Finally got around to doing Underkeep last night and I think this might be where I finally just stop playing. I literally had to force quit out of the game when I was expected to immediately do the trial afterward (couldn't anyway bc ilvl, but it left me zoomed in on the bright flashing summoning circle) because the resulting migraine and nausea were so bad I couldn't stay in my chair. I had to turn all the lights in my room off, lie down, and wait for the episode to pass. I can't go back in there to farm it, so it's going to take forever to get the gear to do the trial, which is likely going to be just as dangerous for me to do.
The overwhelm is so bad now, I dread doing any kind of group content.I fudged Heritage Found by keeping the camera pointed at the ground or just skipping the area when I could, but dungeons and trials (godsdamn I hate trials so much) are mandatory and require me to somehow look in every direction at once with everything strobing in a demand for attention, even with other players' effect off. I got violently sick trying to farm Vanguard (the point where EW's augment gear needs upgrading) a few months ago and can't go in there anymore. Basically, anything lightning themed from this expansion is the biggest trigger. I don't know what to do anymore.
