Infernal axe

The infernal axe is a special type of axe that is created by using a smouldering stone on a dragon axe, requiring an unboosted level of 61 Woodcutting and 85 Firemaking. Creating the axe grants 350 Firemaking and 200 Woodcutting experience.

While chopping a tree with the infernal axe in the inventory or equipped, there is a 1/3 chance that the logs will be burnt as they are chopped, giving half of the Firemaking experience that would usually be gained by burning them the normal way. For example, redwood logs that are burnt by the infernal axe (which does not require level 90 Firemaking) will grant 175 Firemaking experience rather than the 350 experience that is granted by burning it normally.

The infernal axe will be able to burn 5,000 logs before degrading, requiring another smouldering stone or dragon axe to recharge it. When fully depleted, you can still use it as a regular dragon axe.

The infernal axe possesses the same special attack as the dragon axe, in which it boosts a players Woodcutting level by 3 and requires 100% special to use.

When fighting the Wintertodt, the infernal axe does not consume bruma roots, acting instead as a regular axe. The same can be said for chopping Sulliuscep mushrooms.
