To unlock your mount, Torrent, in Elden Ring, follow these detailed steps:

1. Locate the First Site of Grace After the Stranded Graveyard:
– After emerging from the Cave of Knowledge, you will find yourself at the Stranded Graveyard.
– From there, head west towards the first Site of Grace called “The First Step.”

2. Travel North to the Church of Elleh:
– From “The First Step,” travel north along the beige path indicated on your map. This path leads towards the northeast.
– You will pass through a forest path and eventually reach a broken-down structure near the beginning of the road.
– Inside this structure is the Site of Grace called the “Church of Elleh.”

3. Activate the Church of Elleh Site of Grace:
– Rest at the “Church of Elleh” Site of Grace to activate it. This will prompt Melina to appear.

4. Interact with Melina:
– When Melina appears, she will offer you a bargain. Accept her offer to receive the Spectral Steed Whistle, which allows you to summon Torrent.

5. Summon Torrent Using the Spectral Steed Whistle:
– Once you have the Spectral Steed Whistle, equip it in your Quick Items menu. This will allow you to summon Torrent instantly by using the whistle.
– To mount Torrent, simply use the Spectral Steed Whistle. Your character will immediately appear atop the horse.
– To dismount, use the Spectral Steed Whistle again or click in the left stick to jump off quickly.

6. Control and Use Torrent:
– While mounted, you can sprint by holding Circle or B, which will give you a short burst of speed without depleting stamina outside of combat.
– You can also double-jump with Torrent, which is useful for scaling cliffsides and dodging enemies.
– To attack, use the right trigger for right-side attacks and the left trigger for left-side attacks. You can also use magic and flasks while mounted.

7. Heal Torrent:
– If Torrent takes damage, you can heal him by feeding him Rowa Raisins, which can be crafted using Rowa Fruit found throughout the Lands Between.
– Alternatively, you can use a Flask of Crimson Tears to heal Torrent if he dies temporarily.

By following these steps, you will be able to unlock and use your mount, Torrent, in Elden Ring.
