The Forgotten Axe is an unlockable axe that can be found inside of the Lost Cave. The axe has horrific damage for almost all cases. However, it does the most damage upon leafless trees. This means that Gold Wood and soon-to-die trees are the best for this axe.
The Forgotten Axe is a black and white sketch filter of the Silver Axe. -
The axe can be obtained by dying in the Lost Cave near the Skeleton while a Hardened Axe is equipped. Upon death, the Hardened Axe will convert into the Forgotten Axe and the player will have to go back to the cave to retrieve it.
