[@LetMeDoStuff] I also have a question about crystals. Are we stuck with just one, or can we just grab whatever before we head out. Like if I put a fire crystal in the lance, am I stuck with it, or can I take it out and grab an ice crystal?

You theoretically can but whatever you want into it, but like the previous question, the weapon would become somewhat unstable and the elements would mix badly. Most servicemen will generally use on!y one, but those who switch them usually wait a few days before switching them over. However, I won't stop you from changing them in the fly, just as long as you know the slightly bad side effects
