Lost Ark Netherworld calculator

In Hell you descend as deep as you can within a set number of descents: each descent goes down 1 to 20 floors with equal chance, and rewards grow stronger every 10 floors. The Netherworld pays far more, but a monster of the same attribute as the mark above your head kills you, and dying with no revives left fails the run without rewards.

Hell in the game

1. You descend with a key; its tier sets the quality of the rewards.
2. When your descents run out or you reach floor 100, you choose one of the reward chests for that floor; altars on some floors grant effects that help you go deeper.
3. In the Netherworld, Quit and Claim Rewards ends the run and pays the reward of the floor you reached.
