Very easily done, especially with the stuff in Iron Heroes. Since armour provides a die, rather than a set DR, it's quite possible for a dagger to do some damage. As an example, studded leather is DR 1d3/magic, whilst plate is 1d8/magic.The_Gneech said:I like the "armor = DR" option myself, but there has to be a way for finessing low-damage types to bypass it (via some kind of to-hit penalty or an armor-piercing option, etc.).
Merlion said:Armor doesnt make you harder to hit, it prevents damage.
Having the type of damage make a difference would add realism, but also a lot more bookeeping and whatnot.
There should also be a class-based Defense bonus that does make you harder to hit
All historical fighting style that I know of study how to strike where the armor doesn't protect. Not how to strike so hard that you go through. However, some specifically designed weapons tend to "ignore" armor all together. IMO, YMMV and all the acronyms you want if one does not agree with me
