Your Altar Kit appears to be well balanced. There appears to be a guide that comes with it so I would start there as there might be something of interest to you.
With the Pendulum you have to first establish communication with it first before using. I attach a link. I have just found an interesting website.

I would cleanse any tool or object before using.
Enjoy your spell work
