Completely upgrade all weapons and magic

For this trophy, you must completely upgrade all your weapons and magic. To do this you'll need to collect enough red orbs during your playthrough. You can do this by collecting the red orbs from defeated enemies, destroying various objects, or by opening chests found throughout the game. Unfortunately you're not going to have everything upgraded by the time you're done with your first playthrough. Thankfully, you can earn red orbs in the Combat Arena found in the Treasures options.
