Hey DL players, so...I'm a noob when it comes to farming relics. I just have a few questions for [awesome] people that have already obtained relic weapons and gems in the past. I'd greatly appreciate all of your responses. ^_^

1) Which location(s) is best for farming relics?
2) I've heard that Harg'kyth drops relics, but only if you don't break the stones, is this true? Plus, how does one defeat Harg'kyth without breaking the stones around him? I've tried it countless of times, but it's virtually impossible for me to do so. Is there a certain build for defeating him?
3) Any extra tips and suggestions?
