Burst
Silent · A-tier · Skill · RareDoubles a key Skill for a devastating combo — copies Nightmare, big Poison, or a huge Block card.
Silent Shiv Burst
Silent · Shiv BurstCreate many small attacks, multiply them with Accuracy-style scaling, then finish with burst payoffs.
Ironclad Strength Burst
Ironclad · Strength BurstStack Strength, then convert it into one or two turns of overwhelming attack damage.
Defect
Orb scaling, Focus, and energy burstsDefect turns a small Focus lead into a whole fight plan. Good decks either scale orb output every turn or compress the fight with energy and zero-cost tempo.
Blade Dance
Silent · B-tier · Skill · CommonInstant burst of three Shivs — great with Accuracy and Shiv payoffs, dead weight without them.
Bone Shards
Necrobinder · B-tier · Attack · UncommonA flexible AoE-plus-Block burst when you can spare Osty — great in decks that re-summon him cheaply.
Champ
Act 2 · High danger · HP 440His Block resets every turn — low-output builds can't break through. Stack Poison or save a burst turn.
Darkness
Defect · B-tier · Skill · UncommonCheap Dark-orb generation whose Evoke damage snowballs — the setup for a Multi-Cast burst.
Dredge
Necrobinder · B-tier · Skill · UncommonRecurs your best three cards for a stacked combo turn — powerful setup for a burst finish.
Hyperbeam
Defect · B-tier · Attack · RareHuge AoE burst, but the Focus loss hurts Orb decks — best as a finisher rather than a repeat play.
Impervious
Ironclad · A-tier · Skill · RareThirty Block in one card is a lifesaver against boss burst turns; Exhaust keeps it out of your deck the rest of the fight.
Multi-Cast
Defect · A-tier · Skill · RareDumps all energy into repeated Evokes — a burst finisher that pairs with a charged Lightning or Dark orb.
Nightmare
Silent · A-tier · Skill · RareTriples your best card for a devastating turn — the setup piece behind Silent’s biggest burst combos.
Offering
Ironclad · S-tier · Skill · RareTwo energy and three cards for free is the strongest single-turn burst enabler in the game — HP is a resource here.
Outbreak
Silent · A-tier · Skill · RareA heavy Poison burst that immediately cashes in the stack — expensive, but strong when Accelerant or existing Poison multiplies the payoff.
Phantom Blades
Silent · A-tier · Power · UncommonRetained Shivs plus a big bonus hit — turns a Shiv deck from steady chip into serious burst.
Quadcast
Defect · A-tier · Skill · AncientFour Evokes off one card is a massive burst — pair it with a charged Dark or Lightning orb to delete a target.
Sacrifice
Necrobinder · A-tier · Skill · RareConverts your summon into an enormous burst of Block — a panic button that scales with Osty’s HP.
Second Wind
Ironclad · B-tier · Skill · UncommonBig burst of Block that clears dead Skills — great in Exhaust decks with Feel No Pain and Dark Embrace.
Silent
Poison, shivs, discard, and defenseSilent is strongest when the deck commits early: Poison solves long fights, shivs and Accuracy solve burst turns, and discard/draw keeps the best cards cycling.
Sunder
Defect · B-tier · Attack · UncommonBig hit that refunds itself on a kill — excellent against fodder and for chaining a burst turn.
Tempest
Defect · B-tier · Skill · UncommonDumps all energy into Lightning orbs — a powerful setup card for a Focus-boosted Lightning burst turn.
Thunder
Defect · B-tier · Power · UncommonTurns Lightning Evokes into AoE bursts — strong in a Lightning deck that cycles orbs through Dualcast.
Time’s Up
Necrobinder · A-tier · Attack · RareCashes a huge Doom stack into instant burst — the payoff that closes out Doom decks.
Awakened One
Act 3 · Extreme danger · HP 300Save your potions for Phase 2! Revival puts you under immediate pressure with no time to set up.
Biased Cognition
Defect · A-tier · Power · AncientA huge instant Focus spike that wins short fights outright — the decay only matters in drawn-out ones.
Co-op planning, roles, and troubleshooting
v0.107.1 main · v0.110.0 beta notesCoordinate party jobs, rewards, and version checks so a multiplayer run does not become several isolated solo decks.
Defect Focus Orbs
Defect · Focus OrbsScale Focus and orb slots so Lightning, Frost, and Dark orbs solve the fight passively.
Defect Zero-Cost Tempo
Defect · Zero-Cost TempoChain cheap cards, energy spikes, and recursion to win before the enemy plan stabilizes.
Donu & Deca
Act 3 · Extreme danger · HP 300 / 300Kill Deca first! Letting it keep stacking shields on Donu makes the fight infinite.
Ironclad
Strength, Exhaust, and block scalingIronclad wins by turning HP and cards into permanent combat advantage: Strength makes attacks matter, Exhaust trims the deck, and Barricade-style block engines buy enough time for boss fights.
Necrobinder Countdown Control
Necrobinder · Countdown ControlDelay enemy plans while countdown and graveyard effects line up a lethal future turn.
Regent
Stars, weapon creation, Forge, and card generationRegent is a scaling planner: stars and created weapons create inevitability, while Forge and Prophesize let the deck line up a decisive future turn.
Regent Forge Weapons
Regent · Forge WeaponsForge and weapon creation turn future turns into reliable damage and block packages.
The Corrupt Heart
Act 4 · Extreme danger · HP 750Beat of Death is the deadliest mechanic — every card you play damages YOU. Keep your deck lean; never add junk cards.
The Guardian
Act 1 · Medium danger · HP 240Never use multi-hit attacks in Defensive Mode — Thorns will shred your HP fast.
The Insatiable
Act 2 · Extreme danger · HP 321 / 341 (A8+)Sandpit is an instant-kill timer. If your deck is bloated or cannot draw Frantic Escape on time, normal block will not save you.
