Army Strength | You will want to get as many army slots as soon as possible, but don't rush the 3rd one, and ESPECIALLY don't rush the 4th one. The 4th army slot requires you to have a town hall of 25, so that will take a REALLY long time compared to other things. |
City Growth | stuff here |
Monster Hunting | stuff here |
Resource Gathering | You will want to be researching the ability to gather from higher and higher level resource tiles as you go along. It will help you be more productive for longer after you go offline. |
Grassland Grit | stuff here |
Badlands Brutality | Unless you want to attack people / reside mostly in the badlands, this should be near the bottom of your priority list |
