Can confirm these are real. A fellow player showed me 2x q10 and 1x q12 that they have managed to get so far. They too are trying to keep it a secret till they become common weapons
If that's the case, then it doesn't have a different drop rate. Its just very specific to a certain area, where it Drops. Once found out, this will be like the hourglass. Not sure why anet would do this only with the Glacial Blade, but maybe there is more into this.
Well for the drop rate part I’m not sure, as a good example of the years I’ve only ever had one gold OS spiked club after well over 1000 hours of target farming for them yet others have had multiple. Same goes for magmas shields though which I have dropped 30-40 dual mods yet others have had 1-5.
I believe your correct though once it’s common knowledge it will become a 200a item then 100a and keep halving rather quickly from there
But for now grats to those who have figured it out and are playing the market by keeping it a secret
although I can think of a staff that could replace that center piece
