Hi, im making a rpg map and i was wondering if it is possible to make units in a region have a chance to drop specific items.

event:
unit dies
condition:
unit type of dying unit equal to your unit
unit is in region(your region)
event:
Set X to Random number between 1 and 10
(.IF THEN ELSE stuff,)

If X = less or equal 3
THEN create Item1 at unit position
ELSE
IF X = greater than 3 AND less or equal 7
THEN create Item2 at unit position
ELSE
...

and so on
