Etrian odyssey IV's first wall

I own the original Etrian odyssey game, Etrian odyssey 3, and Etrian odyssey 4. I have yet to beat any of them. I have come close in the first game but the data got corrupted when I cheated on it- and I had to restart (WHICH IS WHY YOU SHOULDN'T CHEAT IN GAMES).

I really want to beat one of them. My etrian odyssey 3 team is a very safe team and got me far in the game, but I got bored playing them. Then I got etrian odyssey 4 for Christmas last year...and I decided this was going to be the first etrian odyssey game I was going to beat.

I went into the first boss battle (the last one of lush woodlands) after spoiling it for myself online. I was both over leveled and everyone had the best gear they could possibly get. The boss fight was really really easy. So I told myself I wouldn't spoil the 2nd major boss (of the Misty Ravine), and I didn't I went into the boss battle blind.

My party was:
*front line* Calypso (Nightstalker)- Aurelia (Dancer)- Mania (Nightstalker)
*back line* Liz (Fortress) - Kaneris (Rune Master)- GuestNPC (first unlockable class)

...yes that's right I had no white mage/medic in my party. And to put that party in latale terms:
RM- Popstar (minus good healing skills)-RM
Holy Order- Archmage- Archmage

spoilers on the 2nd major boss battle below

Latale Infinity

So latale got a years worth of content in one patch and yes I do still play latale. I checked out my archmage/phantom mage's damage before running off to make a card master and I have to say it seemed to decrease.

This is a wall of text below the cut.
