Unfortunately, you can't configure systems within Object Editor data fields which I believe you're pointing to because of that endurance aura you've been explaining about. All spells/systems published here are configurable within Trigger Editor; configurable data like area, filters, radius, ranges, and effects should be scripted for a flexible configuration (except for the data which we couldn't absolutely manipulate before such as cooldown, manacost, description) Uncle already showed an example. However, a knockback system should have an instance check for the unit to filter out for enumeration. Based on that repulsive magnetic force GIF you provided, it doesn't exactly match the behavior of that Repel linked by Hermit. But I think that's enough to solve your problem. You just confused Icemanbo in that 'without GUI' part because there's no such thing. He's just trying to understand but it turns out that you should be the one to understand what you're trying to point out honestly.
