One of my players plays a grapple-oriented barbarian, and would like to get something more badass than common manacles or silk rope to tie up stuff with. We were thinking about magically treated rope or adamantine chains/manacles.
Are there any supplements or rules which has guidelines for this? I haven't been able to find a guideline for Break DCs in the PRD from knowing the hardness and hp of the material.
If not, anyone have a good idea about costs and DC limits?
There are not rules for it. I would increase the break DC by 5 for adamantine chains which would put it at 33. I would price them at 200. The hardness would increase to 15 and the HP would go up to 20.
