Power projection is a mechanic which rewards nations for acting aggressively towards their Rivals and demonstrating their strength. It encourages nations to have long-lasting feuds and to work against worthy adversaries. Aggressive acts include embargoing, declaring war, taking provinces, subsidizing enemies of rivals, and sending privateers. Its value is capped at +100.
Power projection is gained through static effects that last until cancelled and event modifiers which decay over time. All event modifiers decay at a rate of −1/+1 power projection per year and are counted for each rival separately (Insulting a rival is the only notable exception here). Event modifiers do stack, but are capped at a maximum value. Everything exceeding this value is lost.
Example: 23 power projection is left from eclipsing rivals. Eclipsing another one would add another 10 power projection, potentially resulting in 23 + 10 = 33 power projection. However the value is capped at 30, so 3 power projection is lost and the value is set to 30, decaying at the normal rate of −1 power projection per year.
|Long-time rivals||+1/year||+5 per rival|
|Embargoing a rival||Up to +10 depending on the embargo's impact on the rival's trade|
|Subsidizing a rival's war opponent||+0.5 per percent of total income given, while the war lasts|
|Privateering in a trade node where a rival has trade power||Up to +10 depending on impact on the rival's trade|
|Great power||+10 to +25 according to rank|
|Completed age objective||+3 per objective|
|Declaring a war against a rival||+10||+20|
|Honouring call to arms with a rival as war leader||+10||+20|
|Taking provinces from a rival or giving them to a vassal in peace||+0.5 per development||+100|
|Signing a peace in which a rival loses provinces||+0.5 per development||+100|
|Vassalizing a rival||+0.5 per development||+10|
|Insulting a rival while not in a truce||+5||+5|
|Scornfully insulting a rival while not in a truce||+10||+10|
|Eclipsing a rival||+10||+30|
|Supporting rebels in a rival||+50, modified by the percentage of income used by the supporter||50|
|Empty rival slot||−1 per year[Note 1]||−20 per empty slot[Note 1]|
|Dishonouring a call to arms against a rival||−20||−20|
|Losing provinces to a rival||−0.5 per development||−100|
|Being humiliated/shown strength||−30||−30|
- If there are fewer than three eligible countries that are not allies, the extra empty slots don't contribute to the penalty.
If a rival is replaced, completely conquered or ceases to be an eligible rival, all static effects gained against that rival will be lost; except for replacement, the loss power projection is generally compensated by the other factors that apply (conquest, losing provinces, vassalizing, and eclipsing). Power projection resulting from event modifiers is not lost, and continues to decay normally.
Having positive power projection provides several scaling bonuses. There is no penalty for having negative power projection; it cannot go lower than 0. For each point, the following bonuses are given:
|+0.2%||Global trade power|
|+0.1%||Morale of armies|
|+0.1%||Morale of navies|
|+0.002||Yearly republican tradition|
|+0.005||Yearly horde unity|
Having at least 25 power projection gives:
|+1||Leader(s) without upkeep|
Having at least 50 power projection gives:
|+1, +1 and +1 monthly|
