Area To Grind Lv100 Mobs?

So I've got the "Slay 110 level 100+ mobs" objective and I've searched through sky islands and can't find any spot that has a good source of lv100 mobs, or at least a spot that wont take a huge amount of waiting to kill 110 of them.

What I've found:
Dragonling Cave has one dragonling that is lv100, but it isn't a super common spawn like the black dragonlings in there are (it's the white one that's lv100)
Some cave kinda near Jofash has the Man in the Mirror which is also lv100, but he isn't that common of a spawn either, and it seems it'll only spawn one at a time.

I've been suggested to just go through LI and grind mobs on the Yahya stage but I don't really want to drop the EB on a ticket when I'll likely not even make the money back from the rewards from the objective, so I don't think that's entirely worth it.

Any spots?

 

If you go down to the Void and head south to the very farthest island, there are a bunch of level 105 mobs.

Unless they changed the level of those mobs for this objective, in which case, fuck you too GMs.

I understand that you already have an answer in ToA/Hive. But, there's "Dragonling Nest" in Sky Island that has a Lvl 100 Dragonling Mother and after it is killed will respawn in 3 seconds.

 

Also the eggs/minions that spawn are lvl 100. takes a couple of minutes to finish the quest.

 

this is not necessary ^_^
