Diplomatic mission success rate?

[Falesz]

Hey all,
Does anyone know how the succes and failure chances are calculated for a diplomatic mission? Is it the diplomats gravitas, ambition, public office, age? Does it matter which political party my diplomat is from? Any of their traits matter? Does it matter what sort of positive or negative terms I'm on with the target faction?
Any help would be appreciated. To me it seems like the result completely random.

I've only tried it a few times with guys outside my political party. They failed everytime. I'm not sure if guys outside your party fail on purpose to be a ♥♥♥♥. I should probably try it with my own guys to see if that makes a differnce.

In my current campaign got ahold of the whole of mauretania through diplomatic missions. My diplomat is a woman from my party with 700+ gravitas but I also got scytgian territory as a gift when she had 400 gravitas

They don't do it based on political affiliation (at least not entirely). Your own heir to the ruling seat will betray you and diplomats from other parties will still score you a settlement with a critical success based on some success/fail rate.

I'm interested in how this is calculated. What factors weigh in into this calculation? I don't know how to access the game's code, nor do I reckon I would understand much of it so if someone knows their way around the data tables and stuff in the game files, I'd appreciate the help.

The diplomatic mission political action outcome is calculated (with a hint of randomness) like the agent actions. The factors affecting the percentage chance of success are:

• Politician's Ambition (the higher it is, the more chance of success)
• Politician's Gravitas (the higher it is, the more chance of success)
• Faction's Relationship (the higher it is with the targeted faction, the more chance of success)
• Faction's Settlements (the more settlements the targeted faction has, the more chance of critical success. If they have no free settlements to give, you will never get this outcome from that targeted faction)

With these factors taken into account and a bit of RNG, you will get these outcomes:
• Critical Failure ("Execution")
• Failure ("Wounded" or a random debuff (e.g. decreased technology research rate, decreased movement speed). Politician acquires 5 gravitas)
• Success ("Tribute" or a random buff (e.g. increased technology research rate, increased movement speed etc). Politician acquires 10 gravitas)
• Critical Success ("Settlement Gift". Politician acquires 20 gravitas)

Thank you for your help.
Well this new feature has been rather disappointing so far. Even though through the course of my campaign I gained control of entire provinces thanks to it, just now in 3 consecutive turns I sent out 4 diplomats. In all 3 turns, 1 of them succeeded and 3 of them failed.

All the effects of diplomatic missions are listed on the faction overview panel, above your Imperium meter. There you can check how many turns they will be ongoing for. Generally it's 4 turns, I think.

The gifting of faction's settlements is simply stupid and broken idea. Even more stupid is that you can not refuse it, or gift it back to previous owner or anybody else. Can't use diplomacy anymore, because i'm afraid that AI gifts me cities I don't want. Yes, of course Rome would give me a city in the middle of Italy and next to freakin' ROME, but still refuse to trade with me. Still hoping that somebody makes a mod which disables the gifting completely.

[Falesz]

Yes it is indeed stupid, and not very good for any kind of roleplay, since the options are very limited.

But at the end of the day, I just don't care anymore. The more random settlements they give me, the sooner I'll hold 80 settlements for the military victory of most factions.

Super idiotic RNG mechanic. It just fails all the time resulting in the complete opposite: negative diplomacy, for which you paid money. Dont know why the devs of this game love braindead RNG so much.

And then when a mission turns out to finally be successful you can be gifted an entire province in some of the successful missions?! what the hell is this nonsense.

" With these factors taken into account and a bit of RNG,"

your this sentence makes all other previos sentences invalid as well. It is simply stupid RNG terribly poorly implemented to the game and very very frustrating.

I just ignore that unreliable mission entirely and focus on the games and food missions instead to level up my females, getting OP, food and loyalty.
