  • When there are no pages, use physical attacks against Grimoire Rubrum to deal damage to him. At this time you will not do any harm to him if you cast magic.
  • There will come a point where the critical hit circle will appear , attack until you see a sequence.
  • Now you will see that it surrounds itself with a magical shield . You won't be able to do any damage to him, so just attack until you see another sequence.
  • In this third phase you will be able to destroy his magic shield: cast your own magic to break it sooner .
  • Once you have taken down the shield, you can use physical attacks to damage Grimoire Rubrum. Remember that the book itself is immune to magic , don't bother to keep casting spells when the shield has fallen.
