Valhalla is cool in concept but right now only useful to certain people
Right now, there's a few limitations
In no particular order
#1. Shooting/archery is not granted. -Easy fix, but please give Archery to everyone.
#2. Gear levels are not good for testing, and are subpar in relation to overworld. - There should be "Equipment" vendors in the Great hall that give one of each equipment, rather than the littered weapons (Although it is neat) we have now. They should vend at specific quality levels of 10, 40, 90 and possibly 160. There should also be more gear, such as Lynx capes and other stat-buffing gear.
#3. Moves are limited to what you had in your old life. You should be able to read books or somesuch to learn attack moves as you desire, perhaps another vendor inside the great hall.
Other things as well
#4 You can't hearth back. You should allow hearthing to the big fire for convenience.
#5 Food only raises by 10/1, can you give a food eating option that raises by 50 or 100?
#6 Add a food type that raises marksman/perception (For when perception is relevant to combat again.)
