As somebody else posted, if you can clear the first 3 nodes you shouldn't have any problem getting them. (they're at the 140kish level)

If you can't, probably not.

My 2 cents, should have had 1 copy at 90,000 (clearing 2 nodes per day + some pumpkins) 2nd copy at 140k, (3 nodes per day) and 3rd at 225k. (all nodes per day, I assume?)

So just about everybody gets the basic 5*, more dedicated players would be able to get enhanced versions.

(or possibly, a 4* with same look at 90k)
