Recently on Civcraft, it was reported that a group of players had been killing people with books. To be more specific, the book and quills were being used to kill players in protection 4 diamond armor in 1 or 2 hits; the victims were also set on fire. Needless to say, the players with books of Sharpness 32767 were immediately banned for obvious cheating.

Very quickly, we discovered that the cheaters had simply input a pattern of text into books and upon signing them, the books had absurd enchantments. Example A. After analysing the player data of the banned players, I noticed that each signed book and quill (ID: 387) had a value of 32767, which is just a little absurd.

I am still looking into how the exploit works, such as what one must type into the book and quill to get the ridiculous enchantment.

In the meantime, book and quills are disabled on Civcraft (when a player attempts to use one, the books are imediately deleted from the inventory.)

Note: I only have positive confirmation of the exploit working in 1.3.2. I have no idea if it was fixed in 1.4.
