so I've looked around here and on the different wikis but i never see anywhere explain how i equip my pets ,even in the older versions i were never able to and still i can't place a pet in its slot and i would love to find out how
You need to capture an animal. Then put the capture pod in the pet slot. Also support section is only for reporting bugs.
Not all pets can be put into the pet slot. I think only Small quadruped monsters and a few uniques. The rest you put in the pet tether.
