DM's are willing to help in this I've found, even, shockingly, in the even of someone evil destroying a relic from a goodly inclined faith too
But, I think the gist of the origional post was to see if it was possible for it to be done
without DM assistance. I think though, destroying artefacts and relics and things is a little bit bigger than breaking a chair though, since there are powers at work here that may want to take action upon the breaker.
