Wraiths are 困难模式 ghost-like 敌怪 that can travel through 物块s. They can inflict the 缓慢 减益 on the player. They have black bodies, which render them almost completely invisible in dark areas, but have two glowing red eyes that are visible from within the darkness. They spawn at the 地表 layer at 夜晚.
Wraiths appear to be flying, however within empty space they can only hover slightly off the ground. They can only fly upwards when they have foreground blocks to "swim" through.
Wraiths are immune to the 中毒, 着火了！, 诅咒地狱, 毒液, 困惑, and 暗影焰 debuffs.
- One or two Wraiths spawn upon destroying a Demon or Crimson 祭坛, regardless of the time of day.
- Wraiths are more common during a 新月.
- Wraiths can be attacked through walls with 近战武器s or other weapons whose attack animation does not end when it hits a wall - this makes 矛 especially effective.
- Wraiths will not trigger 压力板s, and will just go through them instead. This makes them incapable of activating any sort of 机关.
- Any structure raised least 8 tiles above the surface will prevent a Wraith from levitating up and through it.
