Hope to hear from you again when you've beaten the Spectator, the other Spectator, Flind, the Hook Horrors, the Duergar, the Gith, Bernard and his Armors, the Kuo-Toa, the Minotaurs, the Mask of Vengeance, the Hag and the Bulette, and defended the grove from Minthara's hordes.
But it's a good sign that beating the Owlbear has pumped you up so much that you felt the need to share!
There's no real need for cheese (except possibly against the Bulette) - good strategy, and making sure your party has the best available equipment at all times, is usually enough, barring freakish enemy die rolls.
