There are six hightail lizards around Satori Mountain (-2098, -0329, 0293), besides Hyrule Field and Hyrule Ridge. If you run around aimlessly, you may scare off the lizards, causing them to disappear until you return another time. When approaching an area with lizards, crouch down and approach them slowly. You can equip Stealth armor to conceal your approach.
Buying From Beedle
It’s good news if you don’t want to go around farming for Hightail lizards: Beedle’s Lakeside Stable and South Akkala Stable stocks Hightail lizards for 10 rupees each. You won’t be able to stockpile dozens of lizards with this method, but if you only need a few more for your upgrades, it’s a solid option.
What Are Hightail Lizards Used For in TOTK?
Hightail lizards are mainly used to upgrade the Climbing Gear armor set from level two to level three. Electric Keese wings, Hightail lizards, and rupees are required for this upgrade. Fortunately, the Satori Mountain spot I mentioned above will provide enough lizards for one upgrade. The rest will be available after a few visits to Beedle and a few trips to Beedle.
