So the text of Jagged Berms gives an AC, a Hardness, and a HP value - but no Broken Threshold.
Do items/creatures with a Hardness automatically *have* a BT? If Berms do, what happens when it gains the Broken condition? A result is given in the text for Destroyed ("Becomes difficult terrain"), but nothing for broken. OR, do the Berms not have a BT, because none is listed, and nothing happens until they are destroyed?
If I am missing any key rules someplace, please enlighten me!
