it's like this:
// Armors
0,70,0,0,100:0,100:0,100:0,100:0,60:0,40:0,40:0,20:0,20:0,10:0
you see 60:0 this is for +5 it tells you 60% success rate for +5. so if you want to increase it just change like 80 = 80% // Level 1 weapons 1,200,8,300,100:0,100:0,100:0,100:0,100:0,100:0,100:0,60:0,40:0,20:0
the same goes for level 1 weapon the 60 is for +8 = 60% success rate.
