Utterly impossible. Tons of oils, with spikes and fire traps in the room. This is mostly a complaint about the oil enemies, which move lightning fast, do huge damage, and, apparently, can't be shield pushed (so they just cornered me and had their way with me). That's before they start lighting everything on fire also.
I'm all for challenge, but this room was utterly unforgiving in every way. This is coming from someone that has frequently successfully soloed T3 danger rooms.
I love that room. It's difficult, but you should expect that from something called a "danger room."
I recommend the blast bomb series in there. It'll keep distance between you and your enemies, push them away before they burn you or catch you on fire, and damage many of them in each explosion.
I also recommend bringing at least one other person with you, with complementary weapons (perhaps freezing and poison weapons). While you can play this game solo, you're not meant to do so easily, especially in danger rooms.
