Ironman verdict

Smouldering stone 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 2 monsters for it.

The lowest-level monster that drops it is Hellhound (level 136), at 1/16,384, about one in 16,384 kills. The best rate is from Cerberus (level 318): 1/520. The 2 monsters we list with a combat level range from level 136 to 318.

Among the bosses we cover, Cerberus drops it, and it is one of the drops we flag as worth chasing there.

It is a material in 3 recipes: Infernal axe (61 Woodcutting, 85 Firemaking), Infernal harpoon (75 Fishing, 85 Cooking) and Infernal pickaxe (61 Mining, 85 Smithing). High Alchemy (55 Magic) turns one into 27,000 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 26,820 coins.

Where to get it, easiest first

1.KillHellhound · level 136, drops one at 1/16,384 (about one in 16,384 kills)
2.KillCerberus · level 318, drops one at 1/520 (about one in 520 kills)

Our order: buying first, then making it (lowest skill level first), then killing for it (lowest-level monster first), then other sources. Up to three of each; the full lists are below.
