Possible bug in 2.28 beta. Creating a hexblade warlock, and found giving him the Arcana skill was resulting in the wrong amount. (used Int 10, proficient in Arcana, resulting in a +4 when it should have been a +2).
Also, I saw the proficiency issue with martial weapons was already mentioned...
Federal Way might be a bit far, but I know we keep getting a lot of interest at Heroic Knight games in Issaquah, and just don't have the DMs to keep up. You might check out their facebook page too look for interest.
