Coolant

Rainbow

Rainbow immediately channels three unique orb types (Lightning, Frost, and Dark), instantly providing a high floor for Coolant's turn-start block generation. This synergy allows the player to reach maximum block efficiency with a single card play.

Capacitor

Increasing orb slots is essential for maximizing this card's potential, as it allows the Defect to hold additional unique types like Plasma or Glass alongside the standard set. More slots directly increase the maximum block ceiling Coolant can reach each turn.

Compile Driver

Both cards utilize the 'unique orb' mechanic, rewarding the player for maintaining a diverse orb tray. While Coolant provides the necessary defense, Compile Driver provides the massive card draw needed to cycle into more powers and orb generators.

Echo Form

Playing Coolant twice doubles the block gained per unique orb, creating a massive defensive engine that triggers automatically at the start of every turn. This allows the player to ignore traditional block skills and focus entirely on offensive scaling.

Data Disk

While Coolant provides flat block, the Frost orbs required to trigger its unique count scale with Focus. Data Disk provides early Focus to ensure the Frost orbs in a diverse tray are contributing significant block alongside Coolant's passive effect.
