Eternal Life Trophy in Spelunky (PS3, PS4 & Vita)
Obtain the Ankh.
How to unlock Eternal Life
The Ankh is an item that acts as a second life, respawning you in the level you died in, rather than forcing you to start the game over with. Details on how to obtain the Ankh can be found in City of Gold. Keep in mind, for the trophy to unlock, I needed to purchase the Ankh for $50,000. Stealing it and escaping the Black Market didn't count for the trophy.
