In God of War, our primary weapon, the mighty and faithful ax Leviathan, it can be upgraded up to five times to unlock more and more power and new skills. Upgrading it to the maximum will unlock the "Worthy" trophy.
To do this we will need the object Frozen Flame which cannot be purchased anywhere, but will be dropped by specific bosses during the adventure. The last boss battle that will reward us with an Frozen Flame will be the one against Magni and Modi during our visit to the Corps of Thamur.
The latest upgrade, however, will only be available after unlocking the realm of Niflheim (here is a guide on how to unlock it as soon as possible). You will find the last Frozen Flame in the shops of Brok and Sindri and can be exchanged for the item "Frost Mists of Niflheim". This item can be found in the central area of Ivaldi's workshop (the one with the gashes in the Kingdom) inside a chest that requires 5.000 Misty Echoes to be open; you can't go wrong, it's the only case that requires that amount.
You just have to arm yourself with good will and go into Ivaldi's dungeon to accumulate Misty Echoes.
