Leonardo's equip: Diamond Knuckles, Phoenix Headdress, Winged Armour & Fire Rune
Jessica's is: Chakra Wheel, Winged shield, kit's bandana, Dragon dress & mind Rune. Maximuss is: Triton's Trident, Cross shield, Knight's helmet, Paladin armour & Iron rune and Leah has Spear of Destiny, Shadow shield, Hobo Lily, Venus Bikini & Earth rune.
With only the Diamond Knuckles, Leonardo will probably have to resort to being a support character in this battle.
However, Jessica's Chakra Wheel can actually deal some pretty decent damage with a little assistance. Do you have any accessories like the Megalodon Tooth, Battle Scarf, or the Ogre Badge you get when you return all of Ben's statues to him? You could try equipping those on any of your characters and see if you deal more damage. Of course, you'll be sacrificing Elemental resistance in exchange.
I know going back could be a nightmare, but if you can nab another Shrine Key, Maximus could really benefit from the Seraph Halberd you can get on the Strength path of the shrine.
Leah's setup is very good; the only thing you might change is an accessory that boosts her Attack even more, but of course she won't be as well-protected without her Rune.
If you do go back, remember to stock up on all the items I mentioned.
In any case, good luck, and thanks for your encouragement.
EDIT/PS: If you have Genbu's Shield, that's something else that could help increase your damage output.
One more thing. What is the biggest problem you're having? Not dealing enough damage? The boss dealing too much damage to you? The battle simply going on to long and running out of resources? Or?
