First Guarantee
First Guarantee is a Commerce Age technology for the Mexicans in Age of Empires III: Definitive Edition. After the Plan of Iguala Home City Card is sent, it lets a defeated Padre respawn for free at the Home City shipment point instead of being retrained at the Cathedral.

Effect & research conditions
Research it at the Cathedral; the listed research time is 15 seconds. The technology changes the Padre’s return after defeat and does not protect him from being killed or respawn other units. The respawn occurs at the Home City shipment point, so the Padre must travel back to the front. The Wiki notes that retraining the Padre at the Cathedral takes twice as long as the respawn route, making the upgrade relevant when the hero is used repeatedly.
Research condition
Mexicans; Commerce Age; Cathedral; requires the Plan of Iguala Home City Card
When to research
Research it when the Padre is an important part of scouting or support and the match is likely to last long enough for the respawn to matter. Keep an escort or safe route for his return; free respawn does not make a solitary Padre safe. If the hero is rarely exposed or the game is nearly over, spend the Cathedral time on a more immediate need.
Respawning is not the same as staying alive
First Guarantee grants a return after the Padre falls; it does not grant extra resistance or prevent the defeat. Because the return point is the Home City shipment point, the hero may be away from the active battle for the time it takes to travel back. Protect that return journey and use the Padre’s support role where allied units can cover him.
Card access and practical timing
The Plan of Iguala card must be sent before the Cathedral can research the technology. Once the 15-second research finishes, future Padre defeats use the free respawn behavior described by the technology. This is most useful when the Padre is repeatedly involved in important actions; it has little immediate value if the hero remains safely at home or no further fights are expected.
