could attack in the following pattern. 18, 26, 34, 42. You gain damage faster and play it more often. Not quite geometric, but much faster linear damage. If you play the Parry power (or two), you now suddenly get damage and block each time you play your sovereign blade. You aren’t multiplying damage exactly, but you are doing two important things (damage and block) each time you play your sword.
Bulwark is a perfectly fine “Block 13 for 2 mana” card … that also forges (10!). I grab it as an early block card, but the damage boost is nice.
The point: Don’t grab a Furnace; get a scaling engine via the following path (or something similar):
- On an early floor I grab a Wrought in War, if no better damage card is offered (“How Will I Attack?“). As mentioned above, it is “24 damage for 3 mana.”
- Grab Bulwark for block (“How will I block?”); but it also forges. Now if I play it and Wrought in War, my Sovereign Blade hits for 27 and I can hold it until it ends the fight (or I have a turn I’m not being attacked).
- At this point, I might get Summon Forth or Parry or Seeking Edge as a multiplier … to (play your sword more often, block as well as attack, or hit all enemies, respectively). All are multipliers in a way, and Seeking Edge answers “How will I handle multiple enemies?“.
- Now there are actual multipliers … Sword Sage makes the sword hit twice (but raises its cost). Conqueror only forges three, but doubles damage that turn. And don’t forget artifact multipliers like Pen Nib5.
- Ideally I’ll also grab a Charge or Begone … to trim the mediocre cards (like basic strikes) out of my deck so that I can play the better cards multiple times (if necessary). (The Chapel strategy from Dominion). Multiplication by division.
Each card answers at least one question other than scaling in the first few steps, attack or block. The initial forge on the cards isnt’t the focus of the card, but a “Yes, and …” The forge provides a path for scaling that comes later. (Similar to how an early silent poison may be meant to handle the first boss, but can also provide the entry way for further scaling).
I’m attacking and blocking; a card or two big enough to handle early hallway fights (or mid-game hallway minions) while incidentally building a linear scaling engine via Forge. Then I’ll only need a card or two (hopefully) to make that a geometric engine … or a big enough linear engine to compensate. Furnace doesn’t do any of that.
Now, I’m not saying Furnace is pointless. If I’ve only seen block cards (or am worried about Lagavulin Matriarch, or know I’ll need to scale while paying for Soul Fysh’s beckons), I might pick a Furnace … as a specific use for a fight. Not for scaling. Sometimes you just don’t get great choices and have to make do … but having taken a Furnace I now now that there might be some synergy with more Forge cards … if they appear.
Writing these as I think I have things interesting to say … so part III whenever.
Update — I realized that the above questions are also missing “How can I make my deck set up faster?” (Sometimes also called ‘Velocity’) and I need to ask that question more often to myself.
- A quick Primer on ‘Forge’ and ‘Vigor’ — Forge X works as follows. If you don’t have a Sovereign Blade, it creates it (in your hand). The blade costs 2 to play, and is retained between turns. The blade’s damage starts at 10 prior to the first forge and is increased (for this combat) by X. (Once you have a sword, Forge X simply increases the swords damage but does not return it to your hand). Vigor X means your next attack (only) does +x damage (per hit), and then the Vigor is spent.
︎ - Poison automatically decreases at the end of each turn so +2 means net +1 each turn once the enemy is poisoned.
︎ - With multi-attacks or X-cost attacks (like Sword Boomerang / Whirlwind) the bonus may apply multiple times per attack.
︎ - Attack 7, Forge 7.
︎ - In multi-player you can also play Hammer Time to let each team-mate forge when you do!
