Astral logs

Astral logs are cut from an Astral tree, requiring 60 Woodcutting and giving 200 Woodcutting XP when cut with a regular hatchet, 400 Woodcutting XP when cut with a Sacred clay hatchet or with Skoll boot equipped, and 425 when cut with a Volatile clay hatchet.

They can be lit with the Firemaking skill, needing 60 Firemaking, offering 230 Firemaking XP when lit, or a maximum 252.5 when added to a bonfire. Astral logs can only be accessed after successfully completing the quest Across The Sky, in which they are used in making special glass orbs.

Astral logs are considered a viable alternative to Yew logs when it comes to training Woodcutting and Firemaking, as they offer better experience at the same level. However, they require a somewhat long quest to be completed before they can be grown, and regrow at a very slow rate after being felled the first time. The only other upside is that, as a player-grown tree, one does not have to worry about competing with others for resources.
