Ironman verdict
Obsidian cape (r) 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 other source for it.
It does not drop from monsters and no shop stocks it. It comes from master clue scrolls. It is on the master clue scroll reward table, so every master clue you complete is a chance at it.
It is worn in the cape slot; its biggest bonuses are +9 stab defence and +9 slash defence.
No recipe in our data uses it as a material. High Alchemy (55 Magic) turns one into 36,000 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 35,820 coins.
