There is nothing more satisfying than soloing with the 6 classes and hitting 50, but I did play with Dililah with my Spirit Born for 2 levels. Things were moving so fast I did not have time to and swap out my weapons and armor and temper them. At 42 level in the Pit I did a little killing then I had to stop or its game over she kept going I hit 43. RIP Dililah you will surely be missed thanks for the level up! 4 classes Teir 2 and 3, but the Druid died 5 times in a hour so he was Teir 1 until 50 Teir 3 same with the Barbian. These were all my own original builds. Last year when I first tried too many deaths under 20, except with Necromancer it was glitching out so I deleted him at Tier 20. After just learn as you go a year later 100% doable.
