| Hello Empaths,|
The Guardian Spirit has undergone a change similar to that of the Necromancer Zombie -- the calculation used to determine its level (based on your TM skill) has changed. Potency also now has a larger effect on the warrior's level, so you should have more incentive to cast as close to the cap as you can. There is a bigger detriment to casting low, and a bigger bonus for casting high (though Necromancers still get a bit more bang for their buck.)
The integrity of the spell also now modifies the warrior's defenses.
