Challenges are done using cheat mode level select (give yourself lots of gold, throw out unneeded weapons with J, assemble loadout, exit and enter sanctuary by teleporter to save it, level select the boss. Return to sanctuary in pause menu to reset.)

Challenges are designed to make boss fights more exciting and longer lasting. Some test game knowledge you may have missed.
