I started Provo at 50 and was 110 provo in one night of watching T.V.
How you ask? Exodus Overseers near Honor Shrine in Ilsh.
Goto Honor, head north in the cave, you'll see enslaved gargoyals.
Grab 2 of the overseers, drag them east past the savage camp, and north to the garden area north of the ridgeback spawn area. (You'll see what I'm talking about if you head north) There will be a small platform you can teleport onto in the middle of the lake with a garg statue on the top.
Since the overseers are non magical, and imune to physical damage, they will never kill eachother.
You can safely provoke all night long and never have to worry about a death^^
If you can seem to find the spot, ask me in game, i'll be happy to show you where its at.
