But you need to go back and read the section on Resolving Actions to find out “what is normal”. These rules apply all the time, unless specifically called out as otherwise. The normal rules for general and specific text would apply to the BRCS.
Regents with the same type of holding may apply the holding level as a bonus (support) or a penalty (oppose) to the check. In addition Law holding may be applied to Temple and Guild holding actions in the same manner.
All regents with holdings and the province ruler may also use RP to influence the action (add as a bonus - support, provide as a penalty - oppose).

Create Holding [Standard; Administrate; 1 GB][/b]
A regent wishing to establish a holding in a province where he has no holdings of a specific type may attempt to create a holding (0). Once created, the regent is free to Rule the holding to a higher level (if the province level permits such growth) or to contest existing holdings in order to increase the influence of his holdings.
The base DC for the domain action check is 10. As usual for standard domain actions, holdings of the same type as you are attempting to create may apply their level as a bonus or penalty to the action check. In addition, however, law holdings may apply their levels as a bonus or penalty to the action check if the target holding is a guild or temple. As usual, all regents with a presence in the province may bid RP to support or oppose the check.

Resolving actions[/b]
Domain actions, like many combat actions, are not automatically successful. Many require a domain action check. A domain action check is the roll of 1d20 plus any modifiers. The base Difficulty Class of a domain check is dependent on the specific action attempted. The following modifiers commonly apply to success rolls for domain actions:
Holding modifiers: +1 per level of allied holdings of the selected type in province, -1 per level of opposed holdings of the selected type. The regent or members of his court carry out the administration of a domain action, but for most domain actions, the details of the action are handled by the employees and personnel of a holding under the regent’s control. When you take a domain action in a province, you must use one of your holdings in the province to execute the action. You gain a bonus to the action check equal to the level of this active holding.
In addition, other holdings of the same type as your active holding can support or oppose your action. Using holdings to oppose or support another regent’s actions is not a domain action. Allied holdings of the same type provide a bonus equal to their level. Opposed holdings of the same type provide a penalty equal to their level. Holdings of different types cannot add or subtract their level to your check. Any applicable regent may order such support or opposition once he is aware of the action. Support from holding level is highly visible, all regents (and residents) of the area will be aware of the regent’s support, opposition, or apathy regarding the action.
Skill modifier: (Full domain actions only) +1 for every 5 ranks that the regent has in the relevant skill. Each domain action is dependent on a specific skill listed in its description. If the regent sacrifices his character action to take a personal hand in the implementation of the domain action, then the domain action receives a bonus proportionate to the regent’s skill.
Loyalty modifier: +1 for Helpful, -2 for Unfriendly, -4 for Hostile. The attitude of a province’s population toward the active regent has a significant impact on any actions that he takes in the province.
Regency Points: +1 per RP spent to support, -1 per RP spent to oppose. Regents may spend RP to support or oppose most domain action checks. The province regent and any regent that has any holding of any level in the province in which the domain action is taking place may spend RP to support or oppose the action. There is no limit (save availability) to how many RP may be spent to support or oppose an action.
Spending RP to support or oppose an action is done in reverse domain initiative order. Each eligible regent may spend RP to support or oppose the domain action check. Each regent must be offered the opportunity to spend regency each round. Bidding continues round by round, until a round passes in which no regent bids additional RP, a which point the domain action check can be made.
Although it is obvious when a holding level opposes or supports an action, the spending of RP is not necessarily so. RP can be spent “anonymously” at the regent’s desire. The player is always aware of the RP being spent against them (and can use this information during bidding), but the character may not be aware of the mastermind behind the forces opposing his action.
