The class feature Combat Training states: You ignore burden when equipping weapons. When you deal physical damage, you gain a bonus to your damage roll equal to your level.
Creating an Agility based Simiah “Call of the Brave” warrior and it will not allow me to equip a longsword as primary and a short sword as secondary. Under the equipment tab I can only have one “on” at a time. I am assuming it isn’t allowing the two-handed longsword to ignore burden.
So, when I first attempted this I had the exact same thing happen. However, after bringing it up with one of our devs it magically seems to have started working properly. I’m going to link your character back to you, I didn’t make any changes to them other than to equip both weapons, if you’re still having trouble with your character sheet you should feel free to make a copy from the one I link.
