The Full Belly trophy / achievement is unlocked once you obtain all Apples of Iðunn and Horns of Blood Mead from Nornir Chests in God of War Ragnarok. The apples upgrade your health pool, while the Horns of Blood Mead upgrade your rage. There are 35 Nornir Chests to be found throughout the realms in the game, and each one offers a puzzle which requires you to hit three different runes in specific ways. If you’re missing any of the Nornir Chests, you can see the table below for each one, which also provides a link to the associated video guide.
