Got it at last for people that do not know:
After melding ~10+ materia speak to the goblin and select: Secret materia techniques and if you have melded enough he will swap your melder for augmented....
Got it and 1st thing i did was put 2 T3 STR in cobalt red gauntlets resulting in +27 lol
Also the % differs on the value of the Tier materia also I.E. you will get diff % for a T3 +15 STR and T3 +11 STR...
