Blasting anything in a cave sounds like a bad idea anyway. If you want to take the crystals, then I will not stop you [she is not sure if she could in her condition, though she did train with a blindfold on before].

Once you have what you want, I would be grateful if you would lead the way to the left, though. It seems that the right has those tools and is lower down. Also, the ground slopes up to the left and the air feels fresher.
