Onslaughts are daily quests available from the Keeper at any of the Sourcewells on Ember Isle.
To complete this quest, players must stop 65 invasions at the current Sourcewell before they plant an idol at the Sourcewell. Also, at least one defense must be active and assisting, and at least one defense must survive, for the quest to update.
For more information about Sourcewells, the defense turrets, lifesprings and defense arches, see Sourcewell.
