He really is pretty tough and with his Dinoman in the corner and three Ghouls in front he has decent backup. Fortunately you’ve fought all sorts of Weres like this so you should be okay although Yaksa is a tougher one.
You finally meet Asura and he offers you a trip to heaven.

Chapter 4 – Asura
Heaven’s Door
You see some scenes with Asura and Deva and their plans for Heaven.
As your party recovers and moves on, Nagini stops them. She then turns into a dragon similar to Ryorin and a battle ensues.
Left of where your three groups of two start off, and you’ll see a pole of some sort that you can destroy for a Cap of Wisdom. Now if you go to the northeast part of the screen (the side that isn’t destroyed) you can use a WereAttack on another pole for a Magic+ Potion.
Nagini has FlameBreath and ThunderClap. ThunderClap hits a lot of your allies and FlameBreath hits a more narrow yet far reaching crowd. So she’s going to be your typcial Were using high level magic on your entire party. Her subordinates aren’t that tricky as Harpy’s are basically Operator’s and the Dinomen are easily reachable and defeatable.
Have you ever wondered about Sanzo?
Great guide
