Volcanic Vents are new World Events exclusive to The Elder Scrolls Online: High Isle, and there are seven such locations across High Isle and Amenos Island. Volcanic Vents are large areas with rising magma and lava that spawn waves of fire-based monsters like Imps, Flame Atronachs, and Vulk'esh. The waves of enemies end with the powerful final boss, usually a Fire Behemoth or similar creature, with two million HP or higher. Because of this, it is not usually possible to tackle an Elder Scrolls Online Volcanic Vent as a solo player, and players should plan to go with at least a companion, if not a full party.
On the Elder Scrolls Online map, Volcanic Vents appear as a whirlwind symbol. Part of the lore and story of The Elder Scrolls Online: High Isle includes working with some Stonelord druids to determine why the Volcanic Vents are opening in the first place and close them. If a Volcanic Vent is active, it will be pulsing and have crossed swords behind it. Before traveling to an active Volcanic Vent, players should try to improve their flame resistance, get together with a group of players, and make sure they've recruited and can call upon at least one of the two new Elder Scrolls Online: High Isle companions. This will give them the best chance of survival.
