*All iron weapons on display above
Each weapon has a unique crafting recipe using at least a block of it's material which sounds expensive and it is; but it's worth it! They have high durabilities and something called traits! Traits are shown in the tooltips and give weapons unique properties depending on which they have:
Armour peircing: reduces armour damage reduction
Two-handed: gives a damage boost if you have an empty offhand
Hard strike: reduces opponent's movement speed after hit
Rageful: finishes off mobs anyway even if they have higher HP than the weapon's damage
Weapons in this mod usually have 1-3 traits depending on the kind. There are multiple levels of them that are more powerful the higher the trait level. For example, if a weapon has armour peircing 1 and another has armour peircing 2, the weapon with armour peircing 2 will be more effective against armoured opponents.
