Title: Diablo IV - Vessel of Hatred - Realmwalker + Seething Realm
Description:
A new mechanic was introduced with Vessel of Hatred and Season 6 of Diablo 4. So called 'Realmwalkers' are wandering around. To defeat them you have to beat several waves of enemies while hunting down the Realmwalker. After beating the waves the Realmwalker becomes vulnerable for a short time. After that you have to defeat more waves until they become vulnerable again. If you defeat the Realmwalker, they open a portal to the Seething Realm. This is a new type of dungeon where you can use Realm Gates to choose the path forward. Finishing the dungeon will drop a new type of elixir called Seething Opals. These give you huge boosts - 15% more XP and other effects like increased drops of gold or equipment.
