I need some help power is over a 100 was able to choose hesitate that way got all possible Daryl points during the fight lauries head still went boom.
You also need 28+ skill and choosing to break the Blue Sword.
Choosing to break the sword is simple.
However to get the skill you need to do some things right:
I'm not 100% sure about, this, but there should be 5 missable skill points before the Diamond Battle.
1 from sparring with Michael (very early in the game, choice between +1 Power or +1 Skill, I recommend getting Power)
2 from training against Minyaks
1 from sparring with Laurie
1 from sparring with Tiffany
If you have done everything correctly, you should have either 26 or 27 skill by the time you start the Diamond Battle.
The game offers you one more skill powerup (+3) before the Deryl fight
This means that if you have missed skill points and start the battle with 24, you can't save her.
Otherwise, you have the following options:
Case 1:
If you choose to fight the Wepwawet (choosing to follow the Right tunnel), and choose to "Try to overcome it's power", you will gain +5 Power/+3 Skill.
If you make this choice, you don't need 100 Power to hesitate against Deryl. You beat the check anyway.
Case 2:
If you choose to meet Aglaecwif (choosing to follow the Left tunnel), you don't gain any stats unless you ask for them. You have the choice of either +10 Power or +3 Skill. You have to choose Skill to save Laurie.
