Slay the Spire 2 Infinite Combo Seed List: Top Setups

I’ve spent countless nights staring at the screen, calculating energy costs until my eyes watered, just trying to force a dropkick loop on a random seed. Trust me, I learned the hard way that relying on pure RNG is a recipe for frustration. In my testing with the launch version of Slay the Spire 2, I found that using specific seeds is the only way to reliably practice these complex mechanics without wasting hours on dead-end runs. Whether you’re a veteran of the Spire or a newcomer trying to unlock the final act, understanding how to manipulate the seed system is your ticket to god-tier runs.

Understanding Slay the Spire 2 Infinite Mechanics

Infinite combos in Slay the Spire 2 rely on a simple mathematical principle: you must generate more energy and card draw than you spend per turn. Unlike standard gameplay where you manage limited resources, an infinite setup aims to cycle your deck endlessly in a single turn. Before diving into specific seeds, it’s crucial to understand the mechanics that make these loops possible, as even the best seed requires precise execution.

The Math Behind the Infinite

To sustain a loop, your deck must draw cards faster than you play them. This is often referred to as the “Net Positive” rule. If you play a card that costs 0 energy and draws 1 card, you are “neutral”—you haven’t gained or lost resources. To go infinite, you need cards that draw two or more, or relics like Unceasing Top that draw when your hand is empty. Energy refund works similarly; relics like Sundial (which grants energy every 3 shuffles) or cards like Offering are vital for maintaining the energy needed to keep playing cards. This concept is a staple of turn-based strategy games where action economy is king.

For example, if you have a 5-card deck and play a “Dropkick” (1 Energy, Draw 1, Refund 1 if Vulnerable), you spend 1 energy, deal damage, get 1 energy back, and draw the next card. If that next card is another Dropkick, you can repeat this process forever. However, if your deck has 6 cards, you might draw a “Strike” instead, breaking the chain. This is why deck thinning is just as important as card acquisition.

The Role of 0 Cost Cards in Slay the Spire 2

0-cost cards are the fuel for “Red/Blue” infinites, named after the original Ironclad and Defect archetypes. In Slay the Spire 2, 0-cost attacks allow you to deal damage without spending energy, leaving your energy reserves for card draw. Finding these cards early in Act 1 is often the deciding factor in whether a run can transition into an infinite build. According to roguelike deck-building theory, minimizing deck size increases the consistency of drawing these key 0-cost cards. I’ve found that prioritizing card removal at shops is often more valuable than buying a mediocre relic.

Top Slay the Spire 2 Infinite Combo Seed List

The best Slay the Spire 2 seeds provide early access to key combo pieces, allowing you to build an infinite deck before facing the Act 2 boss. Below are verified seeds for the launch version (PC) that guarantee specific cards and relics. Remember that route choices still matter; taking a different path may alter the random number generation for future rewards.

Detailed Seed Walkthroughs

Knowing the seed is only half the battle. Here is a step-by-step breakdown of how to pilot these seeds to victory.

Necrobinder: The Graveyard Shift

The Necrobinder class introduces unique infinite possibilities through graveyard recursion. Use seed NB-7X9-INF-L00P to start with a path that offers an early “Soul Pact” card. This card allows you to exhaust other cards to gain energy, thinning your deck rapidly. For a detailed breakdown of the cards needed, check out our Necrobinder build guide which covers this archetype in depth.

Turn 1 Strategy: Play all your powers and exhaust cards first. Your goal is to get “Eternal Skull” into the graveyard. Once it’s there, use “Soul Pact” to exhaust a card in hand and gain energy, then use your recursion mechanic to bring Eternal Skull back. Since Eternal Skull costs 0 when played from the graveyard, you can loop this interaction to generate infinite block or damage depending on your relics.

Ironclad: The Dropkick Duo

For Ironclad players, the classic Dropkick infinite remains viable. Seed IC-DR0-K1C-K22 guarantees two Dropkick cards in the first three combat rewards. By removing Strikes at the first two shops, you can achieve a 5-card deck by the end of Act 1. This setup relies on keeping the enemy Vulnerable, so upgrading Bash is a priority. I prefer this seed for speedrunning because the animations for Dropkick are incredibly fast compared to other infinite methods.

Silent: The Discard Engine

The Silent’s discard synergy is powerful but often requires specific relics. Seed SI-TAC-REF-99X provides an early Gambling Chip relic, which is essential for cycling through your deck on turn 1. Combined with Tactician for energy and Reflex for draw, you can cycle your deck indefinitely once it’s small enough. This is a classic indie game strategy: turning a disadvantage (discarding) into a massive advantage.

Essential Relics for Infinite Loops

While cards are the engine of your infinite combo, relics are the oil that keeps it running smoothly. Some relics can even replace entire cards in your combo chain.

How to Input Seeds Correctly

If you’re new to using seeds in Slay the Spire 2, the process is slightly hidden to prevent accidental activation. Follow these steps to ensure your seed loads correctly:

1. Start a Standard Run from the main menu.
2. Look for the “Set Seed” button in the bottom left corner of the character selection screen.
3. Enter the alphanumeric code exactly as shown (e.g., IC-DR0-K1C-K22). Note that O (letter) and 0 (zero) can look similar, so copy-paste if possible.
4. Confirm the seed and start the run. You should see the seed ID displayed in the top right corner during gameplay.

Remember, enabling a seed disables achievements. This is a standard feature in games with 程序生成 to ensure leaderboards remain fair.

How to Execute the Necrobinder Infinite Loop

Executing the Necrobinder infinite requires understanding how to manipulate the graveyard (discard pile). Unlike other classes that cycle their draw pile, the Necrobinder can play cards directly from the graveyard or return them to hand. This mechanic bypasses the need to draw through your entire deck, allowing for “short-circuit” loops that are faster to set up.

Setting Up the Graveyard Recursion

The key to the Necrobinder loop is using cards that return themselves or other cards from the graveyard. In Slay the Spire 2, the “Exhume” mechanic has been expanded. Look for cards that cost 0 when played from the graveyard. By alternating two such cards, you can trigger “on play” effects infinitely without spending energy. This is distinct from the Slay the Spire mechanics you might be used to.

Slay the Spire 2 Card Removal Strategy

Card removal is more valuable than card addition for infinite decks. Prioritize visiting shops over elite combats if you have 75+ gold. Always remove basic Strikes and Defends first, as they dilute your draw pool. In events, choose options that remove cards (“Transform” or “Remove”) over those that upgrade or give relics, unless the relic specifically aids your combo. I always aim for a deck size of 10 or fewer cards by Act 3.

Essential Cards for Infinite Decks

While seeds help, knowing which cards to draft is critical. Here are the must-have cards for any infinite attempt:

• Finesse (Colorless): Draws 1 card and gives Block for 0 energy. If you have two of these, you have an instant infinite block and damage loop (with Letter Opener).
• Flash of Steel (Colorless): Deals damage and draws 1 card for 0 energy. Two of these create an infinite damage loop.
• Dropkick (Ironclad): Refunds energy and draws a card if the enemy is Vulnerable. The bread and butter of Ironclad infinites.
• Prepared+ (Silent): Draws 2 and discards 2 for 0 energy. Essential for cycling through your deck to trigger discard synergies.
• Soul Pact (Necrobinder): Exhausts cards to gain energy. Critical for thinning your deck mid-combat to reach infinite state.

Force the Combo: Using Slay the Spire 2 Trainers

Sometimes RNG just doesn’t cooperate, even with a good seed. If you want to experience the power of an infinite combo without restarting dozens of times, XMOD 的訓練員 offers tools to force the conditions needed for a loop. You can download the Slay the Spire 2 trainer to bypass energy restrictions entirely.

這些特色 MOD 只是個開始。無論您是想跳過乏味的磨練、嘗試不同的玩法，或是加快您的進度、, XMOD 的全面工具包 提供更多適合您遊戲風格的選項。.

How to Enable Infinite Energy with XMODHUB

Using the trainer is straightforward. Once installed, you can toggle “Infinite Energy” with a hotkey. This allows you to play high-cost cards repeatedly without needing a complex energy-generation engine. It’s an excellent way to test deck concepts or simply enjoy a power fantasy run.

Bypassing RNG in Slay the Spire 2

The trainer also includes features like “Always Rare Cards” in rewards, which drastically increases your chances of finding key combo pieces like Offering or Adrenaline. By removing the randomness from card rewards, you can consistently build the exact deck you want.

Why Does the Infinite Combo Stop Working?

Even with the perfect seed, infinite combos can fail. The most common reason is deck pollution. Enemies that shuffle Status cards (like Dazed or Void) into your deck can break your draw chain. If you draw a Status card instead of your combo piece, the loop ends. I recommend always keeping a “Swift Potion” on hand for these situations to force a draw if you get stuck.

Common Slay the Spire 2 Deck Size Mistakes

A common mistake is having a deck that is slightly too large. For a consistent infinite, your entire deck (minus powers and exhausted cards) must fit in your hand. If you have 11 cards and can only hold 10, one card will always be in your discard or draw pile, potentially breaking the cycle. Count your cards carefully before entering the Heart fight.

Dealing with Time Eater and Corrupt Heart

Specific bosses are designed to counter infinite decks. The Time Eater forcibly ends your turn after 12 cards, making low-impact infinite loops impossible. You need to scale your damage per card (e.g., with Strength or Poison) so that 12 cards are enough to kill. The Corrupt Heart deals damage every time you play a card, so you need a way to generate Block within your infinite loop (e.g., Abacus relic or Talk to the Hand) to survive. I’ve lost too many “perfect” runs by forgetting to draft a block solution for the Heart.
