I see also i can't defeat Ayleen yet do i need to get stronger or?
Not necessarily get stronger, this game doesn't require grinding much or at all. I'd recommend:
1.Setting your difficulty to the lowest if you're having issues defeating anyone.
2.Using the Skill 'Fumigate' (that you learn from reading her book when you first encounter her) as soon as she has used either of her two status moves twice, as getting to a third level with either status is pretty much an instant loss. I don't remember the name of the status, but one is pink and looks like hypnosis and the other is blue and is pretty much paralysis.
3. Ayleen doesn't use seduction moves or moves that can be avoided by being focused, so the 'calm down' and 'focus' skills are useless with her. Use those turns to do other things.
The rest is pretty much standard for all fights. Getting a weapon that has a move that can stun is pretty good, as it usually lets you stunlock opponents. You can grind Vidhna if you feel like grinding, as the weapon you can craft from her materials lets you stunlock. Manage your energy levels (the white circles on the left of the screen) so that you can dish out huge damage with explosion but can still heal when you get to low health. There's a skill that lets you get two of those energy levels that you learn when you meet Ayleen, which is called 'Scattershot'. You should be able to defeat her relatively easily by using those strategies.
