# Endless Tower The **Endless Tower** is the competitive climbing mode: floor after floor, ever stronger, without end. Your highest cleared floor is your ranking value. ::: info Where to find the tower You reach the Endless Tower through the [Dungeon](https://mebulalegends.bitmeup.com/wiki/en/guide/dungeons/) tab, in the "Endless" section. It costs **no energy** and has **no daily limit**: you can attempt the next floor as often as you like. ::: ## The same for everyone A floor's enemies are generated **purely from the floor number** and a fixed global seed. Floor 47 looks **identical for every player**. In the tower you fight **Mebuli against Mebuli**, the enemies are Mebulis with their own ultimates, which they charge and fire during the battle. ## Structure of a floor - A floor is a **multi-wave battle**. Between waves there is **no healing**. Your health carries through the entire floor. - Between **floors** your team heals **fully**. - A win unlocks the next floor. Progress stays **forever** and is never reset. | Floor | Waves (base) | |---|---| | 1–25 | 2 | | 26–50 | 3 | | 51+ | 4 | Two surcharges come on top: - **Boss floor:** every 10th floor (10, 20, 30 …) gets **one extra wave** with a single strong boss. - **Outlier floor:** roughly every seventh normal floor has **one more wave and tougher enemies** (stats × 1.25). Which one that is stands fixed and applies to everyone alike. ## Difficulty curve Enemy power grows by **× 1.13 per floor** and is never reset. The enemies' ultimate level rises by one every six floors, up to level 5. ## Rewards | Occasion | Reward | |---|---| | Clearing a floor for the first time | **10 energy** | | Every 10 floors, up to floor 200 | **1 prism seal** (20 in total) | | "Tower Climber" achievement | at floors 10, 20, 30, 40 and 50 | Alongside story, realms and dungeon grades, the prism seals are one of the few sources for the deep nodes of the [prestige tree](https://mebulalegends.bitmeup.com/wiki/en/guide/prestige/). ::: tip Climb in stages Because your team heals fully between floors, each floor is a clean single attempt. If you stall, targeted gearing up beats another run with the same team. :::
