Tenchu: Dark Secret Cheats (Nintendo DS)

An easy way to get scrolls is to fill your inventory with bamboo traps. Then, simply line
them up one after another in the path of an enemy so that he will hit the first one and
bounce to the next one until he has hit all eight traps. If done correctly, each time the
enemy bounces off a trap he will drop one of the following: money, ninja gear ingredients,
or sometimes a scroll. Also, you can sell the eight trap kills you just got at the shop
for money.

The ten types of kills you can get are as follows: Sword Kill, Trap Kill, Poison Kill,
Water Kill, Explosive Kill, Spike Kill, Tiger-Trap Kill, Fall Kill, Surprise Kill, and
Joke Kill. Note: In order to get Surprise Kills and Joke Kills, you need to unlock
the scrolls that allow you to make Joke Books and Surprise Boxes. Once you get kills with
all the different types, the background of that enemy's kill gallery will turn gold.
