our only tools for war are swords and bows. We need more, we need a Spear/pike and a shield. Parrys with a sword...just dont work well enough so i think having a shield in one arm to use via left click would be awesome! and a spear to hit those mobs from a distance (2 blocks or more away) its a much safer alternative.
how a spear could be made,
2 blocks going up or down diagonally, with either gold, wood, stone, iron or diamond tips
shields could be like a door or iron door but with 1 piece of wood, iron etc to the side.
