Heavenly Cross and Evasion Prism don't work as described.
Having them 'Deal Magic Damage' is causing them to be only castable on enemies...meaning they're buffing the mobs instead of the party.
Had it happen twice on groups of Pygmy Wolves. Instead of evasion for me, the wolves dodged every attack I made after casting Evasion, and it actually healed their group instead of mine.
Currently both Heavenly Cross and Evasion Triangle are useless because of this.
