im sooo stuck im on chapter three and im trying to stop this crazy bitch from opening the portal in cedar villae or something like that does anyone one know how to hit her >.<

Yeah, I hated this part too, just switch to Illius and keep hitting her with fully charged ranged attacks, and if any one of the enemies gets near you, hope you have a super charged.

Like said above,use Illius hes the best for this boss and the spider thing. Although i think ur forced to use him alot taking away from the other characters. I prefer using the rouge lady myself b/c shes fast and hits good.
