i took my wizard into the first quest 'the archons trial' on eh and it was slow as i expected. dretchs, archons, jariliths and hezorus immune to my primary spell type electric so fights were typically energy burst the few tieflings, renders and abashi and then neg the hezorus then wail and circle of death to death with the rest of them.
i did note the trapsmiths path for the extra chest the first door i was able to knock first time(didnt see what i rolled), the second door dc i needed a 19+52 and the 3rd i could not open on a 20 but was able to bell it so likely the dcs for the door are 65,70,75 on eh or something similar
so eventually i was able to make it to the end, pretty straight forward quest but the final trial was room was full of archons, immune to all spell types and very high spell resistance, all while spamming commetfall and bladebarrier but luckily no divine punishment. so pretty much i only had my necrotic ray and negative slas to kill 5(?) archons and died once in the process. when it was just the boss left i was able to just face tank it with my aura and occasional negative burst but with only negative spells doing damage it took about 10 mins to kill the red name alone.
i decided to roll a barbarian for the 2nd and 3rd quest.
