Players can start murder plots by selecting "Plot to Kill" in the target's diplomacy menu, or by clicking the "Choose a Plot" button to the bottom left of the target's portrait.
You can get a list showing who would accept, and who would accept with a bribe, among the target's courtiers and vassals. The "auto-invite" checkbox quietly invites everyone from this list.
If the target is a vassal, their fellow vassals and their liege are also valid conspirators. You must invite these rulers manually.(?) The fastest way to do this is to go to their liege's character view, select the vassal tab, and right-click each vassal (including barons).
Characters are more likely to accept an invitation to a plot if they like the plotter, dislike the target, and have traits such as deceitful that reduce ai_honor. When targeting a child who is not a ruler(?), the diplomacy skill of the primary parent(?) is checked instead of the child's.
The plotter and conspirators contribute plot power. Each character's plot power contribution depends on their intrigue skill and position. When targeting a ruler, council members have double plot power. When targeting a child, the guardian and regent have additional plot power.
Your plot becomes more likely to fire:
- When you reach certain plot power thresholds:
- Minimum 50% for conspirators to attempt
- 3x at 100%
- 3x at 150%
- 3x at 200%
- Roughly linearly:
- Unless you are at the target's location, it's only linear with the total contribution from conspirators
- The exact speedup depends on the individual plot power contributions
For example, suppose you have 110% plot power, with 50% personal contribution and 60% from conspirators. Adding a second set of identical conspirators would show a total of 170% plot power. But the actual effect would be to double the number of event targets (2x) and get you to past one more 3x threshold, for a total of a 6x speedup.
Carrying out the plot yourself only requires being at the target's location. This event does not require 50% minimum total plot power, but otherwise benefits from total plot power in the same ways (3x boosts at each threshold).
The conspirator who sets the attempt in motion must pay to do so, unless plot power is 100% or they have a specific skill of level 10.
The chance of success is dependent on the plan used and the target's traits. For example, attempting to assassinate someone with poisoned wine is half as likely to succeed if the target is Temperate . Paranoid characters are more likely to survive in most plans, while Trusting characters are significantly more likely to be killed in most plans. Every time an attempt is made, whether it succeeds or fails, there is a chance the conspirators will be identified.

murder_in_motion flag can get stuck, preventing their conspirators from initiating murder plans. If you have 200% plot power and the plot hasn't fired for over 2 years, this is probably why. Check with
charinfo console command, and fix by restarting the plot or editing the save.
- Increase your state diplomacy and state intrigue
- Focus on crossing total plot power thresholds (50%, 100%, 150%, or 200%)
- Remove the target's spymaster, especially if the likely replacements are pliable or incompetent
- Be at the target's location by leading troops (stay safe by checking the revolt risk map mode)
- Seduce possible conspirators, if safe and nearby
- Target new rulers, who have a short reign penalty and won't bother to fire a spymaster who hates them, before factions fire
- Target parents first if you want to kill a child
Marry courtiers into the target's court who have high intrigue and are likely to join the plot. Characters are more willing to join assassination plots if they like you, dislike the target, and have low ai_honor. So try to send characters who are:
- Different culture group (-10 opinion)
- Envious (-15 opinion of liege, -10 honor)
- Deceitful (-25 honor)
- Greedy (increased bribe effect, -10 honor)
- Opposite traits to target
- Ambition is not obj_get_married (+10 opinion of new liege for 2 years)
Remember that you can't send highborn characters off to marry lowborns. Avoid sending spouses to close relatives of the target, as they will get +15 opinion (marriage ties).
You may be able to invite women for free if you have high diplomacy and seduction focus.
It is especially useful if you can place a new spymaster. AI rulers are reluctant to appoint spymasters with strongly negative opinion, so focus on low ai_honor rather than low opinion.
Discovery of the plot
The chance of a plot being discovered is dependent on the target's intrigue, or state intrigue if the target is a ruler. As with other plots, there is a chance of it being leaked by its backers. It is also possible for a character to become suspicious of an assassination plot without knowing who its backers are. Characters who are Paranoid are ten times more likely to get a whiff of plots against them, their spouses and their children. Any plot backer having an Intrigue lower than 3 or being an Imbecile , Slow , a Drunkard , or a Lunatic makes this happen quicker.
As with any plot, when an assassination plot is discovered, anyone involved can be asked to stop backing it as a diplomatic action. The head of the plot can be imprisoned without incurring tyranny. Imprisoning the head of the plot will end it. Plot backers can be righteously imprisoned if they are asked to end the plot and refuse.
Discovery of assassination attempts
You are implicated if you are the plot leader or the plotter who set the plot in motion. You get the "Dishonorable" opinion modifier with your religious head and everyone in the realm of your target, a -10 penalty that stacks with multiple instances of being revealed, lasts for five years and allows righteous imprisonment by your liege. The target's parents and children will have a -50 opinion penalty while siblings will have a -25 penalty. Additionally, the target of the plot will get a stacking "Attempted Murder" opinion modifier towards your character (-200).
There are additional penalties for a discovered successful murder attempt. You will receive the Known Murderer modifier, a permanent -10 opinion penalty with everyone. If the character was in your dynasty, you will become a Kinslayer (-3 diplomacy, -25 dynasty opinion). The murdered character's close kin will be especially angry (-30). Their parents and children will additionally consider you a rival (-100 opinion and may try to murder you).
Going into hiding
Characters may go into hiding if they are aware of a plot on their life, even if they do not know who the plotter is. Rulers can also send unlanded spouses or children into hiding if they are targeted.
Going into hiding cancels an in-motion murder attempt if there is one. Plans possible against a target in hiding require 100% plot power, trigger less frequently, and are far less likely to succeed (base 18% chance of killing the target, 27% with extra investment). If they fail, there is a high chance of discovery.
However, a character who is in hiding is subjected to reduced Diplomacy, lowered vassal opinion, monthly Prestige loss, and events that inflict negative traits. A character who spends time in hiding can become a Lunatic , Celibate , Depressed , Ill , Pneumonic , Gluttonous , Slothful , Shy , Craven , Content , Possessed , or a Drunkard . It is also possible to gain Paranoid , Zealous , Hedonist , Scholar , Mystic , and Poet .
