Well known trick? I've hardly seen it used so I'd be curious what other wars have seen the tactic. So I could be better informed, if I am not.
The recent case, it was a already turn after the TO before it was bought. And it's *really* not a click race. If Pryde family *had* bought it immediately after TO, he probably would've failed (possibly arrested with option to banish). Military CS of the region owner is a big deterrence to region being bought, so Perdan moving out of the region was quite helpful to the recent incident succeeding.
So instead of jumping to new restrictions, lets explain the feature moreso. It would be great if someone recorded the information in the Wiki Manual.
To see the option to buy a region...
You're not on War Island.
You're not within your own realm.
Your family has more than 4200 gold.
You are not a rogue.
Your family has 1,000 more gold than the region cost.
-- The region cost is determined based upon loyalty to realm owner, population, and region type.
You are not travelling.
You have 4 or more hours.
Not live yet, but coming change will only display link when in region which can be bought (lordless, seriously wounded lord, imprisoned lord). Currently it displays for all and checks on the page itself.
To buy a region... (in addition to all of the above)
You cannot be a lord already.
You cannot buy regions from NPC realms like Netherworld.
You cannot buy capitals or regions bordering capitals.
You cannot buy rogue regions.
The more military CS of the region owner, the greater the chances of failure.
--Between the two 'now' and 'turn' options, turn is the easier one to succeed on, all else being equal.
Failure ranges from losing some gold, to losing more gold, to losing more gold (given to gov member of region owner realm as bonds) and being imprisoned with option of banishment. Those are roughly in order of least likely to most likely failure.
The turn option requires remaining within the region at turn change.
The turn option appears much more innocent and like an actual revolt than the now option.
If the region is already in the realm when the turn runs, there is recovery of some of the gold.
There are TODOs to add additional failure options to turn option when it runs the delayed buy.
Regions bought by estateless nobles join the nearest geographic duchy of the realm.
Regions bought by knights/dames, dukes/duchesses join their duchy. If a non-ducal ruler buys a region, a new duchy is created for his new region in the name of the new region (or if that already exists as a duchy name New RegionName).
I'm not adamantly opposed to a new restriction here, but I don't really see the necessity of it when its not used very often and has a number of additional restrictions already.
