Neopets battledome ghost lupe?

If you want to defeat him you should raise your HP and Attack. And you just have to keep trying. If you drew once, Im sure you can defeat him. Try different weapons, and which ever seems to work best, use that. I havnt ever faced him, so Im not sure what would be best. But if he can beat you in one hit, you need to raise your HP. Good luck! :D
