Instead of reducing voltage, it increases it. This is called a transformer. It has two main sets of windings, a primary winding and a secondary winding. The difference in the number of turns in each winding determines if the voltage out will be higher or lower than the voltage in and by how much. A Tesla Coil has very few turns on the primary (input) side, and many turns on the secondary (output) side. This increases the voltage tremendously. But a Tesla Coil does much more then increase voltage, it increases frequency. The capacitor and spark gap work together to create a very high frequency pulse to drive the primary coil. Tesla designed it this way because once you create very high voltage electricity at a very high frequency, you can create a field of energy that you can transmit power with. All of this was running through Nikola's head as he designed the amazing invention
