Additionally, to counter monsters not being able to avoid damage through resists the way they do with poopy throwables like caltrops...

:idea: Would it be possible to make caltrops poisonable? Would that even work if the caltrop damage isn't getting through the DR?

Caltrops as they are do cause damage like getting asbestos under the skin. :P Also if pcs have them NPcs will too.
So people will need to stock up on more potions and bandages if this goes into effect.
