Oh dear, the grinding. The part between Moonflow - North Bank and this battle takes half of forever, thanks to those damn Poison Fangs and Silver Hourglasses. I got eleven and two respectively before I couldn't take it any more; I really should've gotten nineteen and three respectively, but there's only so much a man can take. As you can see, I ended up with boatloads of other items in the process.

The first customization in the challenge is invisible in this battle; I got Yuna a Reticent Staff (Silencestrike), which comes in handy both in the Macalania Woods (to silence Blue Elements) and lateron in the Via Purifico (to silence Maze Larvae). As for Spherimorph - I could've sped things up by using harder-hitting items, but I figured I'd save those for Wendigo and Evrae instead. Admittedly, I underestimated the overkill of items I had here.
