Federation TypesEdit

PHI reworks totally how federations work. Federations now revolve around ethics, and dishomogeneity is strongly punished.

All perks reported in the table below are already cumulated, and the president is not considered a member (so you can see what is got from every kind of member at every federation level).

Federation LawsEdit

Federation CentralizationEdit

Federation Centralization determines what Federation laws are available and is limited by the current federation level. Raising centralization will incur increasingly higher cost to cohesion and will gradually give back the diplo weight lost by members to the president. This reflects the federation getting represented in the Galactic Community by one voice, thus enabling a federation with many small members to have its president as a Galactic Council member.

Type President receives Every Member receives   Monthly cohesion Required level Description
Minimal 10% of every member diplo weight 0 1 The Federation's influence over its members is kept at a minimum.
Low 20% of every member diplo weight
  • +4% research speed
  • +2 stability
−1 2 The level of Federation influence over member states are kept very low.
Medium 30% of every member diplo weight
  • +6% research speed
  • +3 stability
−2 3 The Federation has a good deal of influence over its members, while still allowing some independent governing.
High 40% of every member diplo weight
  • +8% research speed
  • +4 stability
−3 4 The Federation's influence over its member states is almost absolute.
Very High 50% of every member diplo weight
  • +10% research speed
  • +5 stability
−4 5 The Federation has sovereign control over how member states are being governed.

Fleet ContributionEdit

The Fleet Contribution law determines how much   naval capacity is transferred from federation members to the federation fleet. The availability of laws is independent of the federation type, but requires high levels of centralization and cohesion.

Type   Monthly cohesion   Transferred naval capacity Max Fleet Size Required centralization Description
None 0 0 0 Minimal This federation has no collaborative military effort.
20% −1 20% 300 Low This federation has a minor collaborative military effort.
40% −2 40% 600 Medium This federation has a moderate collaborative military effort.
60% −3 60% 1200 High This federation has a extensive collaborative military effort.
80% −4 80% 1500 Very High This federation has a unified military force.

VassalsEdit

Vassals are never allowed into federations. PHI does this to prevent the exploit in which a vassalized federation member is not allowed to rebel to its overlord.

Successions, Vote weight, War declaration, etc...Edit

All other laws regarding the functioning of a federation don't require any centralization level to unlock. Any federation can be customized right from inception.

Federation CohesionEdit

The following incur immediate Cohesion   changes:

  • −50 whenever a member joins the Federation.
  • −100 whenever Federation Type changes

The following incur monthly Cohesion   changes:

  • +1 for each envoy assigned to the Federation
  • −1 for each member of the Federation
  • −0.5 multiplied by the number of different ethics, minus 2 (moderate and fanatic ethics of the same type will count as different ethics)
  • −4 for each opposed ethics

If a Federation loses the experience required for a level and fails to raise it above the required limit within 90 days, the Federation level will downgrade and remove all perks from the previously held level. Each level requires the following amount of experience:

Level 2 3 4 5
XP 600 1200 1800 2400

A Federation's experience is capped at 2400, meaning that at level 5 any negative Cohesion will downgrade the Federation level.
