May want to shift your efforts towards the Advanced AARPG Combat System. Unfortunately reading a lot of nasty things about GregS losing control of his Discord and grifters taking it over, and little to no support recently. (And URPG Mastery has tutorials and documentation nearly as extensive as yours. GregS not so much.)
Video tutorials on anything would be much appreciated. As for AI, maybe a basic hierarchical structure regarding distance from the player, close enough Grapple Attempt, or if striking would be used instead.
