I think that the best weapons for tunnel-like enviroment would be spears, since your opponent lacks space to maneouver out of the way of your thrusts. Two-handed weapons like glaives don't make much sense for me, they need space to wield properly. IMHO, space is something that a giant race might lack in tunnels.

I think that like 50% of mages carry stupid equipment. Daggers? Quaterstaff is same resourcecost, and gives that sweet +3 bonus defense and some lenght. It also looks much more better.
