So if you want to raise provocation this is the place to do it. Moonglow Zoo in Trammel. The spawn in this cage has been increased and Arctic Ogre Lords have been added in. You can go all the way to GM here after you get your vendor training.
I even have a really great UOSteam Macro for you to use if I can get it to post right. Just copy and paste below into a new macro in Steam and you're good to go!
BTW you can also get a good amount of tokens and gold doing this!!!
