Clan Hunts have made their return in Final Fantasy XIV: Stormblood. The only different is this time around Elite Hunts are daily, rather than weekly.
These hunts allow you to accrue Centurion Seals, which are used for purchasing a variety of items in Rhalgr’s Reach. They also provide a nice surge of experience, which is great for utilizing as a DPS when queued for a dungeon.
To unlock Clan Hunts, head to Estrild (X10.3, Y10.2) in Kugane. She will provide four quests, one after another, to unlock each layer of clan hunts.
Note that each layer of Clan Hunts have level requirements beginning at level 61. Elite Hunts require level 70, for example.
