Cursed Panda

Appears as just a regular Panda. Has more HP, likely deals more damage, and will semi-spam curse at you. If you have some MR, and 2500+ DR, this is a pretty free fight.

Drops the Panda Skull, which can take in an AG gem. Popular choice to start building up MR, especially for MA's. Note that the Ryujin gem alters the rarity of the helmet, so don't stress about farming this, just get one and move on.

Cursed Panda can be found in a currently unmapped area by heading North from the AG Portal Room and sticking to the north wall, taking the stairs when you come to them. Then, heading north (circling around the northing building that will be in your way) and taking the rope up. Follow this area until you get to a Pagoda-like building where you can either go west or north with a weird floor visual. West takes you deeper into Pagoda (and Cursed Panda), and North takes you to a giant room filled with water and Ryujin.

Cursed Panda can patrol a ways around his area, and there is another one even deeper into the dungeoun.
