Theres and neutral Elite Frog after the Bat boss and it has a 5% chance of dropping [Glowing Magical Bracelets] and many other BOE blues. Heres a pic I made to help you get there. The Purple area is the bat boss you need to kil to open up the right side of the cave to the npc that drops its, sorry if its hard to read just tried to make a quick map with a route to it. To get out of the dungeon just follow the way back. I got a Enduring Cap and Glowing magical bracelets x2 in under a hour doing this method.
