The Dynasty achievement is obtained once you reach tier 6 with your Clan. To do this, you’ll need to reach specific milestones and increase your Renown, which in turn will increase the experience and tier of your Clan. If you need help with earning Renown, see our How to Gain Renown page. If you’re just starting out to reach Clan Tier 1, we’ve covered that in our Rebuild Your Clan page, which covers the basic process of increasing your clan tier.
