Why did this fail to achieve HQ?

[Shadygrove]

I have even failed to gather a item when said 100% rate. I have even failed to hq a item at 99%. I once went though over 100 materia when said 35% chance to socket. The rng sucks on this game.

Recently while overmelding I had back to back first trys at 10 & 7%. I still blew up a lot of meteria that day.

Means nothing.
