The Tower of Challenges was located to the South of Hero City.
It was a special place.
Because the Tower of Challenges had no level requirement, anyone could enter, but only one person could enter.
If you entered at level 20, the tower would have a level 20 monster.
If you entered at level 30, the tower would have a level 30 monster.
It might seem like a suitable place for everyone to level up, but that was not the case.
This was because the Tower of Challenges had a very difficult part.
Players were not allowed to use their own potions!
With this, players had to be extra careful when entering the Tower of Challenges.
If they did not have the skills to recover their HP and mana, they would not go far.
They might as well go to other leveling grounds.
Hence, in everyone's eyes, the Tower of Challenges was only suitable for two types of players.
