The "Karate book" is well, a book. It takes your secondary slot but comes with rewards. Punching energy is reduced to 6 and Kicking energy is reduced to 8. Punching now does 20 damage and kicking does 45 damage. Punching has a effect of giving a 50% chance Concussion if tripped (3 seconds of effect) and Kicking reduces the speed of any mob (player or zombie) by 4 (of effect 6 seconds). You must be ranked 15 and the cost of the "book" is 25,000. The animations can be a reuse of PlaceRebuilder's other game, Martial Heroes.
