Tectonic robe bottom is a tier 90 members item worn in the legs slot for Magic, with a high alchemy value of 300,000 coins. No shop sells Tectonic robe bottom and no monster drops it, so an Ironman makes it: it takes 92 Runecrafting and gives 1,000 Runecrafting XP, using 28 × Tectonic energy and 2 × Stone of binding.

Ironman verdict

Where the materials come from: Tectonic energy (dropped by Vorago (level 10000)); Stone of binding (sold by Bandit Duty Free for 450,000 coins). Making ten takes 280 × Tectonic energy and 20 × Stone of binding and gives 10,000 Runecrafting XP. Reaching level 92 Runecrafting takes 6,517,253 XP in total; the Runecrafting calculator counts the actions and materials to any target, and the Runecrafting guide has the Ironman training route. 10 recipes use Tectonic robe bottom, including Augmented tectonic robe bottom, Elite tectonic robe bottom and Tectonic essence. It is worn in the leg slot at tier 90 as magic gear; compare it with every other piece on the Legs list. Tectonic robe bottom is members-only. It is tradeable on normal accounts, but an Ironman cannot use the Grand Exchange or trade for it, so the sources on this page are the whole list. High Alchemy turns one into 300,000 coins.
