Your base of operations in Expeditions: Rome is your Legion outpost, and adding upgrades to it helps you solidify your presence in various regions of the map. As you lead your army to explore new lands, you'll need to know how this system works to succeed in battle.
This Expeditions: Rome guide explains the various mechanics and building chains found in the Legion Outpost, as well as upgrades to look out for as you play.
How to Unlock Legion Outpost Buildings and Upgrades in Expeditions: Rome
Since there are a lot of mechanics to discuss, we suggest you check out our other Expeditions: Rome guides on Praetorian/Centurion Recruitment and Perks, Conquests and Stratagems, and Pacification Missions to learn all there is to it. there is to know about these mechanisms.
For this particular guide, however, we'll be looking at features related to the Legion Outpost Management menu. You can access it by pressing the "O" key or by interacting with the tent in the outpost and the eagle in your base.
Praetorian Assignments and Upgrades
The first tab (see below) shows you the assignments available for buildings already unlocked. You can assign a unique companion or a generic Praetorian recruit to these buildings. While they're in the middle of a task, they won't be able to join you in tactical battles, so keep that in mind.
The second tab shows you the upgrade tree for your Legion Outpost in Expeditions: Rome. By default, only the Market is unlocked. This is where you will trade resources at the start of the campaign.
The other tabs will unlock as you progress. You will send the Legio VI Victrix to conquer landmarks, such as farms, iron mines, sawmills and tanneries, on the world map. On your turn, you will be given the tools that will allow you to fully construct these buildings/upgrades instantly.
Try to consider the resources you have. You don't want to accidentally upgrade something you won't need, only to find out that you need another iron mine in a different sector or region.
Important Legion outpost building chains
Below we list the main Legion outpost construction chains in Expeditions: Rome, along with their possible functions/assignments:
Barracks -> Garrison -> Praetorium
This is one of the most important aspects of your Legion Outpost in Expeditions: Rome. If a character is assigned to this chain, you will have a pool of new soldiers that can be hired. Choose a character with the Recruiter perk so that these soldiers are the same level as your main character. Subsequent upgrades also increase the levels of possible recruits.
Armory -> Forge -> Foundry
Upgrading this building chain allows you to craft higher tier weapons, armor, and tactical items. Still, you need a Praetorian with the Crafty perk to do this job. You can find out more in our crafting guide and unique item guide.
Scout Tent -> Ambassador Tent -> Emperor Tent
This chain is quite important because it allows you to replenish tactical items such as caltrops, pila, torches, bandages and others. Subsequent upgrades also increase the number of restocks.
Award someone the Freeloader perk to get an extra free resupply. Otherwise, you will use raw materials and denarii. There is another related perk called Scavenger which simply reduces the time it takes to complete the process and as such is not as useful as the Freeloader perk.
Dispensary -> Infirmary -> Hospital
This build chain will deal with injured characters over time (the alternative being the Triage menu). Likewise, this is the only place severely injured characters can recover. If you don't heal them, they will die. Future upgrades will only reduce processing time, so don't prioritize this channel. In any case, you can find out more in our healing and injury guide.
Bath -> Bathing
A character with the Social perk can be assigned to the Bain to increase army morale by +4 points every 32 in-game hours. Alternatively, you can place a party member here if their loyalty is very low. It will slowly improve to a certain threshold depending on the upgrade level. You can learn more in our guide to Rhetorical Style and Loyalty.
Workshop -> Factory -> Arsenal
The Workshop Building Chain is where you can assign a Praetorian with the Architect perk to research new Stratagems. These are cards that are randomly drawn in battles, strengthening certain aspects of your army and weakening your enemies. Upgrades allow for higher-level stratagems. You can find out more in our Conquests and Stratagems guide.
Note that Praetorians will leave some assignments once the process is complete. You will need to return to your base (where Legio VI Victrix is ​​camped) to reassign them.
For the rest, these Legion outpost chains don't require you to assign characters.
Market -> Emporium -> Trade
Upgrades simply increase the number of resources sold, while making the merchant's prices more advantageous. You can find out more in our resources and trading guide.
Palisades -> Walls -> Stone Walls
These upgrades will simply increase the strength of your Legion in case your base / where your army is camped is attacked.
Stock -> Warehouse -> Warehouse
Similar to walls, but this chain will increase your legion's strength when conquering territories.
Finally, the third tab of the Legions Outpost allows you to customize the colors and emblems of your Legion and Praetorians in Expeditions: Rome. Picks here are unlocked as you progress through the campaign, completing main quests and side quests along the way.
And that's what you need to know about upgrading your Legion Outpost in Expeditions: Rome. For more tips, head over to our guides hub.
