Fake Fortress

The Fake Fortress is a chestless nether fortress Ilsa finds in the nether.

I went to the NETHER :( (episode 3)
Ilsa finds a nether fortress, saying that if she finds just one chest, she'll feel like she did a good job. She sees blazes and the spawner that spawns them.

She enters the fortress, and starts fighting the blazes. As soon as she fought through them, she broke the spawner. She gets really happy with herself for doing that, and is surprised she isn't dead. She finds another spawner and breaks this one too. She gets even happier. She then accidentally throws her sword in lava found in the fortress. She gets sad and says that she got too cocky. She gets out a regular iron sword, and says that she can't use an iron sword because it's embarrassing. She searches the fortress many times, and hasn't found a chest. She gets angry and calls the fortress fake.

Later, she realizes that breaking the mob spawners was a mistake.

Trivia

 * Ilsa may have had bad luck, but she got a rare fortress. It is very rare for a fortress to spawn without a chest.
