The Initially-not Spawned Monsters In Abyssea

Did we ever figure out what the conditions are to make certain monsters appear that weren't initially present when the abyssea areas were opened?

none of these monsters are spawned on the test server and I was looking for certain ones to test stuff on.

I also wanted to fight the Ironclad Executioner, but I can stand on and walk over his pile of parts and he doesn't assemble or aggro.

I think it was thought to be based on the amount of mobs killed. I got out of the loop around the time of the second expansion, so I might have missed something.

Might want to post about this on the official forums and get the devs' attention. Seems like they would want everything available to you for testing purposes.

I just did. :p

I take it though, that no one really knows how this crap works (which is understandable, because once they've been spawned, they don't go away)

I think they're more interested in having us test upcoming content than existing mechanics, sadly. Would also have loved to get a chance to test various mythics since there's so little information on them.

The idea here is to test job adjustments, which are part of the test server update. I can't do that if I don't have the full range of monsters normally available on the live servers to test on.
