I was in the middle of a battle and for some reason, it won't allow me to use any weapons or scrolls for my turn. It won't allow me to select anything. Is this a glitch or is this just something that happens that I don't know about because I'm a newb? Thanks in advance.

Some opponents can disable weapons and/or scrolls, it's definitely not a glitch!

If you can't use a scroll and weapon you might be frozen in battle. Have you seen a snowflake under your pets health bar?

and Thanks for letting me know. I think that's exactly what happened. Now I feel stupid for asking!
