What are the best areas to farm Vaal Side areas?

[Oni]

Need to kill the remaining bosses.

[Awesome!]

vaal bosses are linked to certain vaal areas which only spawn in certain zones. easiest thing to do is look up the boss you need on the wiki (https://pathofexile.gamepedia.com/Path_of_Exile_Wiki) and it will tell you the area you need to be in.

alternatively you can just hope to get lucky with sacrifice fragments in your map device

Thanks :)

Hey, I'm all about helping (guildmate or not), glad you did found the info prior to this list :)

You're welcome to have taken the time to thank me even though it was of no use to you :)

Happy gaming!

Easiest way would be to farm somewhere that is a nice linear map and quick, the spawn rates of the side areas is around 1 in 10, once you get a dozen sacrafice fragments you can start farming them, they are prety close to being sefl sustaining when you use then via the map device as you are more likely to get another fragment than a vaal gem.
