Open the character you want to kidnap
Check if they can be abducted through a hostile scheme
Start a Scheme against them and choose Abduct if available
Assign the best Spymaster to the scheme
Use Bribe on the target’s courtiers, guards, or powerful vassals to increase scheme success
Bribe anyone with high Intrigue or access to the target
Bribe the target’s court members to lower secrecy and increase scheme progress
Use hooks to force agents to join the scheme instead of bribing them
Keep your own Intrigue high to improve scheme power
Use perks from the Intrigue lifestyle, especially those that boost hostile schemes
Increase scheme secrecy by bribing or silencing likely informants
Wait until the scheme reaches high success before triggering the kidnapping
If the target is in a court with many bribable members, keep bribing until the scheme becomes viable
Use gold to maintain bribes and keep agents loyal until the scheme fires
