-*getmobdrops(<mob id>)
+*getmobdrops(<mob_id>, <item_id_array>{, <drop_rate_array>});
 
-This command will find all drops of the specified mob and return the item
-IDs and drop percentages into arrays of temporary global variables.
-getmobdrops() returns true if successful and false if the mob ID doesn't
-exist.
-
-Upon executing this,
-
-$@MobDrop_item[] is a global temporary number array which contains the
-                 item IDs of the monster's drops.
-
-$@MobDrop_rate[] is a global temporary number array which contains the
-                 drop percentages of each item. (1 = .01%)
-
-$@MobDrop_count  is the number of item drops found.
-
-Be sure to use $@MobDrop_count to go through the arrays, and not
-'getarraysize', because the temporary global arrays are not cleared
-between runs of 'getmobdrops'. If a mob with 7 item drops is looked up,
-the arrays would have 7 elements. But if another mob is looked up and it
-only has 5 item drops, the server will not clear the arrays for you,
-overwriting the values instead. So in addition to returning the 5 item
-drops, the 6th and 7th elements from the last call remain, and you will
-get 5+2 item drops, of which the last 2 don't belong to the new mob.
-$@MobDrop_count will always contain the correct number (5), unlike
-getarraysize() which would return 7 in this case.
+This command will find drops information of the specified <mob_id>, copy the
+item ids on to <item_id_array> and drop rate on to <drop_rate_array> if provided.
+Returns the number of items found. Will return 0 if <mob_id> is invalid.
 
 Example:
-
 	// get a Mob ID from the user
 	input(.@mob_id);
 
-	if (getmobdrops(.@mob_id)) { // getmobdrops() returns true on success
-		// immediately copy global temporary variables into scope
-		// variables, since we don't know when getmobdrops() will get
-		// called again for another mob, overwriting your global temporary
-		// variables.
-		.@count = $@MobDrop_count;
-		copyarray(.@item[0], $@MobDrop_item[0], .@count);
-		copyarray(.@rate[0], $@MobDrop_rate[0], .@count);
-
+	.@count = getmobdrops(.@mob_id, .@item, .@rate);
+
+	if (.@count) {
 		mes(getmonsterinfo(.@mob_id, MOB_NAME) + " - " + .@count + " drops found:");
 		for (.@i = 0; .@i < .@count; ++.@i) {
 			mes(.@item[.@i] + " (" + getitemname(.@item[.@i]) + ") " + .@rate[.@i]/100 + ((.@rate[.@i]%100 < 10) ? ".0":".") + .@rate[.@i]%100 + "%");
