The Surge technique says it boosts the user's "Wisdom". Is this supposed to say "Intellect"? (Since "Wise2" is a spell that boosts Intellect.)
Also I'm occasionally, though rarely, getting a bug(?) where I can't change which ally I target with a healing spell. I'm not sure if it has anything to do with my usual tactic of having my two fastest characters put all the enemies to sleep, then replenishing MP by defending. When I win and then go into another battle, this odd effect is gone.
Also there are occasional oddities where there's an object I can't pass through that doesn't seem like it ought to be there. For example, in Deepforge III, there are two tiles beneath the stairs down from the King's house that have walls on them, subtly indicated. Also I think there's a thing behind one of the trees at the bottom of the screen near Malady's house. I'm not sure whether they're concealing secrets I ought to look further to find.
Also it seems the Medic shield's HP restoration replaces the usual MP restoration of the Defend command, rather than being in addition to it as your guide says. (Also in the same part of the guide, the monster is Z-Wolf, not Z-Alpha.)
