Fusewood is one of the nether trees added by Natura. It can be characterized by a dark green to olive color, and it tends to explode after punching out a log. Fusewood tools must be created with fusewood sticks and planks like other Nether tree tools.
Fusewood, like much other Nether wood, has a tool rating (durability+efficiency) between wood and stone.
Due to its rarity and tendency to explode when being collected, Fusewood is a very difficult wood to obtain. It has the third highest durability of the four Nether woods (Ghostwood, Darkwood, Bloodwood, Fusewood), so searching for an elusive Bloodwood (highest durability) may be a better alternative.
When breaking the log in creative, it will still explode.
