• Cost: 2
• Effect: Shiv. Gain 8 Block.

A cost-2 defense Skill with the Shiv keyword that grants 6 Block (8 upgraded). Block-per-energy is modest, but the Shiv keyword — auto-plays when moved from hand to discard — changes the calculation entirely. In discard-heavy decks, Impunity effectively provides free Block every time it drops. Combines with Sleight of Hand to hand out the Shiv keyword, or Bullet Time to bypass the cost. A Shiv-deck / Discard-deck consideration.

• Shiv lets it auto-play on discard, so it shines in decks that discard frequently.
• Pair with Dagger Throw, Acrobatics, Setup, and other discard effects to dump Impunity for free Block.
• Cost 2 is heavy, but Bullet Time (all 0-cost this turn) lets you play it alongside everything else.
• Sleight of Hand can apply Shiv to other cards and also interacts with Impunity's discard-trigger pattern.
• Because much of the Block lands for free via discards, the low Block-per-cost rarely matters in practice.

• Dagger Throw / Acrobatics: discard effects. Dumping Impunity triggers its Shiv proc for free Block.
• Storm of Steel: discard entire hand. With Impunity in hand, the mass discard delivers massive AoE plus defense.
• Bullet Time: all cards cost 0. Cost-2 Impunity plays freely, thickening defense.
• After Image: 1 Block per card played. Impunity's play adds an extra +1 Block layer.

• Silent Discard Build (S-tier)
