OK so I'm lvl 23 and soloed mariner reef. I didn't lock the map or solo party. After killing boss krunch appears so I preceded to alert my guild and invite a few to help kill. Well no one could join. I tried different people. My phone battery ended up dieing so I lost out. Just would like to know how to get people in the map after he spawns so I don't miss out again. I know you can as I've had people invite me on other characters of mine.
