Wizardry Gaiden 3 still (though I'm thinking of starting one of the Wizardry Empire games soon). In the first part of the final main quest dungeon, and I'm earning a lot of XP, but there is one particular enemy (that looks like a blob with eyes) that is, perhaps, bordering on unfair. In particular:
* It appears in large groups (I think I've actually seen 9).
* They have a breath attack that, in addition to doing significant damage, can cause petrification, which can only be cured (on one character at a time) with MADI; the multi-target status cure will not cure it.
* MATOKANI (kills weaker enemies) doesn't work on them.
* TILTOWAIT (most powerful attack spell) *sometimes *works.
* CORTU (supposed to improve your resistance to spells and breath attacks) would be a good idea if it works, but unfortunately the spell doesn't work in this game; instead, it makes *your* spells less effective.
* Physical attacks work, but there is no way to kill more than 6 in a round this way (since you only have 6 characters max, summons don't persist between battles, and there are no multi-target physical attacks).
As you can see, there's no way to reliably deal with this particular enemy.
(At least it isn't as bad as the Archer Polete enemy in Elminage Gothic's postgame; that enemy is just ridiculous, and there's an even stronger version that's been known to wipe out parties with levels in the hundreds.)
