Body rune

Ironman verdict

At least 9 monsters drop it. The easiest is Giant spider (level 2, 5/128); the best rate is Ghost (Spirit of Summer) (level 50), at 15/128, about 5.9 per kill. You can also make it yourself: it takes 20 Runecrafting and gives 7.5 Runecrafting XP, using Rune essence. There are 2 other recipes below. Other sources include Mystery box (random events), Essence impling, Essence impling jar and Ourania Runecrafting Altar, plus 4 more listed below. Making ten takes 10 × Rune essence and gives 75 Runecrafting XP. Reaching level 20 Runecrafting takes 4,470 XP in total; the Runecrafting calculator counts the actions and materials to any target, and the Runecrafting guide has the Ironman training route. 12 recipes use Body rune, including Apex leather, Black dragon leather and Blue dragon leather. Body rune is available on free-to-play worlds too. 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 3 coins, which is 13 less than the shop price, so buying it to alch does not pay.
