Hocus-Pocus

If only we could get Catherina to shoot at their base... Ah, that's impossible.
However, I'm pretty sure I can disable the shield above their base. We will need several trionic crystals for that.
Could you bring me some? They used to extract them in the quarry to the west of this forest. I bet you can still find a few there.

Bring me several trionic crystals. My hocus-pocus requires them!

Let me see... Yes, that's exactly what I need! Now we have to come up with the attack plan with Sidor.
