When to research
Coatlicue Worship can deliver up to 15 groups of Otontin Slinger before the 30-minute cap. Research early enough to receive more intervals, reserve population, and keep a safe rally point so the arrivals can join the army. Use the Aztec House for research. Research takes 10 seconds and costs 500 coin.
Research timing controls the award
At the Aztec House, the Commerce Age research costs 500 Coin and takes ten seconds. It grants one Otontin Slinger per two minutes of elapsed game time, up to 30 minutes. Researching earlier preserves more installments; waiting until the army needs reinforcements forfeits earlier timed awards. Keep population capacity available for the delivered units.
Timed reinforcements rather than a one-time delivery
Coatlicue Worship creates a stream of Otontin Slingers tied to elapsed match time: one is awarded for each two-minute interval, up to the 30-minute limit. It is not a single batch whose size is fixed when the research completes. Researching earlier lets more of the scheduled intervals occur while the technology is active; waiting until a battle is already underway can mean that earlier awards have passed. The Aztec House research itself costs 500 Coin and takes ten seconds from the Commerce Age. Leave population room for the arrivals and consider where they will gather so reinforcements do not appear too far from the force that needs them.
How it fits an Aztec plan
The technology is most useful when the Aztec economy can spare Coin without delaying a necessary unit or age-up and when the player can turn gradual arrivals into sustained pressure. Otontin Slingers are ranged support, so the timed stream complements rather than replaces the rest of the army. Protect their approach with units suited to absorb contact, and keep an eye on population as the interval deliveries accumulate. If the match is likely to end before several intervals pass, compare the time-dependent benefit with an immediate purchase that affects the current fight.
