Poor guy...Well, despite being a reanimated corpse, Wugui is Wugui. Same absorbing skills. Same "Game of Death". It might take a little longer than before, but keep clobbering and eventually, this poor soul will have his rest... Like Yamaraja War, the Cursed Puppet will use Nightmare so Heaven's Fiend will be mostly recommend to keep your HP high. Other than that keep nailing him with physical attacks and he will go down.
