Hmmm, where to begin…
IMC I limited Lts. performing Domain Actions in place of the regent to once per season. There’s some solid reasoning behind this (besides it being the rule in 2e as I understand things): only an invested Regent really has the power to utilize the full resources of his domain. There’s also a very important game balancing factor here too: a single Lt. is prevented from running a realm entirely on a regent’s behalf. IMO a Lt. should reflect a limited version of the regent, one who can act in the regent’s behalf but not for 3 domain turns per season.
I think there should be a very solid distinction between Lts. and Advisors: Lieutenants are invested with a Ceremony Domain Action; this is in part a mystic ritual, because it imbues a Lt. with the power to act in the regent’s name, which means they have the ability to spend both GB and RP when performing a domain action. Moreover, I believe that it should be ONLY an invested Lt. who can perform a standard Domain Action in the regent’s behalf, using their Character Action and any applicable synergy bonuses from a relevant skill; Advisors should be limited to Court Actions, not having the invested authority to act with the full power of the regent himself.
So, this leads to several reasons to have invested Lieutenants: their skills may compliment their regent’s, making them better suited to certain domain actions than the regent himself. Don E, this should answer your question about why one would bother with Lts. at all. A Spymaster, for instance, could serve an invaluable role performing Espionage actions for his warrior liege. A Fighter regent could use his Chamberlain, a Master Administrator, to Rule a province, while he uses his character action to adventure or train a unit (a Court Action where his Lead skill is important) or just take a break from rulership, perhaps spending time with family or friends (everybody needs a vacation once in a while, even PC’s
). If a regent wants to be off adventuring for months at a time, he should then have 3 or more invested Lts. if he wants to fully utilize his domain actions without personally overseeing them. Failing this, his court can direct the actions, but there will be no skill synergy bonuses from an invested character directing the action as there would with a Lt. or the regent running it. RP and GB can be spent normally here, at least using the current BRCS rules.
By contrast, an Advisor is to me nothing more than a glorified courtier, a member of the regent’s court singled out for their exceptional abilities in one or more areas, and probably given extra pay/lands (1 or more GB/season) to reflect this. However, as only a Decree Court Action would be necessary to name an advisor, I don’t think they should be invested with the same sort of power as a Lt., meaning they cannot perform Domain Actions in the regent’s name. Again, only the regent or an invested Lt. would have the necessary authority to coordinate such an action effectively.
Now, as to why would you want an advisor to run Court Actions? Well, by the BRCS rules, there are several areas where such a character would be extremely useful: leading and training units in the regent’s or allies’ realms, for one thing. It only requires a Domain Action to wage war in neutral or hostile territory. A defensive war requires only Court Actions, or none at all in the regent’s own realm; thus, a marshall [advisor] could lead defensive forces, a vital role if the regent happens to be off adventuring, or perhaps waging war elsewhere when the home realm is attacked. However, having a commander capable of leading an offensive campaign (a War domain action) should definitely require an invested Lt. as opposed to an advisor IMO.
Training units with the Lead skill also requires a Court Action and the Lead skill. This is a role where militant advisors have been invaluable IMC. Champions of a realm are often appointed with advsor status IMC to do this, and to act as heroic unit commanders (Hero Units) - well worth a few GB per season if and when war breaks out.
Finally, I use Court Actions to cover all sorts of more minor actions that wouldn’t require the main focus of the realm’s court and resources. Examples include recruiting other courtiers within the realm or in allied realms, something which I would allow Lead or Diplomacy synergy bonuses to affect; Diplomacy actions to allied nations to work out details of some specific arrangement might only require a Court Action, since a standing alliance already covers the major groundwork required of a full domain Diplomacy action; a Master Engineer is another advisor-type who can maximize Build CA’s (Court Actions); and finally, character-led Diplomacy and Espionage actions where a regent has Embassies and Spy Networks respectively are only Court Actions, but these will benefit from a Lt.‘s or Advisor’s synergy bonuses. The last are also examples where a regent’s RP and GB could make a big difference backing up a Lt. or Advisor despite them being only Court Actions, but the characters’ synergy bonuses can save the regent some resources by providing a bonus from the beginning.
