Is there a way we can destroy these crystals? I can't seem to make a dent...

It's impossible to destroy these tough crystals with just a regular attack. You'll only deal a bit of damage.

What should I do?

From personal experience, we need only attack it ten times, and the force field will be weakened, then the crystal shall be purified and destroyed.

Kroos will help you out with her fast attack speed!

Here I am!
