Überdiplomat - what to do with him

[ReiseReise]

I recruit a diplomat, and wow he has 6 skill. I send him on a 1 turn mission from Venice to Bologna to buy the later and he gains +3 skill:


So now I have a 9 skill diplomat I don't want to let this guys skill go to waste, but I don't use diplomats very much except for basic trade rights/map exchanges so I am not sure how to use him effectively.

Does skill affect negotiations or is it only for bribery?

Any ideas on what I should do with him?

I am Byzantine E. and have expanded west to Venice/Bolonga and east to Antioch. Venice is dead, Turks are dead (Family died in battle in Anatolia so eastern Turkish provinces are rebel). I am not at war with anyone for the moment. Holy land and everything east is rebels. Crusaders are annoying me marching through Anatolia.

Tell me your cunning and evil plans, muahahahahaha.
