Since no one will prolly see it in that other thread here it is again, so no one breaks elites anymore xD
Chance to Succeed
[103-(current % on item + enchant mat%)]+(1 for each 100 luck)
So if u had a 60% item using a SoE with 500 luck it would be like this...
[103-(60%+12%)]+(5) = 36% chance to Succeed.
Chance to Break
[(current % + enchant mat%)] -57- (1 for each 100 luck)
So same situation, 60% item with Soe and 500 luck would be...
[(60%+12%)]-57-(5)= 10% chance to break.
The Safe point in this game with 0 luck is 57% and increases by 1% for each 100 luck as i shall demonstrate in the next few equations.
Example 1.
48% item enchant with BS and 0 luck ur break safe % is 57%.
[(48%+9%)]-57-(0)= 0% chance to break.
Example 2.
Now lets say u have 300 luck ur break safe % is now 60% as shown below.
48% item with Soe and 300 luck
[(48%+12%)]-57-(3)= 0% chance to break.
Be warned, u always have 1% chance to break no mater what % your item is. So be safe! and always wear protection. 
thnx,
