Path to Glory 23

Path to Glory 23 has 3 challenges, and 40 days to complete them in.

To complete this Path, you must:

1. Complete 50 Daily Quests
2. Defeat 475 Encounter Camps.
3. Gather 500 Raid Keys

Your rewards for completing these missions are:

1. 30,000 gold
2. 1 Legacy Chest
3. Postman's Boots (March Speed +50%, Attach vs Encounter +40%, Health vs Encounter +85%, Champion XP +8%)

For the 1st challenge, you just have to do the daily quests, all 5 of them, so this should take 10 days.
For the 2nd challenge, fire up the Encounter Cooldown, and hit every camp you can see.  They all count.
For the 3rd challenge, gathering and camps are the only way to go. Make sure your alliance has keys needed for your DC, or you can't earn keys.  If this happens, get a War General to start your DC, or change alliances to one that still needs keys.
There is also a Raid Key Finder that you may have in your inventory, which increases the chances of finding a key for 12 hours.  It shows up on the Utility tab, in the hour glass section.  It can't be purchased for gold or favour.
