; Spare Ribs
: ''“Put more health in your health.”''

== Overview ==
The '''Spare Ribs''' vending machine dispenses Catastropop’s Bone Broth Cola, granting the player a permanent increase to '''Max HP''' along with an immediate heal equal to the same amount. It’s the only vending machine that permanently upgrades your health pool.

== Mechanics ==
* '''Interact range:''' 16 units (proximity check).  
* '''Prompt:''' ''Press [E] to upgrade max health for {cost}''.  
* '''Interaction time:''' Instant.  
* '''Effect:''' Randomly increases both '''Max HP''' and '''current HP''' by the same amount.  
* '''Audio:''' Plays '''sndBuy''' and '''sndPowerDrink''' on purchase.  

=== Cost ===
* '''Base formula:'''  
  `<code>cost = clamp(25 * (uses + 1), 25, ∞)</code>`  
* '''Rounding:'''  
  `<code>cost = round(cost / 25) * 25</code>` → always a multiple of 25.  
* '''Scaling:'''  
  Cost grows linearly with the number of times the machine has been used.

=== Health Gain ===
* '''Formula:'''  
  `<code>_amount = irandom(uses + luck)</code>`  
* The random gain increases with both '''uses''' (more upgrades bought = higher potential) and the player’s '''Luck''' stat.  
* Both '''Max HP''' and '''current HP''' increase by this rolled amount.

== Strategy ==
* A long-term investment — expensive in early rounds but snowballs with luck.  
* Players running high-luck builds can maximize value from Spare Ribs.  
* Useful before high-round runs or bosses, since permanent HP helps against attrition.  
* Unlike the healing machine, Spare Ribs retains value even if you’re already at full HP.

== Trivia ==
* Internally nicknamed “The Meat Machine” during development.  
* The Bone Broth Cola gag was inspired by early dev discussions about “hipster apocalypse health drinks.”  
* One of the only machines whose benefit scales positively with repeated use rather than diminishing.
