Sinister Wood

, also known as Sinister Wood, is a wood type that was added in the 2015 October Halloween Update along with Spook Wood. The tree grew exclusively for the month of October for 2015 and had an extremely low spawn rate but could be found in any biome.

A result of the numerous duplication methods which have existed throughout the history of the game is that this wood type can still be purchased from other players.

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 highly demanded, as it is a bright orange-yellow, giving off a gold glow, similar to Cavecrawler Wood. Both Glow Wood and Cavecrawler Wood emit a glow due to them being made from 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.

The tree, and wood, is confirmed to be missing from game data. It's believed to have been removed from the game.

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