Once More Into the Tower

Once More Into the Tower is a scaling mission which uniquely defaults to a difficulty corresponding to your highest achieved Item Power. Use of the Lucky Pachinko Ball item allows selection of difficulty options ranging from Elite 1 to Elite 17, but completion of Once More Into the Tower on any difficulty lower than the highest available one will result in reduced rewards.

The Peculiar Box is an extremely rare random drop from multiple sources.

It can drop from Reward Bags received from content, including missions from the Scorched Desert all the way to South Africa, and even Shambala. Talisman, Weapon, and Glyph Reward Bags may contain the Peculiar Box.

It can also drop from the rare Reward Chests that spawn after defeating dungeon, lair, or regional bosses.

To be able to use the Peculiar Box and start Once More Into the Tower, you must complete the Capstone achievements for each Region and its zones. Capstone achievements for each zone are those that require the completion of all missions within a particular zone, its dungeon successfully cleared on any difficulty if the zone has one, all champions defeated, and the zone explored.

For those unwilling to wait for the Peculiar Box to come to them, the Peculiar Box can be purchased for 2,000,000 Marks of Favour from Doctor Caligari in the Hollowed Halls (600,200) of Agartha. All requirements to use the box must me met in order to purchase it.

Use the Peculiar Box to start Once More Into the Tower.

Completing this mission awards Spoils of the Southern Tunnel.
