Trying to think of a way to make a class that specializes in one weapon type, but has a sub-weapon type that they can learn and master, so basically able to use two different types. For example, say a main weapon as a sword, and sub-main as say guns? I have an idea on how to do it, but any advice would be very helpful on this.

Alongside that, when specializing in a weapon type say a blade, the weapon comes with a special ability (perhaps unique to the user) that levels with the player and thus a new weapon isn't needed, maybe these weapons like normal could be enhanced with something like blacksmithing? Dunno, any help/ideas all?

With reading the CS template again, and seeing, if we're allowing sub-tiers for main classes, perhaps these special abilities from this idea could be leveled within those sub-tiers as they grow, making for a complex and hard to play class that many many people avoid?
