Ironman verdict

Obsidian platelegs is a members item. Other players trade it, but an Ironman cannot use the Grand Exchange or trade, so you get your own. We list 1 monster and 1 shop for it.

The lowest-level monster that drops it is TzHaar-Ket (level 221), at 1/2,000, about one in 2,000 kills. It is also on offer at TzHaar-Hur-Zal's Equipment Store for 100500 tokkul, not coins.

It is worn in the legs slot; its biggest bonuses are +46 stab defence and +43 slash defence. The shop that stocks it is in Mor Ul Rek.

No recipe in our data uses it as a material. High Alchemy (55 Magic) turns one into 40,200 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 nets about 40,020 coins.
