How to Access Seething Realms
Finding Realmwalkers and Portals
To enter Seething Realms, players must defeat Realmwalkers, powerful elite enemies that spawn in specific locations.
Realmwalker spawns are marked by a white portal icon on the map.
Hatred-infested zones (marked with a green skull) indicate nearby Realmwalker activity.
Estuar spawns a Realmwalker every 15 minutes, while Nahantu sees one every hour.
Defeating a Realmwalker opens a portal to a Seething Realm, a time-limited dungeon requiring strategic execution to claim its rewards.
Mastering Seething Realms Mechanics
Dungeon Structure & Realm Gates
Upon entering a Seething Realm, players will face waves of scaling enemies that test their combat efficiency. The dungeon’s Realm Gate is a critical point where you must:
Choose a Path – Each path influences the type of Seething Opal you’ll receive.
Offer Materials – Higher-quality materials improve drop rates for better rewards.
Defeat the Final Wave – Clearing all enemies unlocks the final rewards and Seething Opals.
