Omg you're such a retard it's not even funny... There is no "trick" to the anvil, it's a set percentage!
Grats on the +5 spear, now don't break it to +6. :P[/b]
You're succes pourcentage is based on a LOT of factors
I'll not say my tricks CAUZ one of it is LEGAL but you are SURE to up something to +6 to +7 (at like 99% whithout a trina!)
But its a really tough trick that take you a lot of money and time
