Endless Tower is the most iconic instance in Ragnarok Online - a massive 101-floor tower rising from the ocean, filled with increasingly powerful monsters and MVPs. Parties must climb floor by floor, facing waves of enemies and culminating in a battle against Naght Sieger at the summit. The tower is the ultimate test of endurance and teamwork.

Overview

Long ago, Captain Janssen's fleet was wrecked near a mysterious tower in the middle of the ocean. His crew entered seeking shelter and never returned. Now, the captain seeks adventurers brave enough to explore this humongous tower that scrapes across the sky.

The Endless Tower features 101 floors with monsters that increase in difficulty. Every 5 floors contains a mini-boss or MVP, with major checkpoints at floors 25, 50, 75, and 100. The tower can be cleared over multiple sessions thanks to checkpoint saves.
