This is pretty simple to fix, but I'll need some space to explain it all.
Okay...
:Make a location over the entire area and we'll call that Critters:
:Make another location over each row of archons like this:
__
|O|
|XO|
|XOX|
|XOXO|etc.
:Now, have it go like this:
Conditions:Whatever:
Actions:
Kill all Critters at Critters
wait ???(whatever)
Kill all Archon at Archons 1
wait ???
Kill all Archon at Archons 2
wait ???:
Etc. etc.
