Slay the Spire - Who Watches The Watcher?

Summary — Slay the Spire: “Who Watches the Watcher?”

The Watcher is a combo- and stance-driven character who toggles Calm and Wrath, builds Mantra toward Divinity, and relies on retained cards and timing for huge burst turns.

Overview / storyline

Slay the Spire is a roguelike deckbuilder: climb floors of the Spire, fight monsters/elites/bosses, collect cards and relics, and build a deck to beat the final boss. This stream focused on the Watcher — a monk-like fighter whose gameplay centers on stance management (Calm and Wrath), Mantra/Divinity, and retained-card setups rather than the Ironclad’s straightforward strength or the Defect’s orb mechanics.

Core gameplay mechanics (Watcher)

• Calm stance
  • Entering Calm gives no immediate effect, but leaving Calm grants +2 energy on exit. This makes Calm → Wrath transitions key for big opening turns.
• Wrath stance
  • Damage dealt is doubled while in Wrath, and damage taken is doubled as well. Best used to kill enemies quickly or in turns where you can avoid retaliation.
• Mantra / Divinity
  • Playing Mantra-building cards accumulates Mantra; reaching the Divinity threshold grants an extremely powerful single-turn buff.
• Retain
  • Many Watcher cards have Retain (they stay in your hand between turns), enabling careful multi-turn setups and combining with energy/miracle effects.
• Starter relic / potion notes
  • Pure Water (starting relic): one free energy once per combat — useful for single-turn burst.
  • Potions like Bottle Lightning (start combat with a skill in hand) or Regen can be worth taking depending on the run.

Notable Watcher cards & short descriptions

• Eruption — enter Wrath (attack-focused).
• Vigilance — gain Block and enter Calm (used to set up Calm exits).
• Fear No Evil — deals damage and returns you to Calm if the enemy was going to attack; useful to finish a Wrath turn safely.
• Flurry of Blows — attack that benefits from stance changes; good for reusable stance-swap damage.
• Crescendo — enter Wrath and often draw cards; upgrading (Crescendo+) was a key smith target in the run for free Wrath transitions.
• Smite / Smite-like cards — high-damage retained attacks, excellent for burst windows.
• Battle Hymn — a power that generates a Smite-like attack every turn.
• Tantrum, Sands of Time — big single cards that can be retained or reshuffled for massive burst.
• Blasphemy — instantly grants Divinity but kills you next turn unless you win immediately — very high risk, high reward.
• Establishment — reduces cost of retained cards (strong synergy with Retain/Mediate effects).
• Ritual Dagger — scales with permanent kills; extremely powerful when boosted.

Strategy & key tips

• Stance management is core
  • Enter Calm before going into Wrath — leaving Calm grants +2 energy for the Wrath turn.
  • Avoid staying in Wrath if enemies will strike you for doubled damage; either kill them that turn or use a card (e.g., Fear No Evil) to exit Wrath safely.
• Use Retain and Miracle (Pure Water) intelligently
  • Hold high-impact retained cards (Smite, Tantrum, Sands of Time) until you have the setup (Miracle + Calm → Wrath).
  • Save Pure Water for the turn you want the big Wrath burst.
• Upgrade priorities
  • Prioritize upgrades that grant free/safer Wrath transitions (e.g., Crescendo+). Upgrading powers and reliable damage sources is valuable.
• Early-game caution
  • The Watcher can be squishy if Wrath is mistimed; early floors often require caution (use Vigilance/Defend to reach setups).
• Powers and draw
  • Powers that put attacks in your hand every turn (Smite generation) and card draw synergize strongly with retained-card plans.
• Example synergies used in the stream
  • Establishment + Meditate: retrieve a card from discard with Meditate, then reduced retained-costs via Establishment makes it cheap the next turn.
  • Crescendo + Pure Water/Miracle: Calm → use Crescendo or Pure Water to leave Calm into Wrath, creating huge-turn windows.
  • Fear No Evil as insurance: does damage and returns you to Calm if the enemy planned to attack, mitigating Wrath’s risk.
• Shop / relic / potion considerations
  • Relics that boost energy or make Miracle-like effects more reliable (e.g., Velvet Choker) are strong for energy-hungry Watcher builds.
  • Potions such as Regen for elites/bosses or Bottle Lightning to guarantee a good opening card are useful.
• Enemy-specific notes
  • Malleable plants that gain block can be annoying — use armor-ignoring or big single-shot damage.
  • Multi-minion elites need area damage/cleave planning.
  • Hexaghost and multi-attack enemies typically require defensive setup or an immediate Wrath burst to kill them before they act.
• Recovery & risk
  • Blasphemy can win instantly (Divinity) but kills you next turn; only use it if you can finish the fight that same round.
  • Safely getting to Divinity (stored Mantra or careful setup) is game-changing but rare.

Walk-through / highlights from the run

• Early fights
  • Streamer experimented with Vigilance/Eruption/Crescendo to demonstrate Calm → Wrath windows and how leaving Calm enables massive Wrath turns.
• Campfires / shops
  • Crescendo was upgraded (Crescendo+) at the smith; potions and relics were purchased to shore up the build.
• Elites & bosses
  • Fought multi-minion elites and bosses (Hexaghost, plant elites, a skeleton elite that summons orbs), highlighting the balance between offense and survival.
• Draw luck and run-ending
  • The streamer discussed several unlucky draws and how card order affected outcomes; the run ultimately ended in a defeat against an elite because the streamer lacked defensive cards in hand to survive a large incoming attack.

Practical quick-play tips

• Get Calm before you go into Wrath — leaving Calm gives +2 energy, making Wrath turns huge.
• Retain matters — pick and keep 1–2 high-impact retained cards (Tantrum, Smite, Sands) for your Wrath turn.
• Make Crescendo (or similar free Wrath-transition) a smith priority for Wrath-centered decks.
• Use Fear No Evil (or similar) as insurance to exit Wrath safely when enemies will strike.
• Consider relics/potions that guarantee opening plays or extra energy (Velvet Choker, Bottle Lightning, Regen).
• Be cautious vs. enemies that punish staying in Wrath; plan to end the fight or return to Calm in the same turn.

• Emphasized the importance of planning turns ahead (two-turn thinking) with the Watcher.
• The stream included a lot of interaction with chat and donors; the streamer explained shop and relic decisions and the reasoning behind smith/upgrades aloud.
