Needed program- Entity
Update was getting rid of Insolence and just swapping in Entity. This part of the update was found by PyroBlizzard.
Make sure you start off with a clean map.
In this tut I will add a few more Wraiths to the map, but you can add whatever you want.
Ok start off by opening Entity. Then go the itmc tag and choose a weapon, doesn't matter which one.
Then Right Click it and select Duplicate.

Now you will see the text 'Item' in the left side. Click it so its highlighted in blue.

Then right click it and click Swap. After that a little box will come up.
Change all that around until you find what you want, mine will be the wraith. After you find what you want click Swap idents.

Then click the Save button no the right side. Now open the scnr tag, red in the pic, and go to the Netgame Equipment, red in picture
and Right Click it and click Clone Chunks. Then a little box will pop up called the Chunk Cloner. Clone as many items as you want, so 5
chunks will make the map have 5 more Wraiths, or whatever you pick.

After you find your specified number click Add Chunks To Tag. After 15-30 seconds a box will pop up saying Done. Then save the changes.
Ok now while still in the scnr tag right click and Click Display then Idents.

Now you will see a lot of scens, ligh, and other tags. All you need to worry about are the itmc
