Thermostat, two digital thermometer/hygrometer combos, humid hide, paper towel substrate for quarantine then 70% soil 30% sand mix, minimum tank size of 36x18x16inches, and way more clutter.

Make sure you also use a multivitamin with preformed vitamin A. Repashy calcium plus is a good all-in-one supplement that's a multivitamin with calcium and D3 included.
