Hello there... I wanted to make a trigger that for the first 10 minutes of the game, every 30 seconds, it spawns 10 Jahrakal (Level 2) creeps on the center of the map. And the next 10 minutes, the creeps spawn will be Broodmother (Level 3). Next 10 minutes, Jahrakal Berserker (Level 5) and so on. I can make a trigger for every x minutes spawn y units, but what can I do with this condition? Anyone has suggestions?
