Terra Invicta Councilor Guide — Recruitment, Missions & Leveling Strategy
Councilors are the face of your faction on Earth. Every nation flip, technology breakthrough, and covert operation is executed by a councilor somewhere on the globe. Understanding how to recruit the right councilors, assign them to the right missions, level them efficiently, and protect them from enemy operations is the difference between controlling the Earth and watching it fall to the aliens or a rival faction. This guide covers all six councilor professions, the six core stats, mission mechanics, leveling strategy, organization management, and transfer rules.

Councilor Professions — Stats and Best Use
Every councilor belongs to one of six professions: Politician, Scientist, Spy, Operative, Celebrity, or Officer. The profession determines which stat is the primary stat (gains +2 per level-up) and which missions the councilor is naturally suited for. A Scientist with 8 Science will complete Advance Research missions faster than a Politician with 8 Persuasion attempting the same mission. That said, any councilor can attempt any mission if their relevant stat is high enough; profession determines aptitude, not permission.
In the early game, Politicians are king. Earth control determines your resource income, research speed, and military capacity. A single high-level Politician can control 3-4 G20 nations simultaneously through the Control Nation mission. As the alien threat becomes military rather than political, Officers and Operatives become more important. Scientists are always important but their impact is delayed; they do not help you until the research project completes. Plan your councilor recruitment to match your strategic phase: Politicians first, Scientists second, Officers and Operatives third.
| Profession | Primary Stat | Secondary Stat | Best Missions | Best Use |
|---|---|---|---|---|
| Politician | Persuasion | Administration | Control Nation, Public Campaign, Sway Nation, Boost Ideology | Dominating Earth control. Politicians are the most important profession for the first 15 years of the game. A level 10 Politician with 8 Persuasion can flip a G20 nation in a single mission cycle. |
| Scientist | Science | Administration | Advance Research, Steal Technology, Boost Research | Accelerating your tech tree. One high-level Scientist reduces research time by months. Essential for reaching fusion and antimatter before the aliens. Place Scientists in factions with strong research infrastructure. |
| Spy | Espionage | Investigation | Infiltrate Faction, Sabotage, Gather Intelligence, Crackdown (on enemy councils) | Destabilizing rival factions. Spies are the counter to enemy Politicians. A Spy with high Espionage can reveal enemy councilor locations, sabotage their missions, and protect your own councilors from hostile operations. |
| Operative | Command | Espionage | Crackdown, Purge, Assault Alien Asset, Hostile Takeover | Direct action and enforcement. Operatives excel at removing enemy councilors and securing alien assets. An Operative with 7 Command can single-handedly purge an enemy spy network from a controlled nation. |
| Celebrity | Persuasion | Investigation | Public Campaign, Boost Ideology, Sway Nation, Increase Stability | Influence operations without the diplomatic penalty of Politicians. Celebrities can shift public opinion and boost ideology quietly. Less effective than Politicians for direct control but draws less alien attention. |
| Officer | Command | Persuasion | Boost Military, Defend Nation, Improve Defenses, Military Coup | Military control and defense. Officers are essential once the alien invasion begins in earnest. An Officer with 6 Command can prevent military coups and maintain control of nations with high unrest. Often undervalued by new players. |
Core Stats Explained — What Each Stat Does
Each councilor has six stats: Persuasion, Investigation, Espionage, Command, Science, and Administration. Stats range from 1 (terrible) to 10 (maximum possible through level-up alone). Stats above 10 are possible with organization bonuses and equipment. When attempting a mission, the game calculates success probability based on your councilors stat minus the target nations resistance or the enemy councilors opposing stat. Understanding which stats matter for which missions is essential for efficient councilor development.
| Stat | Function | How to Boost | Recommended Threshold |
|---|---|---|---|
| Persuasion | Determines success chance of diplomatic and influence missions (Control Nation, Public Campaign, Sway Nation). | Level up the councilor, assign to a nation with high stability, use Celebrity or Politician orgs that boost Persuasion. | 6+ for G20 nations, 4+ for minor nations. 8+ for reliable G20 control without orphan investment. |
| Investigation | Determines ability to detect enemy councilors, reveal their locations, and defend against enemy intel ops. Also improves success of Gather Intelligence. | Level up, assign Investigation-boosting orgs, place in nations with high intel infrastructure. | 5+ recommended for any councilor operating in hostile territory. 7+ for dedicated counter-intel specialists. |
| Espionage | Determines success of sabotage, infiltration, and covert missions. Also improves resistance to enemy espionage. | Level up Spy profession, use espionage orgs, assign to nations with low stability (easier sabotage). | 6+ for reliable sabotage. 8+ for infiltrating well-defended enemy factions. |
| Command | Determines success of military and enforcement missions (Crackdown, Purge, Military Coup, Boost Military). Also improves orbital defense coordination. | Level up Officer or Operative, assign to nations with high military infrastructure, use command-boosting orgs. | 5+ for Crackdown in unstable nations. 7+ for suppressing alien-sponsored rebellions. |
| Science | Determines research speed bonus and success of Advance Research and Steal Technology missions. | Level up Scientist profession, assign to nations with high university infrastructure, use science-boosting orgs. | 6+ for meaningful research acceleration. 9+ for stealing endgame alien technology. |
| Administration | Determines how many orgs the councilor can effectively manage and improves resource generation from controlled nations. | Level up any profession (all councilors gain some Administration on level-up), assign administration-boosting orgs. | 4+ to manage 2 orgs effectively. 7+ to manage 4+ orgs without penalty. |
Key Mission Types and Success Factors
Control Nation
The most important mission in the game. Control Nation attempts to bring a nation under your factions influence. Success probability depends on your councilors Persuasion vs. the nations current allegiance and the Persuasion of any enemy councilor also attempting the mission. Control Nation has no turn limit; you can keep attempting until you succeed or are countered. Invest heavily in Persuasion-boosting orgs before attempting G20 nations. A failed Control Nation attempt increases the nations resistance for 12 months, so prep carefully.
Public Campaign
Public Campaign boosts your factions popularity in a nation without triggering diplomatic penalties. It is the safest way to increase influence. Use it to prepare nations for Control Nation attempts. Public Campaign success depends on Persuasion and is nearly impossible to counter, making it ideal for steady expansion. Celebrities are surprisingly effective at Public Campaign because their secondary stat is Investigation, which helps detect enemy interference.
Crackdown and Purge
Crackdown removes enemy influence from a nation you control. Purge removes enemy councilors from a nation through deportation or worse. Both missions require Command and are essential for maintaining control of unstable regions. A Crackdown mission with an Officer who has 6 Command will succeed even in nations with 70 percent unrest. Purge is riskier because the target councilor may escape or trigger a diplomatic incident. Always have a Spy gathering intel on the target nation before attempting Purge.
Advance Research and Steal Technology
Advance Research grants a flat research progress bonus based on the councilors Science stat. It has zero failure risk and should be run continuously on every Scientist. Steal Technology attempts to copy a technology from an enemy or alien faction. It requires Science and has a failure risk based on the enemys Investigation. Steal Technology is the only way to acquire alien tech before you defeat an alien fleet, making it extremely valuable in the mid game.
Organization Management — How Orgs Boost Stats
Organizations (orgs) are deployable assets that boost councilor stats, provide passive bonuses, or enable special missions. Every councilor can manage a limited number of orgs based on their Administration stat. A councilor with Administration 4 can manage 2 orgs effectively; each additional org beyond the limit imposes a penalty to all mission success rates. The most valuable orgs are stat boosters: the Political Machine org adds +3 Persuasion, the Research Lab org adds +3 Science, and the Intelligence Network org adds +3 Investigation and +2 Espionage.
Orgs are acquired through research, nation projects, and mission rewards. Some orgs are unique and can only be assigned to one councilor at a time; these should go to your highest-stat councilors. Common orgs can be mass-produced and distributed to your entire councilor roster. Prioritize giving stat-boosting orgs to councilors whose primary stat matches the org: a +3 Persuasion org on a Politician is more valuable than on any other profession because the Politician gets the full benefit of their primary stat bonus on level-up as well.
Orgs can be transferred between councilors but doing so costs MC and takes time. Plan org assignments carefully and avoid frequent reassignments. If a councilor dies or retires, their orgs become available for reassignment immediately with no penalty. Losing a high-level councilor is painful, but at least you get the orgs back.
Frequently Asked Questions
How do I recruit high-level councilors efficiently?
High-level councilors spawn randomly in nations your faction controls, but you can influence the odds. First, maximize the stability and development level of your controlled nations; councilors spawn with higher base stats in G20 nations with high GDP and stability. Second, build the Councilor Recruitment Institute project in your capital nation; this project increases the level and stat range of new councilor recruits. Third, check the recruitment pool every 6 months (January and July) because new councilors spawn on a semi-annual cycle. If you have excess MC, dismiss low-stat councilors (below 3 in all stats) to free up recruitment slots for better candidates. The single best investment in the early game is recruiting one Politician with 6+ Persuasion and one Scientist with 5+ Science before 2028.
What is the best way to level up councilors?
Councilors gain XP by successfully completing missions. The fastest leveling strategy is to assign missions with high success probability (70 percent or higher) repeatedly rather than attempting risky high-reward missions. For Politicians, spam Public Campaign in stable, friendly nations; each successful campaign grants XP and also boosts your Earth control. For Scientists, use Advance Research continuously; it has no failure risk and generates steady XP. For Spies, use Gather Intelligence on enemy factions; even partial success grants XP. Avoid assigning missions that have a high chance of failure because failed missions grant reduced XP and may injure or kill the councilor. Once a councilor reaches level 8-10, their stats become so high that almost all missions succeed reliably.
How does councilor transfer between factions work?
Councilor transfer is a mechanic that allows you to move councilors between allied factions (in multiplayer or when playing with AI allies). To transfer a councilor, open the councilor management screen, select the councilor, and choose the Transfer option, then select the destination faction. The receiving faction must have an available councilor slot (maximum 12 councilors per faction). Transferred councilors retain their level, stats, and orgs but lose any nation-specific bonuses from their previous posting. Note that councilor transfer is not available in single-player against AI enemies; it only works in multiplayer or when managing allied human factions. In single player, you can still recruit enemy councilors who have defected by successfully running a Sway Councilor mission, but this is rare and high-risk. Focus on recruiting and developing your own councilors rather than relying on defections.
