How do I make enemies die at not the same time?

So it's not exactly about enemies dying at the same time that is the problem, it's more of a bug/glitch that's happening.

So basically, enemies have like a one in five chance of dropping a "Gem", in my game I have an AOE (Area of effect) weapon, and if it kills one enemy that were supposed to drop a gem, all of the enemies killed at the same time will drop gems.

How can I prevent this? I was thinking maybe destroying enemies at not the same time would help (hence the title), but I'm up for other suggestions!

Without seeing the events can only guess you are missing a 'for each enemy' in the condition.

Yes that is right. I do not have a "for each enemy" in any of my events

Alright so I tried it out and it worked. Thank you!
