Knife's Edge

Knife's Edge is a passive effect that guarantees every shot will be a critical hit while the player's health is at or below a fixed low threshold. It automatically converts all fired pegs into criticals once the player's remaining HP falls below the specified percentage, allowing high-damage criticals to be produced in clutch, low-health situations.

This effect triggers based solely on the player's current health percentage and requires no additional action. While active it applies to every shot fired, so multi-peg or high-peg-count shots benefit proportionally from the guaranteed criticals. Because the threshold is a percentage, its absolute HP trigger scales with maximum health.

• The effect becomes active when remaining HP is at or below [GUARANTEED_CRIT_HEALTH_THRESHOLD]%.
• All subsequent shots fired while at or below that threshold are treated as critical hits.
• The effect ends as soon as health rises above the threshold; healing or shields that restore HP above the cutoff immediately remove the guaranteed-crit state.
• This relic synergizes with builds that boost critical damage, increase peg count, or rely on powerful finishing shots; it is most valuable in strategies that can safely operate at low HP or that intentionally drop into the threshold to trigger the bonus.
• Because activation depends only on current HP percentage, items that increase max HP raise the absolute HP needed to exit the effect but do not change the threshold percentage itself.
