What is Complete Beginner Walkthrough?
A practical original guide to complete beginner walkthrough, organized around actual Slay the Spire 1 decisions and the threats those decisions must solve.
This reference covers gameplay decisions in the original Slay the Spire. Character-specific options and relic synergy can change how useful an item is, so consider your current deck, health, upcoming enemy and available resources before applying a strategy.
When and how to use it
Start with the first section of this walkthrough, apply its sequence in a real run, then adapt the recommendation to the cards, relics and map you actually received.
What to avoid
Do not treat this as a predetermined perfect deck or guaranteed seed; enemy intents, card rewards, potion availability and path options change every run.
Step-by-step guide
Choose a character and read intents
Begin with Ironclad if you want forgiving post-combat healing, but every original character works. The opening hand contains basic attacks and Block. Enemy intent icons show whether enemies are attacking, buffing or using a debuff. Spend energy to prevent significant damage, not to defend on turns when no attack occurs. Look at a fight as a sequence of resource trades: health persists across rooms and energy resets each turn.
Read the first map and choose fights
Act I gives the deck its foundation. Ordinary fights add cards and gold; elite fights are riskier but award relics. Plan a route that reaches a rest site after major danger. A shop is most valuable if you have gold and a specific weakness to fix. Question marks may contain fights or events, so they are not guaranteed rest. The boss portrait at the top of the map signals a known challenge to prepare for.
Prioritize usable cards rather than rarity
Choose early cards that solve immediate damage or defense. A rare Power can be powerful in a long boss fight and nearly useless when a Gremlin Nob rushes you down. Count costly cards and ask whether the next hand can play them. You are allowed to skip card rewards: a weak new card dilutes future draws and may make an important defensive card less likely to appear.
Enter each act with a plan
Act II punishes decks that only attack one enemy; prepare for multi-hit attacks, multiple attackers and debuffs. Act III asks for consistent scaling rather than a single large early turn. Boss rewards and relics should support a plan rather than dictate an arbitrary archetype. Save potions for when they prevent major damage or defeat a dangerous encounter sooner.
Learn from death and pursue the Heart later
A normal Act III victory is a meaningful goal. After unlocking the special ending, Ruby, Emerald and Sapphire Keys open Act IV; each key has an opportunity cost. Review a defeat by identifying which encounter exposed your weakest area: opening damage, sustained Block, card draw, energy or boss scaling. Improve one of those decisions next run instead of copying a full deck list and hoping to draw the same cards.
