Hmm, seems like you are in luck...or maybe it is me that is in luck, but anyway, there is an event scheduled for this weekend
Ranger Event if you can make it. It is for rangers and will include things like
Stealth/Concealment/Cover and how to roleplay it (I think the mechanics are easily abused and would like to get people to expand on the ability). Also, there will be the use of summons/companions and how to control them and emote with them. These are just a couple of examples, I plan on other people providing questions and lessons learned to better the event. Oh, if you like, your son's character can tag along as well no matter what class his PC is.
Welcome to Layo!
