Rang S

Lightning Build

Channel Lightning Orbs and amplify with Focus for devastating passive and evoked damage. Electrodynamics makes Lightning evoke hit all enemies—crucial for AoE. Echo Form doubles Defragment, Ball Lightning, or Glacier. Ball Lightning and Cold Snap channel while dealing damage; Defragment and Hot Fix scale everything.

Rang B

Claw Build

Claw has fallen to D tier in expert rankings—it needs many zero-cost cards and Unceasing Top to go infinite. All For One requires drawing zero-cost cards first; Scrape can discard Defragment. Consider Frost or Lightning instead; Claw is situational or meme-tier in STS2.

Frost Build

Stack Frost Orbs with Focus for massive passive Block every turn. Glacier, Coolheaded, Chill, and Defragment form the core; Capacitor adds slots. Hot Fix provides temp Focus; Genetic Algorithm scales block. Slow but extremely safe—Frost plus Focus blocks virtually everything in long fights.

Dark Orb Build

Dark Orbs store damage over time; channel with Darkness or Doom and Gloom, trigger passives, then evoke for massive single-target burst. Darkness upgrade triggers passive twice. Pairs with Defragment for scaling and Recursion or Multi-Cast for multi-evoke. Solves boss damage when Lightning and Frost handle block.

Boss Strategies

BOSSSlime Boss

Lightning Orbs with Electrodynamics deal AoE on evoke—perfect for cleaving both Large Slimes after the split. Channel 2–3 Lightning early, ramp Focus with Defragment or Hot Fix, then evoke for burst. Frost Orbs provide passive block during setup. Boot Sequence blocks 10 innate on turn one; prioritize Defragment and Capacitor in your draft.

BOSSThe Guardian

Frost Orbs shine here—Glacier, Coolheaded, and Chill generate passive Block that neutralizes Fierce Bash and Twin Slam. Defragment and Hot Fix scale both block and damage. Lightning Orbs provide consistent damage through Defensive Mode when the Guardian isn't attacking. Capacitor adds orb slots for more passive value; one Defragment is often enough to outscale.

BOSSHexaghost

Orbs work on autopilot—channel Frost early and focus on blocking. Divider scales off Turn 1 attacks, so avoid over-committing damage. Glacier and Coolheaded build block; Defragment multiplies orb effects. Avoid over-evoking Lightning on turn one; let passive damage tick. Genetic Algorithm and Echo Form scale long fights.

BOSSWorm Boss

The Worm adds status cards; Defect lacks easy exhaust, so status package (Fight Through, Iteration) helps if you have it. Turbo adds Void—use cautiously. Frost plus Focus blocks most damage; Dark Orb or Barrage can solve single-target. Creative AI scales over time if you have setup turns.

BOSSQueen

Queen locks cards in hand; Defect's orb output is mostly passive, so locked attacks matter less. Retain key powers like Defragment and Echo Form before they get locked. Machine Learning helps line up Hot Fix for second-cycle scaling. Glacier and Coolheaded provide consistent block; Dark Orbs with Recursion or Multi-Cast burst when ready.

Pro Tips

Focus multiplies ALL orb effects—Defragment is king; one Defragment is often enough to outscale bosses.

Frost plus Focus equals near-infinite Block in long fights; Glacier and Coolheaded are Defect's strongest defensive tools.

Hot Fix provides 2 temporary Focus for 0 energy—common and extremely strong; loop it in your second deck cycle.

Capacitor and Modded add orb slots; with Focus, more slots mean multiplicative scaling for both block and damage.

Echo Form doubles your best play every turn; prioritize it for Defragment, Glacier, Creative AI, or key attacks.

Don't ignore Frost even in offensive builds—Defect has no healing, and passive block wins long fights.

Darkness solves single-target damage; channel Dark, trigger passives, then evoke for burst. Upgrade triggers twice.

Genetic Algorithm gains block permanently each combat; combine with Echo Form for massive scaling.

Boot Sequence is 0 energy innate 10 block—slam it on turn one to avoid trading HP for setup.

Claw is desperation tier in STS2; Frost and Focus are the primary strategies; All For One needs many zero-cost cards.

Synchronize gives 2 Focus per unique orb type; with Lightning, Frost, Dark, and Glass, it scales massively.

Temp focus from Hot Fix and Focus Strike applies when orbs trigger—orbs don't need Focus at start of turn.
