A Heart For A Head is one of those branching quests in Assassin’s Creed Odyssey and stems from the quest The Priests of Asklepios.
Your role is to find a white bull because it apparently heals certain diseases.
Here’s a brief walkthrough of A Heart For A Head in AC Odyssey.
Locate the sacred bull
Your first objective is to find this sacred white-colored bull in Argolis. The exact location appears to be in Asine Ruins, which is a heavily guarded area.
You will notice that this white bull ended up inside this area and there are guards all over.
There are also a couple of location objectives you may want to do, such as freeing captives, killing the bandit leader and finding an ancient tablet.
Unfortunately, the sacred bull is already dead, so your objective now is to collect the bull’s heart instead.
You can just sneak through the bandits to collect the bull’s heart. Otherwise, just get rid of all of them and clear the objectives.
Bring the heart back to the healer
Once you’re done, go back to the healer where you started this quest. There will be a conversation where you can choose only one person to save, since all of them require the heart.
I’m not sure if the conversation gives different endings but I chose the little girl.
And that’s it. You get a spear and a mace as your reward.
