I was just typing some more thoughts up, but I think LibraryLass's tables might be better.
Here's a continuation of the Wpns vs AC concept. (No AD&D tables this time, sorry about that)

Further random thoughts on specialising weapons against armour (please ignore if going totally off-topic!). This is based more on cliche and personal assumptions than battlefield reality.
"Bludgeoning" weapons (maces, flails) are good for smashing against plate / and perhaps against chainmail (?) "Piercing" (spears, arrows, bolts, bullets) are good against leather and hide, okay vs chain. "Slashing" weapons (swords) are good against leather, okay or poor vs chain, poor verses plate. Maybe Bludgeon can be poor against leather or monster hide? Axes are classed as bludgeon in some systems (MERP), here I might treat them as "slash".
So my table of adjustments to the hit roll might look like this:
Code: Select all
Leather* / Chain /Plate
Bludgeon 0 / 0 / +1
Pierce +1 / 0 / -1
Slash +1 / 0 / -1
*also monster hide
It's far from perfect, it's a generalised approach. I'm keeping the adjustments low so not to detract from the majesty of magic weapons. At least it brings a little respect to the humble mace.
