I bet you think converting level 90 gear gives level IV materia 100% of the time.

Nope.
I guess there's even less of a reason to spirit bond level 70 gear now? Not like those pieces of gear are cheap enough to spirit bond anyways.
Thanks SE. Now instead of spending another few weeks getting my novus, I can instead spend that time trying to find another way to make gil and buy materia that will inevitably be inflated to several times their current price because no one can spirit bond in dungeons.
Also, in case anyone was wondering why I converted that robe, it was just something I used a long time ago. Now that I have a daystar robe, and I can't sell it because it was bound to me, it was just sitting in my retainer.
