Resumen
Guerrero águila de élite is the late-game upgrade for Guerrero águilas, improving the line for continued raiding and front-line use. It is strongest when supported by an economía that can replace losses and by unidades that handle its counters.
Effect and affected unidades
The Castillo upgrade improves eligible Guerrero águilas to their elite stage, raising their effectiveness in late-game fights. Their mobility remains useful for map control and raids, but stronger static defenses and mixed armies require selective engagements rather than repeated frontal attacks.

Research cost and timing
Research the elite upgrade when your civilization has access, your Guerrero águila numbers justify the investment, and you can continue production afterward. The technology is less valuable if the opponent's composition has shifted toward counters or if the game will end before the stronger stage can be fielded.
