Quick table to show difficulty and opponent:

Difficulty level 1 2 3 4 5
Opponent level 60-69 70-79 80-89 90-99 100-105

Rewards will be progressively better as you both try harder difficulties and as you gain more tiers in each difficulty.

This is part of your daily routing, you only have to fight it once daily to earn credit, but can only fight it 5 times each day. Better to battle it 5 times each day, than be stuck trying to complete it Saturday night imho.
