Ironman verdict

Law rune is a free-to-play item. Other players trade it, but an Ironman cannot use the Grand Exchange or trade, so you get your own. We list 9 monsters, 6 shops, 3 recipes and 8 other sources for it.

The easiest way is to buy it: the cheapest of the shops that stock it is Magic Guild Store (Runes and Staves) in Wizards' Guild, at 240 coins each. You can also make it with 54 Runecraft from Pure essence at a law altar. Each one made gives 9.5 Runecraft XP. That is the lowest-level of its 3 recipes. If you would rather kill for it, the lowest-level monster that drops it is Revenant imp (level 7), at 1/605, about one in 605 kills. The best rate is from Guardian Drake (level 376): 10/93, 25–50 at a time. The 9 monsters we list with a combat level range from level 7 to 741. It also comes from 8 other sources, such as Mystery box and Crystal chest. It is on the hard clue scroll reward table, so every hard clue you complete is a chance at it.

The material you can buy or make: Pure essence, made with 64 Mining.

Bosses we cover that drop it: Zulrah, Zalcano and Phantom Muspah. Shops stock it in 5 places, including Wizards' Guild, Lunar Isle, Ape Atoll and Prifddinas.

It is a material in 41 recipes, for example Dorgesh-kaan sphere, Goblin village sphere and Plain of Mud sphere. High Alchemy (55 Magic) turns one into 144 coins. Each cast uses a nature rune, 180 coins from a rune shop, and five fire runes that a fire staff replaces, so an alch loses about 36 coins; only alch it to clear space.
