Blur

Blur is an uncommon Silent skill that grants 5 Block that is not lost at the end of the turn for 1 Energy. Normally Block resets to zero at the start of each new turn, but Blur's Block persists into the following turn, effectively stacking protective layers over multiple turns. A single Blur each turn accumulates 5 Block indefinitely; two copies stack 10 Block per turn, and so on.

Blur is the backbone of the Silent's Block-stacking strategy. With multiple Blur copies and a fast cycling deck, you can accumulate hundreds of Block over several turns and become effectively immortal against most enemies. It synergizes with any card or relic that benefits from high Block totals, and because it doesn't require other specific cards to function, it's consistent. Upgraded, the Block value increases to 8, which accelerates the stacking speed considerably. Multiple upgraded Blurs are a core wincon for defensive Silent builds.
