The Silent's strength is in efficiency and volume: superior card draw, fast cycling, and debilitating debuffs that control the pace of every fight. She has no healing mechanic — staying alive early is critical. On Ascension 2+, Ring of the Snake upgrades to Ring of the Drake.


The Sly Keyword (New in STS2)

The Silent's defining new mechanic is Sly: when a card with the Sly keyword is discarded from your hand before end of turn, it plays automatically for free. This rewards discard-heavy strategies and opens a third core archetype alongside Poison and Shivs.

Key Sly cards: SurvivorSurvivor (in the starting deck!), TacticianTactician, Flick-FlackFlick-Flack, HazeHaze, ReflexReflex, UntouchableUntouchable.


Build 1: Shiv Deck

Generate, buff, and spam Shiv cards to deal massive burst damage in rapid succession.

Core Strategy: Stack Shiv generators early, then add AccuracyAccuracy to double all Shiv damage. Use Knife TrapKnife Trap as a late-game finisher — it can generate 15–20 Shivs in a single turn.

Key Cards

How to Win: Find 2–3 copies of AccuracyAccuracy as early as possible — it's the archetype's multiplier. Infinite BladesInfinite Blades upgraded to Innate guarantees a Shiv on Turn 1. Save Knife TrapKnife Trap for boss fights — it plays 15–20 Shivs in one activation, all triggering Accuracy and relic procs. AfterimageAfterimage offsets the low defense of the archetype by generating Block per card played.

Relic Priorities

  • Ninja ScrollNinja Scroll — adds 3 Shivs to your opening hand every combat; an immediate Shiv deck starter.
  • Helical DartHelical Dart — gain 1 Dexterity per Shiv played; provides defensive coverage over many Shivs.
  • Nunchaku / Kunai / Shuriken / Ornamental Fan — all trigger on Shiv spam since Shivs are played cards.

Build 2: Poison Deck

A slow-starting deck that stacks Poison for exponentially scaling passive damage.

Core Strategy: Apply Poison fast with Poisoned StabPoisoned Stab and Deadly PoisonDeadly Poison, then amplify it with AccelerantAccelerant. Stay alive early while Poison ramps.

Key Cards

How to Win: Stack Poison fast in early turns, then use AccelerantAccelerant to supercharge the damage — upgraded Accelerant is one of the highest-impact cards in the game. BurstBurst makes the next Skill play twice, doubling a Deadly Poison or Accelerant. Noxious FumesNoxious Fumes guarantees Poison application each turn, crucial for multi-enemy rooms.

Relic Priorities

  • Twisted FunnelTwisted Funnel — applies 4 Poison to all enemies at combat start; unlocks Bubble Bubble immediately.
  • Snecko SkullSnecko Skull — every application of Poison adds 1 extra stack; transforms every Poison card.
  • Anchor / Horn Cleat / Captain's Wheel — survive turns 1–3 while Poison ramps.

Build 3: Sly Deck

A fast-cycling engine that discards Sly-tagged cards to play them for free and maintain momentum.

Core Strategy: Build a lean deck (12–15 cards) with cheap discard outlets (AcrobaticsAcrobatics, PreparedPrepared, ReflexReflex) and high-value Sly payoffs (TacticianTactician, Flick-FlackFlick-Flack, HazeHaze). Keep discarding to keep the engine running.

Key Cards

How to Win: TacticianTactician is the engine — it refunds Energy when discarded, enabling infinite cycling loops. Tools of the TradeTools of the Trade automates the cycle every turn. Master PlannerMaster Planner converts all non-Sly Skills into Sly cards, dramatically expanding the trigger pool. Add light Poison via HazeHaze for reliable single-target damage alongside the cycle.

Relic Priorities

  • TingshaTingsha — deal 3 damage per discard; turns every cycle trigger into damage.
  • Tough BandagesTough Bandages — gain 3 Block per discard; solves the archetype's defense needs.
  • Nunchaku / Shuriken / Kunai — Sly cards count as played cards, so they still proc these relics each trigger.
