Reflux Storage adds one beautifully cursed item: a portable reflux tank that slowly fills while you carry it, then converts that stored pressure into a vertical burp jump.
Keep Reflux Storage in your inventory, hotbar, or an optional Curios belt/charm slot. It passively charges over time, storing up to 8000 mB of reflux. Right-click the item, or bind the Use Reflux Storage key, to spend stored reflux and launch upward.
Burp power ranges from 1 to 20. Higher power launches harder and costs more reflux.
The item texture changes as it fills, with five visible charge states: 0%, 25%, 50%, 75%, and 100%. The durability bar also shows stored reflux.

Custom burp sounds are split into weak, medium, and strong tiers, plus an empty sound when you do not have enough reflux for the selected power.
Reflux Storage is crafted with rotten flesh, sugar, and a bucket.
