So I went against my original plan and decided to soldier on to finish Yunica's story before continuing with the awesome character. I think my game was glitched, because the moment I got the last armor I went from taking 35-40 dmg from regular mobs to taking 5-8, so there was definitely something odd going on. Either way, once Yunica stopped being the weakest glass cannon in history it became too easy to go all the way to the last boss.
Again, the localization completely destroyed Yunica's appeal, and her story is pretty depressing so... yeah moving on. XD
Next stop, clawing my way to the top again. Literally.
