I made a zealot pet for myself. I figured I should share it. I tried to make it the zealot the same size as a person. I've included the two packages. NOTE: THIS IS MEANT TO REPLACE THE IMAGINARY PET SO IMAGINARY PET MOD HAS TO BE ENABLED FIRST
normal zealot is a little weaker and only has zealot bolt spell
overpowered is what I used with my destroyer with medea's spells and all zealot spells except for summon.
There's two skins available I started with the zealot champion skin but then realized i liked the normal zealot skin a bit better. So I've included both. The screenshots should show the differences.
Default Skin__________________________Champion Skin

There is a permanent zealot fish that would transform you called zealot fish but i didn't put it in a store. I haven't fished enough but theoretically you could get it.
Otherwise, you could give yourself the fish by adding it to a store yourself read the readme for instructions
[EDIT] I just realized I gave the base models the original zealot GUID so my base was showing up where the original zealot should have. That has been corrected now.
Also I made the normal versions a little weaker for balance [EDIT]
