Had a very tough time with Haukke manor with a relatively well geared group. Perhaps we did not understand the mechanics of the last boss but two ranged dps classes in their relic weapon should not be barely doing enough damage not to wipe on blood rain.

There are multiple jewellery drops per run through there so you can acquire ilvl 60 jewellery easier than you could with AK.Though if you're getting that far in, you may not even need any of the gear.
