Gollux items can transfer stars to the next tier, saving you billions! Here's how to set it up:

1. Add both items — Add the item you're starring (fodder) AND the item receiving stars
2. Mark the fodder — Check "Is Fodder" on the lower-tier item (e.g., Solid Ring)
3. Set up the receiver — On the higher-tier item (e.g., Superior Ring), check "Gollux", pick the transfer star level (usually 21 or 22), and select your fodder item
