When one rare dies, another spawns.
Check if Thome is up...
If he isn't up, loop through the other 19 rare spawn points, until you find which is up.
Rinse and repeat.
I only need Argyros on EI, but that rare spawns on the Invasion Superhighway that is Forlorn Fen.
It has a life expectancy best measured in seconds.
Not broken.... just a bit frustrating.
As far as the rest of the world rares, I need Aelfar Emissary, Dozer, Experimental War Golem, Mad Hogger, and The Predator.
Once in a while, I find myself hoping for Trion to have major technical issues, where they need to restart the server a few times while I'm actually home.
It is a bit amazing I've been playing over a year, since open beta, and I've *NEVER* seen any of these five.
It seems wrong to have to wait for outside human intervention to get a mob to spawn, but it is what it is.
