Garrison Resources are something you may casually dismiss while leveling up. Quests are granting them left and right, you're not having any problems building your first building or two, and everything looks peachy. So you're thinking that you may as well start buying those Excess Potions of Accelerated Learning for 100 resources a pop, right? Wrong! Anyone who has spent hundreds of their precious resources on those potions could be in for a rude awakening once they hit level 100 and realize they need 2000 resources to upgrade their garrison. Don't let me stop you from buying the potions if you truly need to get to 100 a few hours earlier, but don't say I didn't warn you.
Either way, you're going to run into a resource problem eventually. Garrison Resources are the main bottleneck for progressing every aspect of your garrison. Given enough time, you will eventually generate enough resources to do everything you want. But we're not all patient people, are we? Here's a few tips to get your hands on some resources as soon as possible.
