I got my diamond in september (i think) by using mindvolt and forestfire, it was an accident i just thought they would look cool on the island with ther wierd heads.
Anyway to day mu dougher asked me what combo i used and i told her, she tries and got 44 h directly. So she akes if she can try on my phone account and i said yes. She does that and got it first try again, for me this time. Happy as she is she calls her father at work and askes if she can try on his ipad, he says yes and she screems from her room - I DON'T BELIVE IT I GOT IT AGAIN! So three diamonds out of three tries with that combo for her to day!
Just wanted to share if it helps someone else get it
good luck
