I was talking to a friend of mine about our games, and I was telling him how I was glad my DM had let me switch out the two normal +1 abilities you get from the bow of wintermoon (drow band and frost) for the straight up +2 force ability. If he hadn't, my character would have been completely and utterly useless in our game with all that incredibly high DR that we see on a regular basis.
Then we got to talking about how there's all these weapon abilities, or spells, or feats, or class special abilities that temporarily lower an opponents SR and PR. Like Shattermantle will lower an SR by 2 for every hit you make for 1 round. A Slayer, at lvl 8, get Breach Power Resistance which lowers by 1 for up to 12 hours. Then we wondered. Can you do that with DR too? Is there a feat, or an ability that lets you temporarily get through DR? Think about it. No matter how hard something is, eventually you have to crack its shell. Sparks might fly for a bit, but eventually you're going to find a chink in the armour. Like say the sunder ability. You slowly destroy armour and weapons. Why not sunder DR too? Or have an ability that mimics that. Anyone know if something like that exists?
