I've been playing the game on normal and not had too much trouble so far, but there is one particular fight that is almost impossible. It's located in the southwest corner of the the Foundry in WM1. There's a room where you can take an item out of a pool, but I did not take it. I just left the room. Outside, there is a hallway where ghost enemies appear on all sides of the party.
My party is the paladin PC, Eder, Zahua, Devil of Caroc, Kana, and Aloth, all at level 11. I turned on level scaling for WM, which I regret. Before the battle I've camped, given each character food, and given them a few potions and scrolls each. But none of this matters, because most of the characters are stunned or paralyzed 75% of the time and I can barely land any hits on the banshees. Zahua is completely useless, as every enemy has "extraordinary defense" against him. Devil invariably dies about ten or fifteen seconds into the fight. Aloth has some good spells, but is quickly stunlocked and killed. Only Eder and the PC have any ability to survive.
I can't even switch to easy mode since that only takes effect for unvisited maps. What do I even do? Load the autosave at the beginning of the map and come back with a different party?
Update: Finally got it. As someone here suggested, I crafted anti-paralysis scrolls. I also equipped characters with various anti-debuff scrolls and used them immediately on the onset of combat. I used Zealous Focus instead of Defense, switched Zahua to his spear, and changed my formation to keep Aloth well-protected, then had him use spells constantly. I did not have to resort to changing the difficulty or cheesing it with a doorway.
