Mummies

Mummies are Hardmode Desert enemies. They spawn in areas where Sand Blocks are present, and follow the Fighter AI (behaving similar to Zombies).

There are several different versions of Mummies: Dark Mummies, Blood Mummies and Light Mummies, who spawn in Corrupted Deserts (and in Crimson Deserts), Crimson Deserts and Hallowed Deserts, respectively, and Shadow Mummies and Spectral Mummies, who are exclusive to the  of Terraria.

Dark Mummies are 150% faster than other Mummies. All mummies receive a 200% speed increase when they are reduced to 50% health or lower. In addition, mummies inflict the following debuffs:
 * Regular Mummies: Slow
 * Dark Mummies/Blood Mummies/Shadow Mummies: Silenced, Darkness
 * Light Mummies/Spectral Mummies: Confused

Tips

 * Dark, Blood and Light Mummies can easily be farmed for their shards by Corrupting or Hallowing a section of Desert, or making an artificial Desert. All that is necessary is a one-wide flat surface of Pearlsand, Ebonsand, or Crimsand. However, do not have both surfaces too close to each other, as one cancels out the other.

Trivia

 * The head of the -exclusive Shadow Mummy looks like a Skeleton's Skull.
 * The mummies in Terraria are bound incorrectly: In, the feet of the mummies were bound together and their hands were bound on their sides. However, in Terraria (and almost every other fictional work), the hands and feet of the mummies are bound so that they could move freely.
