Sinister Wood

Sinister Wood, alternatively known as Glow Wood, is a wood type that was added in the 2015 October Halloween Update along with Spook Wood. The tree grows exclusively in the month of October and has an extremely low spawn rate but can be found anywhere on the map, including the mountains and the ocean floor.

This tree can be found anywhere on the map, as shown in the gallery, but also as a result of the numerous duplication methods which have existed throughout the history of the game. This wood type can still be purchased from other players, even though it has been circulating throughout the market for more than a year.

The external properties of this tree are identical to Spook Wood (really black, and roughly the same size), with the only exception being that this tree seems to grow many twigs and limbs, making most planks small.

The interior properties are currently the most demanded, as it is a bright orange-yellow, giving off a gold glow, which is similar to Cavecrawler Wood. Both Sinister and Cavecrawler Wood emit a glow due to their Neon material.

This wood is tied with Spook Wood for being the thickest and heaviest tree in the game, taking over 150 chops with a Rukiryaxe to take down.

It is to be noted that the bark of this tree is also made from Neon material (unlike Spook Wood).
