Melee weapons are close-range styled weapons. Some melee weapons have enough power to kill an opponent with a single thrust into the head or anywhere on the body.
Melee weapons come with two functions. Standard Attack will give you a hasty attack which can be repeated rapidly. However, Heavy Attack gives you a much more powerful, yet lengthy to execute attack.
Melee weapons aren't too heavy but can be a bit tricky to use since each of them requires timing for you to use them. However, melee weapons are close range weapons, as a result, this puts you at a severe disadvantage if the target is out of the melee range.
