This was a script made for me by A-Moonless-Night
It was before I knew how to do it myself.
So I never made it but I use it in my project so here it is for others.
Requires V's Promotion system v1.2 - paid for script for commercial projects
What it does:
Makes the promotion require an item.
The intent was to have it work like the promotion from Final Fantasy 1
Use the rat tail to promote the character
Credit and Thanks
