Quick Answer
Defect has 88 cards (29 Attacks, 39 Skills, 20 Powers) built around the unique Orb system. Cards channel Lightning (3+Focus passive damage), Frost (2+Focus passive Block), Dark (accumulates 6 damage per turn until Evoked), Glass (AoE damage that diminishes over time), and Plasma (1 Energy per turn). Focus increases all Orb outputs, making Defect a powerful late-game scaler.

Defect Card FAQ
What are the best Defect cards in Slay the Spire 2?
Top Defect cards: Focus scaling — Defragment, Biased Cognition, Consume; Frost — Glacier, Coolheaded, Chill; Lightning — Electrodynamics, Ball Lightning, Storm; Zero-cost — Claw, Beam Cell. Defragment (Gain 1 Focus) is widely considered one of the best Defect cards because each point of Focus increases all Orb passive and Evoke effects.
How many Defect cards are in Slay the Spire 2?
Defect has 88 unique cards: 4 Basic/Starter, 20 Common, 36 Uncommon, 26 Rare, and 2 Ancient. By type: 29 Attacks, 39 Skills, and 20 Powers.
What are Orb cards in Slay the Spire 2?
Orb cards are Defect-exclusive cards that channel Orbs into Orb slots. There are 5 Orb types: Lightning (deals 3+Focus damage to a random enemy passively each turn), Frost (generates 2+Focus Block passively each turn), Dark (accumulates 6 damage per turn until Evoked for a massive burst), Glass (deals AoE damage that diminishes over time), and Plasma (generates 1 Energy per turn). When a new Orb overfills your slots, the rightmost Orb is Evoked for a stronger effect. Focus increases all Orb passive and Evoke values.
Is Claw a good card in STS2?
Claw is a 0-cost Attack that deals 3 damage and permanently increases ALL Claw damage by 2 for the rest of combat. In dedicated Claw builds with multiple copies and All for One (returns all 0-cost cards from discard to hand), it becomes extremely powerful. However, it requires build-around commitment.
How do Orb slots and Evoke work in Slay the Spire 2?
Defect starts with 3 Orb slots. Channeling fills slots from left to right. When all slots are full and you Channel a new Orb, the rightmost Orb is automatically Evoked (triggering its stronger active effect) to make room. Capacitor adds +2 Orb slots, increasing passive value every turn. Multi-Cast Evokes your rightmost Orb multiple times — devastating with a fully-charged Dark Orb. More slots improve every Orb strategy.
What is the Glass Orb in Slay the Spire 2?
Glass Orbs are new to Slay the Spire 2. They deal Focus-scaled AoE damage that diminishes each turn, filling a niche for crowd control in multi-enemy encounters. Focus increases Glass Orb damage like other Orb types. However, Glass Orbs are not a primary build path — they're useful as supplementary AoE rather than a core win condition.
