And the definitions of each trait:
Armor Penetration. Whether through precision, penetrating power, or blunt force trauma, this weapon grants a +1 to hit foes in medium armor and +2 against heavy armor.So these weapons cover a lot of ground with many different combinations of size, damage, and traits. One aspect that isn't apparent here is cost and quality. The weapons that are derived from agricultural tools (scythe, pitchfork, pick, and machete) are clearly inferior weapon choices when it comes to comparable weapons' damage, size, and traits. However, being weapons adapted from tools, they are significantly cheaper and only come in lower quality. They represent peasant weapons and are a cheap way to arm fodder and hirelings.
Catches Riders. When used to dismount a rider, automatically succeeds on a successful to-hit (defender may not choose to take damage instead).
Defensive. Grants user a 1 point improvement on Armor Class.
Ignores Shields. This weapon strikes over or around shields, negating their defensive benefits.
Light. Balanced for throwing and may be dual wielded in the off hand.
Long. Ill-suited for melee combat; this weapon may only strike in the first round of a melee. Does not apply when wielding from back ranks.
Pike. Grants +2 on morale checks when resolving charges.
Reach. Reach, followed by a number, is the rank that a weapon may hit from.
Two Handed. Despite being 3' in size, this weapon requires 2 hands to be wielded effectively.
Every weapon should fill a niche. No one weapon is ideal in all situations and they each have strengths and weaknesses. Whereas a great sword has the best damage output, a poleaxe or halberd would be better suited for a mounted, armored opponent.
If anyone spots a weapon that is clearly superior in multiple/all situations, let me know so I can tweak the numbers. If anyone wants to discuss how some weapons are unique, please feel free to chime in. This weapon list is still living and I might decide to add some more exotic weapons from outside mainstream European use. Plus, I also want to tackle thrown weapons and ranged weapons and give them a similar treatment. And I have a few ideas for shield use as well, none of which are original.
EDIT: Pursuant to the comments below and further thought, battle axes inflict 1d10 damage and short spears are not considered Light weapons. Short spears may be thrown but can not be dual wielded.
