I was thinking, that its kinda silly that the only way to 'take over'
somebodys land is to contest his holding down to nothing or invade his
land with an army..

I came up with this domain action. Im not sure if ill use it, but
please-- PLEASE give me opinions :)

'Contested Rule' Success: 10+
Type: Domain Base Cost: 2gb,
variable RP

With this action, the regent spends time and energy advancing the causes
of one of his holdings-- at the expense of someone elses holdings. By
using the contested rule, he increases his share of the pie while
denying his opponent access to said pie.

Note: You must have a zero level holding in the province to use the
contested rule action and there must be room for two seperate holdings
(ie. the province has to be over third level, provided that the DM
uses that rule.. If not, he can use this at any time)

Ruling a holding in this way costs 2 Gold Bars plus Regency points
equal to the desired level /and/ the level of the target holding. For
example, if your ruling your 0 level guild in a province with a guild 4
you would need to spend 2 Gold Bars plus 5 regency points.

You cannot use this as a realm action, you can only use Contested Rule
on one holding at a time.
