The dragon axe + smouldering stone is effectively the cost of the dragon axe plus the stone, since the stone upgrades it into an infernal axe. Recent public price snippets show the dragon axe around 79k–89k and the smouldering stone around 1.1M–2.3M , so the combo is roughly 1.18M to 2.39M gp depending on the source and timing.

Quick breakdown

  • Dragon axe: about 79k–89k.
  • Smouldering stone: about 1.1M–2.3M.
  • Total: about 1.18M–2.39M gp.

Note on price swings

These items move a lot, especially the stone, so the exact total can change quickly. If you’re pricing it for a buy/sell today, the stone is the part that really drives the cost.

Practical answer

If you just want a rough answer for OSRS trading right now, assume around 1.2M+ gp minimum for the combo, and potentially much more if the smouldering stone is near the higher quoted range.
