So, dwarves have two arms. Dwarves strike with one weapon at a time. This is because the majority of dwarves are left or right handed. But couldn't we train them in some form duel wielding? Korea used dual wielding extensively, Japanese samurai were taught to dual wield, the Mamluk had duel wielding, and Shikendo contains duel wielding a pair of full sized swords. Yes, it's normally played for looks in anime and gaming industries. Yes, Korea eventually phased it out after a few hundred years. Yes, Samurai normally fought with one sword. But it was used historically. My proposition is a skill and physical trait to go with dual wielding. An ambidextrous dwarf would have something mentioning it in his description. Only a dwarf who's ambidextrous would be able to get the dual wielding skill, and would, in combat, use both hands' weapons. Slash with the sword, then bash with his shield, in the same move. Quite like how you can lineup your adventurer to kick and punch twice, bite, and strike with whatever is in each hand all in one turn, but less overkill. Only 3% of the world is ambidextrous. Out of a 200 dwarf fort, that's 0-6, maybe more, dwarves who are ambidextrous. A dwarf who reaches legendary dual wielding will be just like a legendary fighter who's a novice swordsman, just a swordsman. A legendary dual wielding swordsman would be a legendary swordsman. Train him to legendary in two different weapons, and he'll be a weapon master. Still, get an ambidextrous dwarf, give him a hammer and pick, and let him loose on the enemy. What do you think of the idea?
