God of War Ragnarok has 8 Frozen Flame Locations. They are used to upgrade the level of the Leviathan Axe, one of your weapons. The Leviathan Axe starts at Level 1, using 8 Frozen Flames upgrades it to Level 9 which is the maximum (Level 1 Starting Level + 8 Frozen Flames = Level 9).
You can use the Frozen Flames at the Blacksmith to upgrade the axe. This also increases your average equipment level as seen in the top left corner of the Weapons Menu. The higher your overall level, the more powerful you become. Each level also increases the damage of the axe.
You get all Frozen Flames automatically while going for 100% Completion. The majority is dropped by mandatory story bosses. If you forgot to loot one, the item is automatically placed in the blue chest at the blacksmith and can be retrieved from there.

Hash says
I’ve just completed the game, with 100% completion, and have discovered that my Leviathan Axe is at level 8. During the game I noticed that something strange happened – when rescuing The Traveller, the dragon I was meant to fight instantly died and vanished, meaning my favour was complete without me fighting it. I believe this is the reason why I didn’t get that frozen flame and, therefore, why my Axe is stuck at level 8.
This is probably the 14th glitch I’ve encountered in this game to date.
