In the database the scope is set to user, everything else is blank. In the plugin the summon animation is set to 96 and the called actor is 5. This is all done in the demo project.
Viewing post in Summon Skill not working.
Ok first, don't set summon scope to user, if skill scope is user, it will only summon on self.
Second, please see latest update: v1.5.5 - Removed Summon Limitation - RPG Maker MV/MZ: Tactical Battle System by Synrec (itch.io)
