@Gibiana Perhaps because you haven’t given it a task. Try something small but attainable to give it something to do. Also try focusing more energy into the servitor to give it spark and use the task as the intention.
Also once the ritual is completed do not doubt yourself or your powers. Do not focus on the servitor project again. Jump into another project immediately. This stops you from lusting for the result and gives the servitor time to do what it needs to.
Also please write an introduction in the appropriate thread for introduction. Introduction Thread So fellow members can learn about a bit about yourself and what your looking to achieve on the forum.
