I would like craft amus. I have many resources (for ~20 amus) , 70% of chance to craft. And i tried and tried, but 9 times failed in a row ?! what pony puppies is that!? How its possible?!

Lately everyone started using a word 'pony'...

You should be happy it's 70%! I'd say that an amulet is more valuable than potions, and potions have 40% chance of creation...
I hope there'll be news about the next patch soon enough, I guess all of us would be grateful for some info.
