I tried looking on the wiki to try and figure out how to destroy a hearthfire that is not your own, but there's nothing for a Hafen fire, just the legacy Haven one. I knew how to break one back in legacy, but I don't know how to do it now. It's on my claim, full authority, and I go to destroy it, it tells me I'm not strong enough.
I know that's likely my issue right there..but, that being said, how much strength do I need? Back in Legacy, I used to be able to do it if I hacked away at it long enough and kept drinking up some water..
