Asumming they didn't change the properties of Witch Kabobs they add 15 MP 4MND HealingMP+3 and last for 1 hr. These are what i have always used as whm or smn. HQ pies add hMP mp and int.
the best food for a whm or smn is probably Mushroom or Which Stew. 20/25 MP -4/5 str +6/7 MND hMP+ 4/5. Again, this is assuming that the properties of these foods were not changed...
Wish someone would post how they find this info out '-';; it would be nice to be able to research these things without depending on other sources
