Knight Cap

Knight Cap is a relic that heals the player at the end of combat if the player still has Armor active. It was introduced in early Beta development and was added to the main game during Early Access. The relic's behavior checks for any remaining Armor (called Ballwark/装甲/보호막 in various localizations) after a fight, and if Armor is present it restores a fixed amount of HP equal to the relic's value.

The relic's effective heal amount changed during version history. In v0.9.01 the relic was introduced with a larger heal, and by v1.0 the reward was rebalanced to restore 2 max HP (reduced from 4 HP in earlier builds). The exact numeric placeholder appears in game files as {[KNIGHT_CAP]} and is resolved by the current build to the relic's heal value.

Practical notes and interactions:

• The heal only triggers if any Armor remains at the end of combat; temporary Armor that expires before the end of the fight does not count.
• The relic is most effective in decks or builds that generate persistent Armor or that finish fights without having that Armor broken by enemy damage.
• Combine with Armor-generating cards, items, or synergies that increase the chance to end battles with Armor intact to maximize value.
• The relic rewards defensive play and can offset damage taken across a run by converting maintained Armor into recurring small heals.
• The name is a pun on the phrase "nighty-night," reflecting a lighthearted naming convention.
