Coolant

DefectPowerRare
At the start of your turn, gain 2 Block for each unique Orb you have.

At the start of each of your turns it counts the distinct Orb types in your queue and gives 2 Block per type (3 upgraded): two Frost and a Dark is 4 Block, 6 upgraded. The Block is flat, so Dexterity and Frail do not change it. It stacks; a second copy doubles the rate. An empty queue gives nothing.

When to take Coolant

Worth a Rare pick only in variety decks like Chaos or a Frost, Lightning and Dark mix with Capacitor. At three Orb types it wins long Act 2 and 3 fights, but skip it in a one-Orb deck.
