How does Locust Swarm works? I'm kinda not sure about it. What does the damage return threshold mean? And also is the healing periodic? Can I modify it? I gave my swarm 4000 damage and 0.5 sec att spd, but it dosent attack every 0.5, and it heal the user 1k hp even though its does 4000 and its threshold is 1k + the heal % is 25?
