You become a Minor God from God of War's Greek Pantheon. This gives plenty of abilities.
Sleep is irrelevant, food and water is not even needed. Your skin, blood, and more are all able to completely ignore mortal attacks. A sword that does not surpass enough power to split an island cannot even harm you.
Immortal slaying weaponry has similar effects to a divine-attack, ignoring your defense.
Your body heals quick, able to survive fatal wounds effortlessly.
On top of all of this, you can shapeshift into different forms. Your power grows as you age.
You have a domain, but it is minor. You also get power through worship and might be able to ascend into a greater god if an entire continent worth of people worship you.
