This is driving me round the bend! I made part 4 up, it fitted all the guidelines, I threw it in the cauldron... and it didn't work!

So I'm trying it through again and I dunno what I'll do if it doesn't work this time either

Edit: It worked!!! Hurrrah! But I got Platinum Mist as an ingredient next, and it hasn't been discovered yet so I can't get any further yet

*twiddles thumbs*

I've been using Laoran_Flare 's guide mostly and if you go look at this petpage it has all the formulae you could ever need to help you get it spot on!

There is also this petpage which lists what to do for every step and is very thorough!

Hope this helps
