Once there, go into the basement and you will find the Champion's Challenge activity and the Imp Champion waiting there. You can not use any special attacks to defeat the Imp Champion

Imp Champion's Attacks
The Imp Champion uses Ranged attacks and it will teleport to different areas of the arena. Magic or Ranged attacks are recommended as you would be continually attacking it, instead of running around attacking with melee.

A new banner is hung in the arena under the Champions' Guild to celebrate your victory.
