How to get Royal Sphinx
Reach about 10K Speed and travel to the Desert biome 🏜️. Wait until the Scorpion guardian is asleep, grab the Royal Sphinx Egg from the nest and run back to your pen before you get caught. Nests reset every 5 minutes, and bigger eggs are worth more but make you slower — so bring extra Speed.
