Hey guys,
All of your answers last time were great. Have a few more questions if anyone is open to responding.
-How do I use the catalysts? I've attached some images to give an idea of what I have. They're there, but I don't understand how to get them.



-What's XP? I have a few XP boosts, but I don't understand what they're good for.
-I've been told that Dexterity is a good Mastery boost to have, but I'm not sure how I can attain it. I have three Mastery points that I can use, but when I go to Utility to get it, the button to get it is dim.
Thanks for all your help last time guys, appreciate it!
