What is the probability of getting the Unicorn Horn and Amulet in Castle Keep?

I've gone through the Castle Keep like 5 times and still have no Unicorn Horn or Amulet.

How can I go about getting the Unicorn Horn and Amulet? What is the probability of getting the Unicorn Horn and Amulet in Castle Keep?

• It's completely random. You get the horn from a unicorn, and the amulet from a...wall troll? I think? Commented May 11, 2013 at 22:20
• Thanks for the answer. But is there a reason why this question has a negative 1 on it? I mean, cmon. It's a completely legit question...

• As @fbueckert said, it's completely random.

• @Cat I edited in "What is the probability of getting the Unicorn Horn and Amulet" into your question and changed the title, so the question can be more answerable (get a better explanation than "it's completely random"). If you do not like this, just roll back a previous edit or edit the question again. Commented May 12, 2013 at 2:04

The magical horn and old amulet are guaranteed drops from the wall zombie and the unicorn lacking a kidney (`WZW`, `UNI`). Things is, you don't get these enemies each run.
