It’s not tremendously hard, there aren’t any nodes that make fights restrictive, so if you have your basic fighting fundamentals down, you could technically do it with a 2* SL
I do it with R5 4* Warlock, R4 5* Blade, R3 5* Vision Aarkus, R5 4* Iceman and R4 5* Ghost Rider. I believe I've enough skill to do it without too much spending, it is up to you to rate your own.
I just completed my first rift with the boys. It was ok but still block damage takes 1 perecnt health per hit. The boss (black widow do) was easily destroyed by my 5/50 iceman. The adaptoids were a little hard because I had problems dexing the cyclops laser beam and usually got hit but was a great rift. Luckily got a 5 star mystic awakening gem and used it on my claire voyant which was awesome.

But block dmg is a concern
