In War Within Season 3, completing a Tier 11 delve gives you the “Cracked Keystone” quest right away.
How the Quest Works
The objective? Finishing any dungeon at Mythic +2 or higher will provide you with 200 
Valorstones, 15 
Runed Ethereal Crests, and 15 
Gilded Ethereal Crests.
Season 3 vs Season 2 Changes
This quest first appeared during the late Season 2 Turbo Boost event, but Blizzard decided to implement it right from the start in Season3.
Why This Matters
The quest means you don’t need to open the Great Vault or clear a Mythic +0 dungeon just to get your first Keystone to start the season!
