So, I was curious after soloing Scalecaller Peak... Which dungeons actually cannot be solo'd due to mechanics? I only know Fungal Grotto 2 off the top of my head due to the instant kill mechanic a boss has (and there is no way of a companion actually being of any use in that situation), but is there any other?
I've been thinking of going through dungeons one by one as a solo (with a companion as a healer though) so trying to remember all the different dungeons and their mechanics right now to know which one I shouldn't waste time in trying.
