Sometimes happens to use poly without to use earrings or skill pedant because we are humans and we forget. Sometimes we die 1 min after we used it because of lag or bad connection. It's just a waste of poly marbles.
I suggest to make a timing ( 20-30mins ) for poly and you can use it 3 times in this time. Even if you die you can use it again.
The item should look like this.
Savage Minion Poly Marble
Time remaining: 30 mins. ( 29 mins 17 seconds... )
Used: 1 time.
