Yes, it's possible. We can define a variable to store the CD. I'll allow configuration in both turns and frames. I have this code ready in another plugin; I'll just adapt it. I'll release the version with this verification shortly.
It's ready. I've added the v6 file which has a countdown system based on frames (active frames) or turns. I've also added a unique summoning function per battle. Again, it was superficially tested. In the next free session, I'll test all the new features of this plugin and release a version.
