Step 1: What You Need:
Find a place to build and make a platform.
Make a two wide and three high room with a one block hole for the darts to go through. Then make it in a enclosed space like shown in the picture. Then put a lever on top
Put down the slime statue and the dart trap like shown then put the one sec timer on the dart trap and the three sec timer above the statue.
Wire the slime statue to the 3 sec timer and the dart trap to the 1 sec timer then connect both wires to the lever.
