Here is a simple guide for training Provoking.

What is required:

GM Musicianship
Provocation
Instrument

First train provocation off a bard. You can find bards in Britain near the blacksmith. This will require gold. I use the following skill table as an example for training provocation:

Provocation:
0 - 25 Train off a Bard
25 - 50 Provoke Two Polar Bears
50 - 94 Provoke Two Giant Beetles
94 - GM Provoke Two Ogre Lords or Rotting Corpses

Go tame two polar bears, or if you don't have a tamer, go buy two polar bears. Ask around Britain and Delucia if anybody is selling polar bears or can tame two polar bears. I use polar bears because they are easily tamable and can be found on Ice Isle near the Honesty shrine.

Go to a carpenter and buy at least 8 tables. Find a safe spot, or if you have a house, lock down the tables and block in the polar bears, but make sure the polar bears can't melee each other and are within provocation distance. After you have locked in the polar bears using the tables release them so that they are wild. Now make a simple macro to use provocation and target both polar bears.

After you have macroed to 50 provocation switch to giant beetles. Only this time you will need to stable one giant beetle at a time. Use the same method for provoking giant beetles as you used for polar bears. It is important the beetles can't melee each other, unless you are also training veterinary, in which case you won't need tables.

After you have macroed on two giant beetles until 94 provocation, you will need to find either two Ogre Lords or Rotting Corpses to GM provocation. I chose Ogre Lords and Rotting Corpses because they are easily provoked at that skill level and don't cast spells.
