The good news is that (other than the pain) it is completely harmless.

The way it always felt to me is like someone wrapped a small wire around something tender in my chest, and if I tried to breathe or straighten my posture, they would yank on it. I'd get it anywhere from a couple times a week to once a month. Then one day in my mid-30s it just stopped.

From what I understand this is relatively common. I was so grateful for the person on reddit who dropped this nugget of wisdom several years ago. It was nice to know I wasn't dying or whatever.

If you ever needed a sign to stop using reddit, this is it.

Here's a nice explanation from /u/gameryamen on reddit:

Say you have a flat arrow pointing up. You spin it 3/4ths of a rotation clockwise, so it's pointing to the left. The simple way to undo that rotation (meaning, get back to the starting point) is to simple rotate it counter clockwise the same amount. But another way to do it is to rotate it 1/4 of a turn clockwise.

Another way to describe that last 1/4 turn is as two 1/8th turns, right? We're scaling the amount of rotation down, then doing it twice. The factor we need to scale down by is pretty easy to work out in this simple example, but it's much harder when you're working in 3D, and working with a sequence of rotations.

However, this paper shows that for almost all possible sets of rotations in 3D space, there is some factor by which you can scale all of those rotations, then repeat them twice, and you'll wind back up at the starting position. A key thing here is that we still have to find or calculate what that factor is, it's going to be a very specific number based on the set of rotations, not any kind of constant.

Why does that matter? Well, besides just being a neat thing, it might lead to improvements in systems that operate in 3D spaces. Doing the two 1/8th turns takes less work than doing a backwards 3/4ths turn. Even better, it allows us to keep rotating in the same direction and get back to the start. If calculating the right scaling factor is easy enough, this could save us a bunch of engineering work.

Edit: The most common question is "why do two 1/8th rotations instead of just one 1/4 rotation?" The reason is because the paper deals with a sequence of rotations in 3D, not a single rotation in 2D. But that's kinda hard to wrap your head around without visuals. This is going to be a little tortured, but stop thinking about rotations and imagine you're playing golf. You could get a hole in one, but that's really hard. A barely easier task would be aiming for a spot where you could get exactly halfway to the hole, because you could just repeat that shot to reach the hole. There's still only one place that first shot can land for that to work, it still takes a lot of precision.

But if you change your plan to "Take a first shot, then two equal but smaller shots", there's a lot more spots the first shot could land where that plan results in reaching the hole on your third shot. Having one more shot in your follow up acts as kind of a hinge, opening up more possibilities. This is what the "two rotations" is doing in the paper, it's the key insight that let the researchers find a pattern that always works.

After noticing the debuff, I got in contact with a level 56 healer and he said there is no way to remove or even weaken it. Other players with this debuff usually run out of max HP in a couple years. They can still log in, but there's not much point because the debuff drains their STR and DEX so much they can't even defeat a level 1 crab anymore.

Why did the devs add random debuffs to the game that make your character unplayable? Don't they want players to keep logging in? I could understand if my character got hit by a hex from a high-level warlock in PvP, but completely random debuffs?

Are there any high-level priests here who know whether we get sent back to the character creation screen when our character runs out of HP? I never understood why this game only has one character slot. I could just switch to an alt. Hopefully I'll be able to play a better game next time, because let's face it: this one isn't that fun.
