Brazier question

[nub]

How do I know where they are and whats the point of unlocking all of them?

All braziers are located on the Lake of Nine's towers.

Lighting them all grants you the "Valkyrie's Bane" enchantment, which reduces all damage from Valkyries' attacks by 5%

Okay thanks.

but literally you have to get to the end of the game to light them all, just right before the last boss fight. Which is a shame since i had already killed all the valkyries.
