"All icons are a multiple of 2 for a reason"
That still supports 2000×2000, since it's even. Why does nobody just say binary roots? Sounds cool and gets the point across right.
But yeah that darkness is odd, maybe they tjought the rune glow would spread farther.
The Havoc Stone icon in OG has a resolution of 2000x2000?????
For context, this is like, REALLY bad for optimization, and additionally ALL icons for this ENTIRE game are a multiple of 2 for various reasons.
The NORMAL resolution for marked icons (what this is) is 128x128
