This is an environmental particle put in by the file
qeytoqrg_environmentemitters.txt. (
qeytoqrg stands for "Qeynos to Qeynos Ranger Guild"—in other words, Qeynos Hills.) Environment emitter files were introduced at some point ~10 years ago in EQ to allow Sony devs the freedom to put new particles in any zone to depict things like mist, fire, magical portals, and even bugs (like the butterflies seen at the
char select). I have no idea what this blue thing outside of Blackburrow was ever used for, but I'm pretty sure it is nothing more than a holdover from Live.
I see the following text in
qeytoqrg_environmentemitters.txt:
Code:
Name^EmitterDefIdx^X^Y^Z^Lifespan
void_a_151^261^3388.676514^-1006.737915^-1.000000^4000000
void_b_150^260^3388.676514^-1006.738342^4.533447^4000000
void_b_15050^259^3388.676514^-1006.738281^-1.000000^4000000
If you were to delete those three
void lines (or the entire file) and then relog, the blue shimmer should vanish.
There are similar oddities in other zones, like floating torch fires and smoke plumes in Darkwoods. The solution is the same for any zone: delete the code or even the whole
_environmentemitters.txt file and the mysterious particles should disappear.
Here's a pic I took a couple months back when I was first figuring out this very feature. The particles are poorly documented, so I was testing various values in the char select zone when I accidentally lit the whole forest on fire. Whoops!
EDIT:
@Svielora, I see you're using ClickSwap's buff window but reverted to the default song window. I cobbled together a fixed version of the ClickSwap song window the other day that you can have if you like:
