Well, I normally have few problems with the last battle of the game, but I keep getting defeated repeatedly by Remedi in her Li-Grim form. My units are around Level 23 to 26, and I'm equipping them with the most powerful nonelemental weapons they can have. But I keep getting destroyed by Remedi in the first turn, because she uses Descent, which sends out Mateus/Adrammelech, which KO's my entire party except my Defender. Then the Mateus' finish him off with Star Cross before he can do anything. Is there any good way to counter this?
