Archetypes & Builds
Orb-Focus Engine
Strategy
Channel orbs, stack Focus, let passive effects win. Safest and most consistent build.
Power Spam
Key Relics
Strategy
Flood the board with Powers. Storm turns every Power into lightning damage.
Claw / 0-Cost Spam
Key Relics
Strategy
Thin deck cycling 0-cost cards. Claw scales with each play. High-risk, high-reward.
Relic Tier List
Run-defining
+3 orb slots. More orbs = more passive value every turn.
+1 Focus at start of combat. Immediate and permanent scaling.
Rightmost orb's passive triggers twice. Double Lightning or Frost value.
Strong synergy
Powers played make a random card cost 0 this turn.
Replaces starter relic: channel 1 Frost at end of turn.
Gain Focus at turn start, lose Focus when taking HP damage.
Situationally good
First Power each combat is played twice.
Gain +1 orb slot every 2 turns.
Common Pitfalls
Ignoring Frost Orbs
criticalOne Cold Snap + Focus changes everything. Frost is the best block engine in the game.
Over-channeling without slots
highChanneling a new orb evicts the oldest. Get Capacitor or slots from relics before stacking orbs.
Taking too many mediocre Powers
mediumNot every Power fits your deck. Heatsinks is dead without Power density. Hello World is slow.
Neglecting card draw
highDefect has weak draw. Prioritize Coolheaded, Skim, Seek, or Compile Driver early.
Claw before it's ready
mediumOne Claw is not a build. Commit to 0-cost cycling or skip it entirely.
