Look up the skills of the President of a state. The development skills are global perks: each gives a speed bonus to every Chief in the state for a time. The other skills give the President gems or act on one Chief.

Use it to show what each skill does, what it costs in Authority, and how often it can be used. The positions the skills belong to are in Castle appointments.

State Search	chief	18,000	56	Locates the city of a Chief of the state
Supreme President's Will	state	n/s	n/s	Supreme President only

n/s means that the value is not stated.

The four development skills have a bonus and a cooldownSeconds of 7 days. The skills that act on a Chief have no bonus, because their effect is in the effect text. Supreme President's Will has supremePresidentOnly set to true, and it has no authorityCost, maxUses, or bonus.

Examples

import { presidentSkills } from 'whiteout-survival-data'

presidentSkills().count() // 9

const mobilize = presidentSkills().find('mobilize')!
mobilize.bonus?.value // '30%'
mobilize.bonus?.statKey // 'training-speed'
mobilize.bonus!.durationSeconds / 3600 // 24
mobilize.cooldownSeconds! / 86400 // 7
mobilize.authorityCost // 45000

// The global perks: the skills that act on the whole state

  .byTarget('state')
  .get()
  .map((skill) => skill.name)
// ['Medical Advancement', 'Mercantilism', 'Research Advancement', 'Mobilize', "Supreme President's Will"]

Known gaps

Assumptions

Medical Advancement shows a cooldown timer instead of the uses, so it has no maxUses. It has the same Authority cost as the other three development skills. The package gives the four development skills a cooldown of seven days.

The package states maxUses only. It does not say when the uses renew.

Receive Tribute lists three gem amounts, 300, 400, and 500, and does not say whether they are the amounts of the three uses. The effect keeps the wording of the game.

Authority is earned by the President. The game says: "Whenever Chiefs within the State claim Daily Mission Chests or gather resources, the President gains [Authority]. President Skills expend [Authority]." The amount a Chief earns is not stated.

The skill icons are small, about 60 by 60 pixels, and the Ceasefire, Forced Exile, and State Search icons are about 98 by 98. Supreme President's Will has no img.
