Corrosive Draw Build

Build Overview

The Corrosive Draw build pairs Corrosive Wave (3–4 AoE Poison per draw this turn) with heavy-draw cards to stack explosive Poison in a single turn. Play Corrosive Wave then Acrobatics (3–4 draw) and 9–16 AoE Poison lands instantly, with Infectious Blast piling on AoE damage at the same time. With Craftsmanship (refill hand to 6–7) or Setup (redraw the hand), 30–50 Poison stacks in one turn becomes realistic, and Catalyst lets all that Poison tick 2–3 times for crushing damage. Consistency is a little shaky since you need to draw Corrosive Wave, but when it hits, the burst ranks among the best.

Tier: B

Highly reliant on drawing Corrosive Wave, so turns without it feel like a regular Poison build. The silver lining is that Acrobatics and Craftsmanship are valuable on their own, so the deck still functions as an ordinary Poison deck when Corrosive Wave is missing. Retaining Corrosive Wave via Well-Laid Plans lifts consistency dramatically, pushing the build close to Tier A.

Key Cards (required)

• Corrosive Wave: a skill that applies 3–4 AoE Poison per card drawn this turn. The engine of the build. Concentrate draws on the turn you play it.
• Acrobatics: 0-cost, 3–4 draw + 1 discard. The ultimate pair with Corrosive Wave — 9–16 Poison in one card.
• Infectious Blast: 11–14 AoE every 3 Poison applications. Each Corrosive Wave draw fires chained Infectious Blast damage.
• Catalyst: adds extra Poison ticks per turn. Multiplies the Poison mountain built on Corrosive Wave turns, producing exponential total damage.

Candidate Cards

• Craftsmanship: refills the hand to 6–7. Post-Corrosive Wave, a single card applies 18–28 Poison. Absurd combo.
• Backflip: 5–8 Block + 2 draw. After Corrosive Wave, gives 6–8 Poison plus Block in one efficient card.
• Setup: discards the hand and redraws the same number; Exude skill. Redrawing 5 cards after Corrosive Wave adds 15–20 Poison.
• Well-Laid Plans: Retains 1–2 cards at end of turn. Holds Corrosive Wave every turn for stable combo setup.
• Burst: plays the next skill twice (0-cost upgraded). Double Corrosive Wave does not really give two turns of effect, but doubling Poison-application skills after Infectious Blast pushes trigger counts further.
• Deadly Poison: 5–7 Poison. Adds on top of Corrosive Wave Poison to speed up Infectious Blast triggers.
• Noxious Fumes: auto-applies 2–3 AoE Poison at turn start. Keeps Poison accumulating on turns without Corrosive Wave.

Relic Synergies

• Backpack: draw 2 extra cards at start of combat. More opening draws means a higher chance of landing Corrosive Wave on turn 1, starting the combo immediately.
• Twisted Funnel: a Silent-exclusive Poison relic. Meshes perfectly with Corrosive Wave's mass Poison application, boosting accumulation efficiency.
• Snecko Skull: Silent-exclusive. Extra effects on every Poison application — with dozens of Poison applications per turn here, the payoff is huge.
• Spooky Lamp: doubles the effect of the first debuff card played per combat. Doubles Corrosive Wave's first Poison application, accelerating the entire combo.
• Centennial Puzzle: draw 3 cards the first time you lose HP in combat. Those extra draws on a Corrosive Wave turn pile on more Poison.
• Letter Opener: 5 AoE damage every 3 skills played on a turn. Corrosive Wave, Acrobatics, Craftsmanship, Backflip — skill spam is constant, and this reliably adds AoE.
• Chess Piece: draw 1 card each time you play a power. Placing Catalyst, Noxious Fumes, or Well-Laid Plans gives bonus draws, and if Corrosive Wave is active, those draws also apply Poison.

Combat Play

Act 1

Collect multiple Acrobatics to set up Corrosive Wave combos. Ideally land Corrosive Wave early, but if not, play it as a standard Poison build centered on Deadly Poison and Infectious Blast. Slotting Infectious Blast from the start guarantees AoE contribution in hallways with or without Corrosive Wave. Keep the deck thin.

Act 2

Well-Laid Plans lets you Retain Corrosive Wave, dramatically raising consistency. Craftsmanship unlocks the "one-card mega Poison" combo after Corrosive Wave. Catalyst at this stage turns stacked Poison into multi-trigger damage for a huge output jump. One or two Corrosive Wave turns against the Act 2 boss pushes Poison to 30–50, and Catalyst reliably puts you at 60–150 damage per turn.

Act 3

A finished deck can Retain Corrosive Wave every turn and pair it with draw to stack 30–50 Poison per turn. Multiple Infectious Blasts give extraordinary AoE from every Poison application. Stacking multiple Catalysts to tick Poison 4–5 times per turn closes out almost any enemy in a few turns.

Strengths and Weaknesses

Strengths

• Corrosive Wave + Acrobatics/Craftsmanship produces 30–50 Poison in a single turn.
• Combined with Infectious Blast, each Poison application adds AoE damage, giving extraordinary hallway clear.
• Acrobatics and Craftsmanship are generally useful draw cards, so the deck still functions without Corrosive Wave.

Weaknesses

• Relies on drawing the key card (Corrosive Wave); without it, combo power collapses for that turn.
• Corrosive Wave is a turn-limited effect, requiring concentrated draws on that turn — demanding hand management.
