Like many aspects which can be
contended among players, the Curia controller has been bestowed with rewarding effects —
larger than in vanilla. Holding supremacy over the college of cardinals now provides:
These bonuses will be lost when Catholicism becomes a minority religion in Europe. This is to avoid situations where the only Catholic player left is able to milk his lonely religious position to great advantages.
It is harder to gain magistrates in "Omnium Contra Omnes" than in vanilla; the one player exercising power over the Papacy will count on a tangible advantage in that domain. Diplomats are also scarcer and actually limit the extent of diplomatic initiatives. Unquestionably the most extensive advantage though is the one granting +1 tolerance, which decreases revolt risk, although exclusively in Catholic provinces.
In the unmodded game there are few advantages to remaining Catholic once other Christian branches become available: the economic incentives of reformed religions invite most players to convert. It is now more enticing for a large colonial nation to retain the possibility to gain additional magistrates.
Papal Influence:
To ascertain power over the Curia one can manipulate two factors:
a) number of Catholic provinces owned and
b) Papal influence. There's no need to elaborate on the first (conversion, military conquest) but let's consider the second.
Papal influence used to be gained almost
exclusively by maintaining positive relations with the Papal States: anybody who didn't do so risked to be excommunicated with few chances to regain control in the short time. It's quite easy to send out a few inexpensive gifts to a minute Papal State. The roles of narrow-mindedness, missionaries and crusades have been emphasized at the detriment of diplomatic relations with the Papal States. The latter still provide +10% yearly influence when relations are maxed, but it is offset by a base -5% Papal influence for all Catholics; furthermore selected events lowering papal influence in certain circumstances were introduced.
These are items affecting yearly Papal influence:
Among these, "Holy See Affinity" is new: it is a triggered modifier rewarding those countries sharing the same cultural group as the Pope. At the onset of the grand campaign, that's Italian nations — but it's subject to changes if one were able to annex the Papacy or support an Anti-Pope.
"Credit Instruments" and "Bank of St. George" are financial decisions lowering interest rates, their main detraction is reduced influence on the Curia: money lending was abhorred by the Catholic dogma. These decisions shall be discussed in their own section.
Please note that "Ecumenism" and "Humanist Tolerance" do not decrease Papal influence anymore, although they determine it indirectly. The "
De Heretico Comburendo" decision is available to those who wish to pursue a pious career: it will decrease heretic tolerance by one but increase Papal influence by 5% yearly. Since there
aren't Christian heretics in 1400, the decision will actually promote the rise of heretic rebels like the Lollards or the Hussites, via a possibly dangerous event. The decision can then be cleared by either converting or adopting "Ecumenism".
There also are specific actions increasing and decreasing Papal influence, these are:
Conversions, from any religion to Catholic, provide +9 Papal influence, that is three times as much as "delegates".
Cardinals
Papal influence increases chances to sponsor cardinals in the Curia. In the "Omnium Contra Omnes" cardinals attend to their function five years longer than in vanilla, on average. This change derives from the want to avoid yearly fluctuations in who becomes "Papal Controller" and which actions they enact or repeal. There remains an element of luck in acquiring cardinals, but effects last longer — so that they can be planned on.
Each cardinal grants his sponsor these effects:
The change, from vanilla, pertains to stability investments: it's five times higher in the mod and matches the mod's increased stability costs. Catholic countries will tend to have lower stability costs than their Protestant or Reformed counterparts, due to their lower base stability costs, due to cardinals and an early available "Suffragan Bishop Act". Orthodox countries though best Catholic ones, in this regard. Please note that, in the mod, acquiring
one cardinal can equal to 800 ducats invested in stability, on average, over the cardinal's lifespan, that is fourteen years — an
immense help to medium or small sized countries and a motivating factor in choosing "narrow-mindedness" over "innovativeness".
The "Frame Cardinal" espionage mission allows one to decrease the target's Papal influence, and therefore his chances at gaining cardinals in the Curia. Its chief requirement is that the target features a cardinal among the Curia and the province features a temple.
Fading Catholicism
There may be times when most players convert to Protestantism or Reformation leaving one or two players to contend the "Curia Control". In those, arguably rare, cases — the last two Catholic country, or countries, will benefit from a
watered down "Curia Control" advantage. The principle being that
the fewer Catholic provinces exist in Europe, beyond the Papal Controller's frontiers, the more likely he is to lose the full benefit of the "Curia Control".
In practice, a "Fading Catholicims" triggered modifier will fire when:
The effects tackle the "Curia Controller" most significant advantages and therefore remove:
