1.23 Imperial Event

[Altena]

My Theory- This "event" that was unannounced on lodestone was simply a 4hr "stress test" for the upcoming patch. For all we know, it won't show up again til the update coming tomorrow.

I believe it doesn't have a "random" or "set time" as such, but simply a button that SE switches to the "ON" location for a 4hr period. I daresay they are planning something quite large scale for the final patch, and this little "event" is simply to make sure the servers don't die in the fiery pit of hell.

As for drop rates, it is random/participation. I don't believe killshot or claim has much to do with it. There are too many conflicting theories behind it.
