Area, accessible to party of 8, with level 15 monsters?

Title. In any of the campaigns.

Why would I like to know this, you ask? I'm getting my Survivor-title somewhere in the extreme nearby future, but I thought... 'I'd just want the title to end on 1,337,500 exp! Otherwise it'd look stupid...', so, I decided that after I hit 1,337,400 exp or so, I'd start killing level 15 monsters with a full party of 8.

So, anyone? xD

Don't remember the name of it, but the outpost south of Champion's Dawn (could be way off on the name, but the one west of Kamadan). You can get a party of 8 there I think and in that area east of it I believe has level 15 creatures. (If that outpost only lets you have 6 people, try the one further east of it.

Issnur Isles, accessible from Beknur Harbor. Or Mehtani Keys, accessible from Kodlonu Hamlet. Or Lahtenda Bog, accessible from Blacktide Den. A few level 15 foes in Fahranur, the first city if I recall correctly (also accessible from Blacktide Den).

Ettins in North Kryta Province are also level 15. Probably lots more places as well.

ToA, has a party of 8 and the only place with party of 8 in Kryta.

Umbral Grotto leads you outside to level 15 Elder Crocodiles (pretty much where VS farm is)

I was going to say this^^ so instead I'll add my endorsement.

The 8 member party is probably done here and no where else in the area because this is where people hook up to go to FoW and UW. You can take advantage of this unique aspect of ToA and explore the surrounding areas easily with a full 8 member team. This is a great place for you. With you, 3 lvl 20 heros and the rest of your party in henchmen you'd really have to be a serious retard to die.

GL with your title.

I always think that Kryta has party of eight, then I actually get there and I'm surprised at the party of 6 restriction.

Raptor nestlings are level 15 outside Rata Sum.

If all you need is 100xp then just kill one enemy in Kilroys dungeon in NM they give 100xp each.

It must be a scream every time you go to the crystal desert then..

It's possible to get there with a party of 8, just difficult to do.

For some reason I still think party of six in the desert. My theory is that I spend more time out adventuring in the desert than I do in Kryta.

Or maybe I'm just insane, shouldn't discount that option.
I think the point was trying to fine tune the amount of experience. Solo killing a level 15 foe when you're level 20 will give 16 XP, but in a party of eight, that's 2 XP.
