I was reading through the Necro vs Empath pet thread in the Necro folders and I came across this comment from a poster:

>> GMs confirmed on Test that pets are based on mana and TM for casting, not stats. Stat boosters and or BUE don't effect them.

Is this true? I thought Vigor was one of our spells we were supposed to be able to cast on our guardian to make them better. If this is true, I'll just stop wasting my time buffing them then.
