Getting an Edge
Upon registration, you received 15 crystals, which you can use to activate your first bonus. I recommend you activate those 3 Extra Building Queues, so that you'll have 4 structures at a time in the building queue.
Bonuses can be activated at the RCV and require a specific number of crystals. You can refer friends to get crystals, spread the word about Asgard Heroes or you can buy them.
The High Council appreciates any donation received and will allow you to even relocate to new outposts, for the right price. The crystals can also be used to activate production bonuses (+20%) for all resources available in the game.
