• Type: Skill

• Rarity: Event-only (Colorless)
• Effect: Double your current Block.

Upgraded

• Cost: 1
• Effect: Double your current Block.

S-tier scaling card for block-focused decks. The effect is simple — double current Block — but combined with Barricade it has unbounded scaling potential. Entrench at 20 Block gives 40, another cast gives 80, exponential. Upgraded drops it to cost 1 which drastically improves play flow. At the Junk Pile event it's a top-priority pick alongside Enlightenment. It becomes a dead card in decks with no way to generate Block, but with even minimal defensive cards it works in any deck.

Sequence matters: generate Block first with defensive cards, then play Entrench. With 0 Block it does nothing, so within the same turn get Block on the field before playing it. Barricade carries Block into the next turn, so residual Block from the previous turn also gets doubled. Cost 2 (pre-upgrade) is heavy, so pair with Enlightenment or Corruption (skills cost 0) to lighten the load. Target Echo Form's double trigger to multiply Block x4, creating a wall-like defense. On boss fights, spend 1-2 turns stacking sufficient Block, then shift remaining turns to pure offense.

• Barricade: textbook combo. Stacking Block every turn while doubling with Entrench builds an unbreakable wall.
• Body Slam: deals damage equal to Block. Entrench-doubled Block translates directly into damage output.
• Corruption: skills cost 0, making Entrench free. You can also spam 0-cost defensive cards to stack Block fast.
• Echo Form: double trigger means Block x4. 15 Block becomes 60.
• Relax: get 15 Block, then Entrench to 30. Also secures next turn's resources.
• Calipers (Relic): Block only decays by 15 at turn end instead of fully resetting. Entrench-stacked Block carries over more effectively.
