How many times have you had to choose between practicality and looks? Many times.
Paired weapons look so much better! Because symmetry. Two daggers, two rapiers, two swords.. you name it. But it's often not mechanically practical without specific talents. And even then it's subpar when you find certain weapons.
If you want to be a dual wielding adventurer who adventures with style, this small modification to the talent is absolutely necessary.
+5 to accuracy if you wield the same weapon type in both hands and have the TWS talent.
Thx, bye.
