If you use two Morion blades, you can only attack with a morion blade, nothing else. Since you would be using both, you cant cast magic or miracles without the catalysts or talismans to support it.
576 Attack power is not very amazing IMHO.I have gone over 1200 attack power with a Dragon Bone Smasher +5 on my all-around MAGE character.
Morion blade is not a good weapon to use to attack people with in the first place: too slow and the range is horrible.
