Hahaha
Well, I tried quite a few setups. Medium skilled all round, few high skilled ones...major problem is you're severely limited on your equipment that you can bring...only axes really...all my attempts failed as party after party got slaughtered. They did rather easily manage to kill 2 forgotten beasts, but that diplomat is something special.
Gave up in the end and with severe regret loaded an old save before the diplomat showed up. Two seasons later guess who comes a-knocking ? It's that damn diplomat again.
This time I was a bit better prepared, unfortunately the defenses for my waterpower plant were not finished and they got all trashed (so much work lost ! FUN !)
With everyone locked in the mountain and all walled up I lost track of the diplomat.
Turns out he is hiding underwater 7/7 (WTF dude
).
He doesn't seem inclined to get back out so I reopen the fortress for business and start work on finishing the waterpower plant defenses.
Of course eventually the sod manages to sneak back into my fortess after spending 30 min underwater.
OH NOES !
He does not actively attack dwarves, that's the wierd stuff. He begins to randomly destroy some stuff and spends some time sulking now and then.
After several failed attempts I manage to wall him in. Then I proceed to stage a cavein on top of him. He manages to survive the cavein (not sure if he's so awesome or if he escaped) and once again is loose in my fortress.
Well, nothing for it. Once more I rally the troops but seeing as he does not attack first I take my time getting everyone to get their bronze axes and spears out and their leather armor on. When I think my gang of hoodlums is armed as well as possible all 30 attack at once. In seconds I see dwarves fly across the roam to be splattered against the walls but after he killed 3 and maimed another 3 one of my dwarves gets a lucky axe swing in and his head flies around the room.
It's 04:00 AM and I gotta work tomorrow and I'm so happy I might cry
