how to make a units who appear anywhere in the map to be on ground not on clif

 

[Lord Nightbringer]

Have the trigger choose a random point, then have an If/Then/Else (multiple) function. For the condition, use Boolean - Environment Pathing is Off, set the first field to the random point the trigger chose, and have the other side of the Boolean equal to False. Under the Then actions, have it create the creature as normal, and under the Else actions, tell it to repeat the trigger.
