Sultans is a technology in Age of Empires II: The Forgotten that is unique to the Indians and can be researched at the Castle. Once researched, it increases the speed of all gold income (mining, trading, and Relics) by +10%.
Strategy
Sultans is the cornerstone to the Indians' success. Essentially, it makes Gold Miners work 10% faster, Trade Carts and Cogs generate 10% more gold per trip, and Relics generate gold 10% faster. For a civilization heavily reliant on gold intensive troops (Camels, Hand Cannoneers, Bombard Cannons), Sultans hugely benefits the Indians and should be researched as soon as possible.
The Sultans technology stacks with other bonuses. Hence, it is especially profitable when allied with an Aztec or Spanish player, which team bonuses increase the gold production of Relics and trade, respectively.
