When to research
Multinationalism provides an immediate reinforcement: 8 random European mercenaries. Research when this force fills a current army need and can reach the fight in time; reserve population and set a safe gather point rather than starting it as an emergency response. Use the Trading Post or Tambo (Inca only) for research. Research takes 30 seconds and costs 1,500 coin.
A mixed European mercenary delivery
Multinationalism is a Fortress Age technology researched at a Trading Post or, for the Inca, a Tambo. It costs 1,500 Coin, takes 30 seconds and delivers eight random European Mercenaries. The unit mix is random, so it is not a guaranteed counter to one enemy type.
Use it as a flexible reinforcement
The technology can add a varied force, but its value depends on the units delivered and available population. Prepare a rally point and supporting army. Research when a mixed reinforcement can affect the next engagement.
A random eight-Mercenary group
Multinationalism costs 1,500 Coin and takes 30 seconds in the Fortress Age. It delivers eight random European Mercenaries, so the player cannot choose a guaranteed counter or exact unit mix when starting the research. Prepare enough population for the group and a rally point that can bring the delivered units together with the existing army. Its value is flexibility and immediate reinforcement, balanced against uncertainty about the roster.
Account for the Inca access route
The technology is researched at a Trading Post, or at a Tambo for the Inca. Before paying the Coin, consider whether a mixed group can help the current fight and whether the army can support whichever Mercenaries arrive. If the opponent has one dominant unit type, a technology that guarantees a specific counter may be more dependable. Protect the production site and begin early enough for the 30-second research and arrival to matter.
