What would you recommend for final dungeon /boss? *SPOILERS*

Hello, there.
I really love this game, but I'm almost at the end, and I'm getting a little frustrated near the end point.
(Apologies for not getting the character's names. It's been awhile since I've played, and I forgot their names at the moment.)
I know with the final boss, you *SPOILERS*
...Sort of lose a party member *ahem*, and then the rest of the team fight into what seems like two separate groups against the boss.
My first group didn't have too much problems because of the magic and status effects and strong king character and main queen character, but my second group really, really struggled and died. The second group had more trouble probably because I didn't use the mage/wizard character that much. He was level 14 or 17. Really low.
However, even with the second group being somewhat levelled up a little tiny bit more, I'm also having trouble with the equipment. Is it better to have the mage/wizard person with a wand with less attacking power, but with confusion/status effects, or is it better to equip him with the stronger wand? I also have trouble on what to equip the characters with spears, too.
What levels would you recommend for the final dungeon? What equipment works for you? Particularly for the second group (with the mage and spear guy) the goes against the final boss?
Any tips would be greatly appreciated.
