The dark atmosphere realm of Valhalla
Valhalla is the only region in EOS where Guilds fight for glory and acquire Valor Essence. This item is an essential material for profession level 60 or above to crafting top-tier items. You could acquire it by collecting it or by killing monsters in Valhalla.
Valhalla is only accessible to Guilds which have declared war on at least 5 other Guilds. Once your Guilds fulfill that requirement, you can enter Valhalla by talking to the Valhalla Entry Guide in Ignea. He will let you choose which part of Valhalla you want to travel to. When you’re ready, talk to the Exit Guide.
