Stiel is the second hardest quest-related boss you'll face in the game. In fact, in the entire game, he's the hardest human that you'll ever fight and would have been a pretty cool character to have in the battle of the world.
It's a good idea to start the battle with either variable arts or Mystic arts (if you have half HP that is). Just be careful of the very strong hyper arts that Stiel has because they will easily knock a party member out early in battle. What's the most annoying part of this battle is that Stiel can block most of the hits that your party member will hit at him. This is why variable arts and Mystic arts come into play for this battle.
