The new tower has finally been released to the public after a couple days of testing it.
How it works:
Every time you beat an npc you will get teleported to the next npc but if you lose a battle you will get sent to spawn without being able to /back. You have to be able to complete the whole tower with one team as you wont be able to switch it as you cant leave the tower and /pc is blocked.
After defeating each floor you will be rewarded.
Floor 1: 1 Masterballs + 10k
Floor 2: 4 Masterballs + 100k
Floor 3: 5 masterballs + 200k + random shiny pokemon
Floor 4: Legendary of choice +Random Shiny pokemon + 250k
