i found an issue where because witches lock on, you can all four lock on you but have to wait and then all we follow few steps, just have to keep aggro and then easily collect all orbs also i have noticed DPhantom that you are faster so can lose aggro, issue is they automatically go onto move pattern they were on before saw you so then you get trapped but witch didn't actually know you were in that corridor so i suggest after witch loses aggro it should move complete opposite directions so doesn't feel lucky dependent also found out 2 of witches spawn in same place and at same time so watchout for that one
