I've been trying for more than a few hours to fight Anacondaur and Grendels to get some Dragon Skins to upgrade weapons. I've fought probably 30-40 total battles, with about half as Anacondaur. It's bad enough that I've accidentally leveled to a party average of ~36, and I've still never gotten a Dragon Skin drop.
According to the guides, Anacondaur should drop Dragon Skins nearly every battle, especially with my current level.
What gives? I just want to upgrade some items.
