Had a really fun run yesterday:
Ozmone Plains (I think it's called) I was lvl 20 (I level up every character at the same time) and found another entrance to the Zertinan Cavern BUT this sector was hell, I barely could kill a horse (Mallicants) and the place was full of them, GLADLY! Espers really work in this version and Belias could manage to clear the first section with some effort.
The second section I fought a Tortoise that killed 4 of my characters an I ran off of Phoenix Downs. After that I had to steal in first attempt a Phoenix Down from a Mallicant, revive Penelo (who's the only one with Raise magic) and revive the rest of the team an keep Penelo alive at all cost so I set Gambits to heal Penelo whenever the enemy focused her.
I got to summon Belias again and reach the Adramelecht boss battle but it was impossible, I manage to take half of his life with Hellfire and Quickenings but I couldn't stand the undead, they kept respawning and their magic wrecked me.
I had to flee through the whole dungeon and managed to do it with just 3 characters (Penelo died again). Eventually I arrived to Jahara, recovered my team and got new equipment and licenses.
After the next story bit I'll fight my way to Adrameletch again!
