Hello , Thank you very much for your interest. Since you are using a different battle system, it is logical that the plugin is not compatible since it is made to work based on the Battle Scene and as I understand, ABS is a system that runs on the map. Since I don't know how the Phoenix plugin works, and its complexity, I can't adapt it :(
You could contact the author of the plugin and perhaps they can make an adaptation for what you need. Greetings and i remain at your disposal!
