⚡ What Supply Line does
Every pet you craft gets bonus base weight: between 0.1 kg and 0.18 kg at the Mule's base weight. The ability text adds "(Max 3 KG)".
Base weight matters because a pet's weight at every age is built from it (weight = Age-1 weight × (age + 10) ÷ 11). An extra 0.1 kg at age 1 is worth almost 4.6 kg by age 500, so a crafted pet gets a permanent head start.
The wiki records two old bugs. Cancelling a craft used to return the pet with the bonus anyway, and Pack Mules from the Trader Event always had a 1.10 kg base weight. Both were fixed.
📈 Pack Mule stats by weight
| Pet weight | Max bonus base weight |
|---|---|
| 1 kg | 0.2 kg |
| 5 kg | 0.28 kg |
| 10 kg | 0.38 kg |
| 25 kg | 0.4 kg |
The top of the bonus range grows 0.02 kg per kilogram and reaches its 0.4 kg cap at only 11 kg, so a light Pack Mule is nearly as good as a heavy one. The table starts at 1 kg for that reason.
