The Defect

An automaton eternally modifying itself to survive. Deploys Orb technology when it must fight.

Playstyle

Mechanical genius who builds orbital engines. Community consensus: fun but underpowered compared to StS1. Relies more on specific cards than other characters. The temporary focus system is preferred over permanent focus by experienced players.

Strengths

0-Cost/Claw builds are most reliable. Temporary focus (Hotfix, Synchronize) is well-designed. Echo Form + 0-cost cards = multiple claws per turn.

Weaknesses

Underpowered overall. Capacitor, Smokestack, Feral are considered weak. Power builds get "too finicky" at high ascensions.

Style

Engine-focused. Prioritize deck cycling and energy. Evoking Ice > brute defense once cycling is established.

Community Tips

Practical advice from high-ascension players

Early game: prioritize damage. By end of Act 1: need protection and block. Don't underestimate Nimble and Dexterity. Chaos and upgraded Fusion are incredible.
