Mourning Wood

Mourning Wood is a hardmode miniboss encountered during the mid-to-final waves of the Pumpkin Moon.

During combat, the Mourning Wood alternates between firing a volley of flaming spikes straight at the player that pass through blocks, and firing a jet of spark-like flames  that are affected by gravity and stay on the ground for a while, doing damage to players that touch them. This can be frustrating while fending off other enemies, but using a flight accessory helps immensely, as the flames aren't too accurate to the player's location.

Tips

 * Floats through blocks to reach the target player, resembling Wraith's behavior, but otherwise walks on surfaces and cannot jump.
 * Due to this it's perfectly capable of fitting into spaces much less than its size.
 * Not damaged by lava.
 * Immune to Cursed Flames, Confusion and Frostburn debuffs.
 * With each additional wave, the chance that the Mourning Wood will drop an item when killed increases. A Mourning Wood killed during wave 15 is guaranteed to drop a random item, as well as a trophy.

Trivia

 * The name "Mourning Wood" appears to be a play on the term "Morning Wood"
