Gem Drop Ratio

The cost of upgrading stars can be massive but it is actually possible to achieve a high star set by just farming gems when you know how. Before you can start mass NPC farming you need to get as many heroes as you can. By the time you have the capability to build ballista you should have acquired about 80 - 90 good heroes. Farming gems will get them up through the early levels extremely fast. The whole key concept behind mass NPC farming is speed. When you are able to hit 80 to 160 NPC's within an hour you can farm every hour for as often as you like acquiring hundreds of gems a day.

You need to have your colonisation quest finished (400 cities colonised) to get the full benefit.


Gem Drop Rate

The actual gem drop rate between NPC's from lv6 to 10 doesn't seem to differ that much although the only real difference is that more blue/flawless gems drop the higher the NPC.
