At the beginning of
Deception IV: Blood Ties, you will learn that years ago, twelve saints sealed away the devil with twelve verses that were broken into pieces. 3000 years later, the devil is looking for those pieces so he has sent three beautiful daemons to the human realm with his "daughter" Laegrinna to find them. Laegrinna can’t actually fight at all. She doesn’t even carry a weapon. Instead, Caelea (Elaborate Trap Daemon), Veruza (Sadistic Trap Daemon), and Lilia (Humiliating Trap Daemon) lend her their powers to set up traps to combat the descendants of those saints and recover the pieces of the verses. Don’t feel too bad for these humans, though. They’ve fallen a long way from the saints their ancestors were.
The game is played in chapters. Before you start each chapter, you need to set up your traps and figure out what you are going to take into battle. You have a limited number of traps that you can take with you into each battle, so make sure to equip your favorite traps in the Change Diabolica screen before you start each battle. Make sure to select traps that work well together. It is definitely a balancing act to try and figure out what you can use well and which traps play nice with each other. You can also select your abilities under Change Diabolica. Since you only have two abilities to avoid the enemies with, choose wisely.
Each trap is of a different type and has a different class to it. You can tell the class by the color. Red is Sadistic, Blue is Elaborate, and Yellow is Humiliating. There are lots of different types. Enemies may be weak or strong against various types, so make sure to keep that in mind. Traps can be set on three different terrains: Walls, Floor, and Ceiling. Some traps immobilize enemies, while others cause them to move a specific way. You need to have traps that will all work together and send the enemies where you want them to go. The good thing is that at any time, you can pause the game and reset your traps. You can only have a few set at once, but you can move them around whenever they aren’t in the middle of trapping. This can make things a bit tedious when you’re having trouble getting things to spring like you want, but once you get it right, there is something extremely satisfying about making someone step on a rake, which makes them stumble into a bear trap, which then causes them to be stuck where a boulder will roll over them, just as one example.
